Hubbell Power Systems, Inc. (HPS) announced its plan to co-produce a second film in the Storm Soldiers franchise with Tytan Creates. Storm Soldiers II: Weather Warriors will document the story of one lineman and his two families, the one at home and the one on the line. It is an intimate portrayal of the rigors of the job, the love, and the sacrifices made in the field and on the home front. Open casting calls begin at the International Lineman’s Rodeo October 16. Tytan Creates will be on site to film linemen who want to star as the Storm Soldier. Following the rodeo, the call for talent will be conducted through social media channels such as Facebook and Instagram through the end of October. Once the Storm Soldier is selected, the movie promotion will ramp up and will include interviews and outtakes shared to social followers. HPS and Tytan Creates produced the original StormSoldiers movie and since its release in 2013 have developed a strong following amongst the linemen community. This time around the collaboration includes sponsors, Altec, ® Inc. and Burndy, ® LLC, to tell a deeper, more personal story. Altec is a leading provider of heavy equipment products and services to the electric utility, telecommunications, tree care, lights and signs, and contractor markets. Burndy, a subsidiary of Hubbell Incorporated and sister brand of Hubbell Power Systems, provides reliable tooling, connection systems and solutions to the utility, telecommunications, data, industrial and instrumentation, and energy industries. Ken Carlson, HPS VP of Global Sales and Marketing Services explained, “Having sponsors like Altec and Burndy that are iconic in our industry is a testament to the spirit of the linemen community. We are working together to raise awareness about what linemen do and sometimes sacrifice to bring power to our daily lives.” Filming of Storm Soldiers II: Weather Warriors will follow the selected Storm Solider and weather related outages across North America. As with the first film, HPS and Tytan will seek consultation from Hall of Fame Lineman, Mike Glueckert of NorthWestern Energy to ensure technical accuracy.

We are working together to raise awareness about what lineman do and sometimes sacrifice to bring power to our daily lives.

Southern California Edison Moves Toward Bare-Hand, Live-Line Work - Daniel Carbajal Transmission Construction Methods Manager, SCE all on the by patricia irwin, PE We want to be sure that we have the right products and the right training before we begin this work. Our employee’s safety is paramount.

Bare-Handed Currently, SCE employees work on energized lines with specialized tools, like hot sticks, which keep them at a safe physical distance from the line and electrically isolated from the line voltage. To illustrate, consider how a worker changes out a cross arm. He uses a hot stick or rubber gloves to lift the line off the cross arm. The line is energized and at a certain voltage (12-kV, for example), but the worker never experiences the line voltage. He is at zero volts, thanks to the insulating properties of the hot stick or rubber gloves.

Southern California Edison provides power to 14 million people in its 50,000 square mile territory. The utility has 12,782 miles of transmission line that has to be maintained. Historically, maintenance work was done while the lines were de-energized, but due to line loading constraints, it is getting harder and harder to take transmission lines out of service. One way to address this problem is to perform the work while the lines are still energized, but live-line work is limited to what an employee can do with a hot stick. Daniel Carbajal, Transmission Construction Methods Manager at SCE explains, “We do live-line work and we do hot stick work, but that is not the same as bare-hand, live-line work, which is what SCE plans to do in the future.”

Bare-hand, live-line work is significantly different.

Carbajal continues, “WithEHVbare-handwork, theemployee ‘bonds’ to the energized line (in this case as high as 500-kV). This matches the worker’s voltage and the line voltage.

line

The process is called ‘building a variance.’ According to Carbajal, it is like preparing a business case, but it is not easy.

During bare-hand work, workers wear a Faraday suit bonded properly to the conductor and become one with the electric field at the line voltage.” Build a Variance California law specifically bans bare-hand work. In order to do it, a utility has to get permission from the California Occupational Safety and Health Administration Cal-OSHA and meet state and federal requirements. “We had to demonstrate to Cal-OSHA (while meeting Federal OSHA guidelines) that this can be done safely. We had to show them the training that we are going to do and what tools we are going to use. We had to explain exactly what type of work we will be performing and at what voltages,” explains Carbajal.

To begin, SCE benchmarked the bare-handing programs of other utilities, including Pacific Gas & Electric, San Diego Gas & Electric, and NV Energy. Then, the utility began evaluating what kinds of tools and training it would need.

Tools SCE called Hubbell Power Systems (HPS) for its expert advice.

“We’ve been working with HPS and their line of Chance ® tools for years and knew they hadwhat we needed – particularly in the extra high voltage (EHV) arena where strength is a critical issue. If we need to change out a string of insulators on a high-voltage line, a worker has to support the weight of the conductor during the change out. Chance tools can support that kind of weight.”

To help with the variance, HPS Territory Manager, Bryan Jones, recommended that SCE bring in Jim McDonald, a former HPS employee, to help with procedure writing, training, and tool review. McDonald has years of experience in bare-hand, live-line work. McDonald and Jones went through all of SCE’s tool trailers to make sure the utility had the right tools. Thismeant evaluating tools that were, in some cases, 30 years old. There were even some specialty tools from the 70’s and 80’s. Jones explains, “We inventoried all of their trailers and materials and then provided SCE with a list of items they needed, including some specialty yokes that are not standard catalog items. We also identified a large number of items that needed to be reworked and retested.” Unfortunately, no local companies could do the refurbishing work. So HPS worked with SCE to identify local companies that could be trained to do the work and arranged for those vendors to get training at an HPS facility. Historically, maintenance work was done while the lines were de-energized, but due to line laoding constraints, it is getting harder and harder to take transmission lines out of service.

Documentation SCE purchased training materials and manuals from McDonald to augment the materials they were preparing for the variance. McDonald also helped SCE document all the safety and work procedures it will use, including: • What voltages the variance applies to • How workers will be trained • Safety procedures • How worker safety will be monitored

• What tools will be used • How tools will be used • How the tools will be maintained • How the tools will be tested

Training With the variance mostly complete and under review by Cal OSHA, SCE turned its attention to training. Fortunately, while working on the variance, the utility was in the process of building a 500-kV training facility near an old power plant near Daggett, CA. Carbajal points out, “The facility is in the desert because the transmission world is bigger, taller, heavier… the toys are bigger. So, we needed space. We worked with our transmission training organization to put up four, 500-kV towers on a de-energized line section. Our plan is to use it for as much training as possible – helicopter, bare-hand, and hot sticking.”

By January 2015, SCE workers should

be ready to perform EHV bare-hand,

live-line work in the field. It took

three years of effort - working with

employees, vendors, and CAL OSHA

to get permission to do it.

Working in conjunction with SCE’s Transmission Training Organization and the Transmission Construction Methods Group, McDonald conducted a three week training class for SCE trainers, who will teach the lineman how to do bare- hand, live-line work. McDonald has conducted similar classes for the Salt River Project, SanDiegoGas & Electric, Bonneville Power and the Western Area Power Administration. “The first few days were all classroom training. We went through all of the theory behind bare-hand work, the equipment and all the tools. We laid out the tools and hardware to see what SCE had and made sure it would work for what we were going to be doing there. The rest of it was hands on training,” explains McDonald. “We worked on ‘V’ string configurations on the 500-kV line. We practiced using three different methods to access the work area. First, we worked off of a ladder to reach the conductor. Second, we used an insulated aerial device--the bare-hand bucket--to access the wire. And, we practiced using ropes,” continues McDonald. Members of SCE’s corporate safety team came out for a day to fine tune the program, and representatives from Cal OSHA spent a day at Daggett during the last week. They observed the training, including the tailboard (pre-work safety) briefing, step by step work procedures, use of the aerial device, the inspection of tools and the use of personal protective equipment. McDonald continues, “After the Cal OSHA people went back to Sacramento, they had a few follow-up questions about the ropes and about how to test the aerial device. We addressed their concerns and included the information in the variance,” says McDonald. where it stands now With the initial review of the variance complete, SCE is ready to begin training its line workers, as soon as work schedule allows – probably in October or November of this year. By the end of the year, SCE will also develop a prioritized work schedule. The utility plans to begin bare-hand, live-line work in January or February of 2015. Carbajal stresses, “In this case, time is not an issue: safety is our first priority. We are trying to cross every ‘t’ anddot every ‘i.’ We want to be sure that we have the right products and the right training before we begin this work. Our employee’s safety is paramount.”

In rebuilding a 14kV substation in El Paso, Texas in late fall 2013, El Paso Electric found something quite extraordinary: a 71 year old Fargo ® parallel groove clamp. “I collect antique electrical parts,” said Salvador Gonzalez, the lineman that found the connector, “so I knew it was old.” Gonzalez sent the clamp back to Hubbell Power Systems in Leeds, Alabama where the age was verified. Not only was this elder clamp still in service, but it would have remained in service had the substation not been rebuilt. “I attest the clamp’s duration to the quality of howproducts used to bemade. The clampwas made out of copper, which is less prone to expand and contract with temperature,” remarked Gonzalez.

“although we’ve simplified some parts in our clamps, they are virtually made the same way today as they were when this clamp was manufactured.”

Did you know that surge arresters are designed towithstand many lighting surges and survive?

We do. A common industry misperception is that an arrester fails and needs to be replaced after diverting a lightning surge. Our Metal Oxide Varistors (MOV) are part of our core technology at Hubbell Power Systems - unlike many other manufacturers who do not produce their own MOV blocks. We continue to drive this technology forward with strict control of MOV quality and performance.

Hubbell Power Systems, Inc. has over 30 Million distribution arresters in service with less than an 0.02% failure rate, providing critical protection, longer.

Minimizing Outages by patricia irwin, PE

In an industry driven by performance

indices, minimizing the size of an outage

is vital. Alabama Power does this by adding

interrupting devices to the lines.

HUBBELL POWER SYSTEMS | 11

“Just like everyone else, we’re driven by SAIDI, SAIFI, MAIDI, and MAIFI. So, we’re taking a hard look at our systemand figuring out what we can do to improve those numbers,” points out Robert Cheney, Team Leader of Test Lab, Alabama Power. Strategy The most obvious approach is to add fuses, reclosers and switches to the line, but there are limits to the number and types of devices that can be added. Sectionalizers are another option and they can provide a number of benefits to a utility. Fuses: Consider the simplest of line interrupting devices: The fuse. They are inexpensive anddo not require any special training to replace, but have limitations when used as a sectionalizing device. If a line has a 40-amp fuse, downstream from a 70-amp fuse, downstream from a 100-amp fuse, the appropriate fuse(s) should blow in response to a fault current. But if the short circuit is too high, they are all going to blow, cutting power to many meters. Reclosers: For time coordinated devices, like reclosers, there are are a number of timing issues to consider. First, there is a little bit of error in the timing of any device. Second, there is mechanical operating time (the interval between tripping-initiation and fault clearance) to consider, as well. John Thorne, Senior Engineer, Alabama Power explains, “Let’s say you allow 160 milliseconds for operating time of a single recloser. If I have three reclosers strung out along a line, those times add up. The first only needs 160ms to operate. The second needs 320 ms and the third needs 480 ms to operate. That’s half of a second. Back at the substation, you have to decide how long a transformer can safely experience a fault current before the breaker should trip. If I set the breaker to operate after one second and each device takes 0.16 seconds, there are only so many devices that I can fit under that one second time limit.” ALTERNATING SECTIONALIZERS & RECLOSERS aLaBaMa POWeR, see previous page

At Alabama Power, line devices and protection schemes can usually handle three or four, time-coordinated devices on a feeder, while still maintaining proper separation between the tripping curves. However, if you use a combination of both sectionalizers and reclosers you can add more devices to the line. Sectionalizers: Thorne continues, “A lot of times we would prefer to install a time-coordinated interrupting device, but we can’t because we need to maintain an acceptable separation between the operating curves. A sectionalizer allows us to add more devices.” The Alternating Approach A sectionalizer has to open while the line (or line section) is de- energized. If you have a recloser just outside a substation and three sectionalizers downstream, you have to coordinate the four devices so the furthest sectionalizer opens during the first recloser operation. The second sectionalizer opens during the second recloser operation and the closest sectionalizer opens during the third recloser operation. Cheney has a better idea. “Outside of the substation, we put in a recloser and a sectionalizer that is programmed to open during the third open interval. This provides two opportunities for the line to clear temporary faults, before the sectionalizer operates.” “Further out we install another recloser, and then another sectionalizer. Those twosectionalizers arenot directlyunderneath each other, so we can maintain that third-open interval operating characteristic. By alternating sectionalizers and reclosers, we can double the number of devices on the line,” continues Cheney. In this arrangement, there is no opportunity to automatically clear a temporary fault. So, it is not a great plan, either.

The Advantage “We have a lot of reclosers, fuses, and sectionalizing devices to help keep our line segments small. At the end of the day, we do it to reduce the number of customers that are affected by any one outage,” says Thorne. Wheredoes thisarrangementworkwell?Just abouteverywhere. Thorne explains, “it’s not necessarily a long or short feeder solution. We use this configuration on feeders that branch frequently. Our distribution system looks like a spider web. At every single intersection there is a split or fork and the line goes here and there. Those are the feeders that are candidates to have a lot of devices on them.” Alabama Power tries to limit the number of customers on each device to about 500, where it can. This is no small task, since the utility (headquartered in Birmingham, Alabama) provides electricity to 1.4 million customers. Decide Where Finding a good place to add a sectionalizer is often easy. Cheney explains how to do it: “If you look at the feeder map, you can see places that look like a good spot to stick a sectionalizer. Branching feeders make good locations but geography is also important. If there’s a river or impediments that a repairman would have to drive a long way to get around...that is also a good spot.” Like other utilities, Alabama Power also looks at the indices for its feeders. Every feeder is ranked, based on performance, and money is appropriately allocated. Outages Alabama Power experiences its share of outages. Many are caused by lightning, but the primary cause is animal outages. “Down here in the south, we have these things with four little legs and a bushy tail. It is amazing what a squirrel can tear up. And, we have enough animal related problems that ‘Possum’ is a valid code in our outage management system,” expounds Thorne. Single and Three-Phase Sectionalizers The utility has been using Hubbell Power Systems’ single-phase sectionalizers for the past 15 years. And it has just started installing Hubbell’s three-phase units as well. The utility has over 500 single-phase sectionalizers on its system. It only recently started installing Hubbell’s three-phase units but plans to add more. Cheney points out, “In the past, we used another vendor’s three- phase sectionalizers, but they quit making the 200 amp model. The only alternative they offer is a 400 amp sectionalizer. So, we went with Hubbell because the device does what we need it to do and we’ve had a good history with Hubbell. They are especially good when it comes to technical support.”

(Alabama Power has relatively high, short-circuit currents on its system. It is a densely populated area and the substations are closer together. The utility’s short-circuits currents are typically in the 2,000 to 3000 amp range.) Alabama Power typically uses three, single-phase sectionalizers on a three-phase circuit, but it depends on the situation. “Sometimes we need a three-phase device to avoid single phasing a customer. In that case, we use the Hubbell’s three- phase sectionalizer,” says Cheney. Most of Alabama Power’s large, commercial customers are served by a 2,000 to 2,500 amp padmount transformer. The bayonet fuses in those transformers will not coordinate with upstream line devices. So, the utility often uses a sectionalizer to help with coordination. Cheney adds, “we can put a fuse on the risers because it would have to be smaller than the bayonet fuses. We like to have our underground system protected or at least be able to disconnect it if there is a fault. Reclosers are expensive. And we can’t use fuses because of the size. So the only thing that’s left really is a sectionalizer.” According to Thorne, “the three-phase device is desirable from a price standpoint and it is an appealing addition for medium- sized pad mounted transformers for our industrial customers. When our engineers want to provide the customer some type of three-phase protection, Hubbell’s three-phase sectionalizer is significantly cheaper than the other options.” The utility also has problems with ferro-resonance, which can occurwhena three-phase load is servedbyaY-Delta transformer. If you lose one phase of the line, the neutral can shift on the Delta side. “It doesn’t happen a lot, but when it does, we don’t want to smoke our customer’s motors,” says Cheney. We have a lot of reclosers, fuses, and sectionalizing devices to help keep our line segments small. At the end of the day, we do it to reduce the number of customers that are affected by any one outage.

Cheney continues, “The three-phase sectionalizer is another tool we can use. It gives our engineers a little more flexibility.”

Fiber Storage a r e yo u d o i n g i t w r o n g ? In the early years of fiber optic cable storage, linemen had no reasonable way to store cable other than to simply coil it up on the line and create a “rats nest”. This method leaves the cable vulnerable to the elements and creates a tendency for the cable to migrate. Contractors were constantly revisiting these ineffective storage locations and wasting valuable time and money trying to correct an issue that could be solved with proper planning. Utilities and communications construction companies often make financial cutbacks on the front end of a project, only to find out that conservatism causes higher costs on the back end. After concluding projects, Project Managers realize that those expensive corrections could have been avoided if the right products and procedures had been used to facilitate a clean and safe cable environment. Now, storing, installing, and maintaining cable in a cost effective way is easy. Instead of using financial shortcuts on the front end of a project, engineers are now opting for a more economical way to store fiber in a manner that keeps it protected, thus saving money overall.

In Alaska, the 115-kVQuartz Creek transmission line connects two hydroelectric dams on the Kenai Peninsula with the ‘rail-belt’—an area containing Alaska’s railroad, its most populous cities and about three-fourths of the state’s population. A fifteen mile section of that line was rebuilt last November, in an area where snow storms regularly drop feet of snow throughout the winter. While not a technically challenging project, Hubbell Power Systems TowerPak ® solution was a great benefit. The hardware arrived on time, properly kitted and… nothing got lost. This is a big deal when you are working in a snowy mountain pass in Alaska in the winter. The Quartz Creek line is 90-miles long and is operated by the state’s largest electric utility—Chugach Electric Association, based in Anchorage, AK. Shawn Wendling, senior project manager, explains thesituation. “The linewasoriginallybuilt in 1962 to connect the Cooper Lake Dam to the rail-belt. In 1991, the state brought online the substantially larger Bradley Lake Hydro Project, which also uses the line. The Quartz Creek line is critical because it is the only transmission line connecting the two dams to the rail-belt and because that generation is our cheapest source of power. It is also important because we use our hydro resources to adjust for system variances, so that gas consumption at our combustion turbines stay on schedule.” The line and its structures are now over 50 years old and the cooperative keeps an eye on structure integrity. In 2007, Chugach performed a detailed helicopter survey, which revealed some deterioration of the wooden, H-frame towers. The cooperative then verified the damage with a climbing survey. “During the summer of 2008, we sent crews down the right-of-way and tested the arms and poles. About 50% of the poles surveyed showed signs of rot,” explains Wendling.

opti-loop ™ FOs features

Some units can be stacked for even more versatility Sizes that will accommodate all types of cable up to 1.50" multiple sizes versatility materials lightweight

Offered in aluminum and plastic made of polypropelene containing UV inhibitor

Compact and lightweight to minimize stress and ice loading on the fiber cable

Installation of the OPTI-LOOP ™ system is designed to be a one man, one tool, one truck, 30-45 minute operation. The stored length of cable can be lowered and reinstalled in minutes without disturbing the main run. The reduced cost associated with hardware, labor and equipment saves time and money. STORAGE REEL In some regions, cable storage is attempted with a device as shown in Figure 1.1. At first glance, this product seems to justify itself by essentially providing a storage area, as opposed to simply “looping” cable on a line. However, this method leaves the cable exposed and potentially hazardous, costing an exorbitant amount in repair and lost service time. OPTI-LOOP ™ FOS SOLUTION The benefits of fiber storage loops havemade thema preferred industry method for storing and protecting reserve lengths of lashed fiber and ADSS fiber. Hubbell Power Systems’ OPTI- LOOP ™ Fiber Optic Storage (FOS) solutions are the standard for aerially storing and protecting fiber optic cable in the field. OPTI-LOOP is neatly stored, and there are no coils, boxes, “arm” assemblies or unsightly cables running down the pole. They provide a convenient and safe splice closure mounting point because splice closures are mounted directly to the dead-end hardware, keeping it neatly secured with no load on the fiber cable. OPTI-LOOP is approved for use in both the communication and supply regions of the pole. There is no limit on amount of cable that can be stored, and they can be used on wood, steel or concrete poles.

CABLE TWISTING This “garden hose” method of storing cable encourages cable twisting, which results in attenuation and diminished signal strength. The preferred method of storage needs to address this concern and enable a safer method that will prevent twists in the fiber sheath when the cable is retrieved for later use.

CABLE PINCHING

Notice the way that the cable is installed on the device in Figure 1.1. Tie wraps are directly attached to this large bundle of cable. When this method is implemented, it pinches down on the cable causing damage to fragile fibers. Similar to twisting, the result is attenuation and lost signal to the customer. Cable needs to be stored in a way that

figure 1.1

minimizes contact with tight tie-wraps so that no pinching occurs. If cable is nestled into a channel (see Figure 1.2) and the tie-wraps cover the surface of the storage device as opposed to direct contact with the fiber, pinching is completely avoided.

By tightly coiling cable in a device that isn’t engineered to protect specific sizes of cable, all of the previouslymentioned factors (twisting, memory, stress, etc.) can become a huge problem on your line. Additionally, those tender fibers will likely be broken. SPLICING Every fiber cable storage scenario must consider that one day, that particular cable will need to be revisited for service and/or splicing for new builds. When it’s time to add new lines, splicing is one of the most expensive tasks. When systems are installed in ways that don’t take future splicing into consideration, new problems arise. By storing fiber aerially on the line with reserve cable protected, splicing can be simplified. AESTHETICS Large coils of fiber on a pole are an eye sore and get in the way of a lineman working at that pole. Storing the cable safely on a line creates a much more pleasant appeal. By storing cable in a Figure “8” storage pattern, it prevents twists in the fiber sheath when stored cable is retrieved for use. The fiber resists attenuation and it will prevent outages resulting from damaged cable. The plastic direct-attach models of OPTI-LOOP units contain minimal conductive materials, and therefore may be used above ground neutral. Standards engineers use OPTI-LOOP to help eliminate fiber optic cable storage problems.

CABLE MEMORY Because of its construction, cable has a natural tendency to take on the shape to which it’s molded. When cables are stored in a tight coil, uncoiling affects the cable memory. When contractors try to re-straighten that line, the tiny optical fibers have a tendency to migrate. An alternative method of storing cable would preserve cable memory by allowing the cable to bend naturally according to the outside diameter. CABLE STRESS When cable is stored in a method that does not support and protect it, cable stress occurs resulting in broken fibers and diminished or interrupted signal. It’s always best to store cable inside a protective channel (Figure 1.2) so that you create a smooth transition to the messenger. An outward or inward facing channel also safely and securely protects cable from direct contact with harsh weather elements. APPROVAL. IT’S IMPORTANT Always be sure your method of storing cable is approved for use by the manufacturer of that cable. Otherwise, when damage occurs from using ineffective methods of storage, the warranty will be void. BEND RADIUS One-size-fits-all is never a good rule of thumb when storing cable. Bend radius is a real, ever-present issue that must be observed in order to protect the integrity of the cable.

How do you see the telecom industry changing in the next 2 years, and how does your company plan to stay ahead of the curve? In addition to the incoming customer information, we spend a significant amount of time reading industry trade publications, industry standard committee notes and talking with parallel industry suppliers about what’s next. My role at HPS is to eval- uate the data and manage new product development projects so that HPS will have products that are relevant keeping us ahead of the technology curve. Our internal product develop- ment and acquisition related activities are focused at helping HPS build our product portfolio so we can offer the market relevant products that are needed for building next generation networks. Where do the great ideas come from in your organization? Tell us about an innovative solution you and your company developed to solve a non-traditional problem. Our great ideas come from listening and communicating with customers. Our team is using an innovation strategy called Need-Seeker, which focuses development efforts on anticipat- ing future market needs through better understanding our customers’ applications, and the challenges they routinely encounter. A recent example is a customer who wanted a universal antenna bracket for small cell applications. Once they approached Hubbell with the need, we assembled a team, held regular calls, and conducted on site meetings with them for the purpose of mapping out which features were important for small cell applications. I spent time with the radio frequency engineers who really helped us better understand antenna placement. Our team collaborated with several antenna manufacturers and cable assembly suppliers, which led to designs with modularity and cable routing features to help the construction crews. All of the great ideas originated from communication with our customer and parallel suppliers for this small cell bracket project, which solved their problem and answered market needs.

What does it mean to be innovative?

It means finding a better way. Being innovative is in our DNA at Hubbell Power Systems. Our company founders were inventors like Harvey Hubbell, who invented the electrical plug and pull chain light socket and Albert Bishop Chance, who invented the first practical earth anchor that we still use today to secure poles. I am fortunate to work with a team that continues building on the legacy of developing innovative products to help our customers solve problems and improve their network installations. Our sales and engineering team listen to our customers and spend time learning about our customers’ applications. We share our ideas on possible solutions with our customers and make adjustments based on their feedback. Innovative ideas come frombeing collaborative and responsive to our customers and helping them find better solutions. As new product development opportunities come up, our sales team and I are listening our customers trying to deter- mine the scope of the project and what resources will be required for a successful outcome. It is easy to get caught up in the excitement during customer conversations with new opportunities so it is important for us to keep our emotions in check and stay focused on getting the relevant data to determine if the project is going to be viable. One given is there will always be a some level of uncertainty and risk for each project we take on. The key to making a good decision is to trust your intuition. You have to trust your training and past experiences to guide you and not allow fear of failure to drive your decision making. What are the most important decisions you make as a leader of your organization? With network evolution technologies moving so quickly, how do you and your company plan to stay relevant? We are fortunate at HPS to have a skilled and experienced field sales team who does an outstanding job at position- ing themselves as the “go to guys” with our customers. The HPS sales team has created a situation where our customers are continually coming to us with new product develop oppor- tunities. My challenge is to identify the best fit opportunities that will bring the best results for our customers and help grow HPS’ market share.

Talk about small cells and your company’s role in that area.

The US added 12 million new wireless subscribers in 2013 with the majority being non phone devices. Mobile data accounted for 4% of revenue for wireless carriers in 2004. In Q4 2013, mobile data accounted for 50% for the first time. Small cell growth is driven by consumers who are connecting more devices to their carrier’s networks while demanding faster data rates. HPS’ product focus for small cell is building antenna brackets. We believe there is tremendous upside for these product lines.
