AlphaWire Company extends Xtra-Guard® range

–20°C to +90°C for static applications. The cables are available in gauge sizes from 16 AWG to 6 AWG, with larger custom cables available on request. The new range is RoHS compliant, and meets the required safety and installation ratings, including: UL Standard 1277, Type TC-ER, 90°C, • 600 UL Oil Res I • UL Exposed Run (-ER) • CSA AWM I A/B II A/B • UL Standard 1063, Type MTW, 90°C, • 600 Volt CSA FT4 Flame test • UL Direct burial • UL 1581 Vertical tray flame test • UL Sunlight resistant • “Typically the new motor supply range will be used for AC drives and servo motors in applications such as medical, robotic, packaging, welding and conveying, although they are ideally suited to all types of auto- mation environments,” commented Dave Watson, director of engineering at Alpha Wire Company.

The Ecobus flat-cable safety system, on the other hand, can be used to create a very neat, flexible, long-term infrastructure for standard power supply as well as UPS. The system can be attached to the cable conduit systems above the racks using cable clamps. Depending on the energy supply required, Dätwyler offers cables with diameters from 2.5mm 2 to 16mm². The energy can be supplied to or tapped from the flat cable at any point by the means of special adapters, without the cable being interrupted. Connections can be realised via screw or plug type, and wiring can take place even while the cable is live. Email : info@alphawire.com Website : www.xtraguard.com

Alpha Wire Company has extended its Xtra-Guard® product range with the addition of flexible motor supply cables. The latest addition will complement the existing, high-performance, vari- able frequency drive (VFD) product line and is designed for motor and drive applications requiring small outer diameter, flexibility and ease of handling as well as superior EMI/RFI shielding options using the company’s Suprashield®. Smaller, more flexible and less expensive than the VFD cables, the new motor supply range features a round geometry to facilitate environmental sealing, while the symmetrical design improves the electrical performance allowing the cable to exhibit uniform bending characteristics. The cables also employ Alpha’s Suprashield® and have PVC nylon tape, four symmetrical drain wires and a specially formulated oil-resistant PVC jacket for extreme durability in the most demanding of environments. As part of the Xtra-Guard range the motor supply cables incorporate Xtra- Guard’s hazard matched, extreme performance characteristics with an operating temperature range of Economic energy supply to IT cabinets As part of its infrastructure solutions for server and computer centres, Dätwyler Cables offers its Ecobus flat-cable safety system for a comprehensive, flexible energy supply to IT cabinets. The Ecobus system can be easily integrated into all cable conduit systems. The energy can be supplied to or tapped from the flat cable at any point, without the cable being interrupted. Changes can be made while the cable is live. The fuses offer good selectivity and are positioned directly at the end-user terminals. For new installations and extensions, cabling costs are estimated to reduce by up to 80%. By replacing the many single cables with the Ecobus system, the power supply is far more effective and durable. A star topology power supply to IT cabinets, using a number of individual cables, can be untidy and difficult to modify.
