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
–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.

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.
In addition, the cables are usually heaped
and tend to get hot, adversely affecting
their carrying capacity and causing them
to age more quickly.
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 2.5mm2 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.
