These cables are used in UPS systems and server rooms as the nylon and fiberglass braid on the cable does not allow the heat generated in the conductor, due to continuous operation, to be felt in the surrounding areas. These cables are widely used in aircraft cabling.
Cable Construction
Annealed tinned copper to IS:10241 Part 3, uniformly bunched to form a circular shape
Special core insulation HR-PVC 105°C
Braided with glass fiber, 100% coverage
Braided with nylon fiber, 100% coverage
Overall construction is finally lacquered with nylon varnish
Properties
Max. Operating Voltage: 600V r.m.s.
Operating Temperature Range: -35°C to 105°C
Resistant to ester-based fluids (hydraulic oil), acids, chemicals, and solvents.
The nylon and glass fibers are very good heat-resistant materials.
