Applications

These cables are used in UPS systems and server rooms as the nylon and fiber glass braid on the cable does not allows 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

Conductor: Annealed tinned copper to IS:10241 Part 3, uniformly bunched to form a circular shape

Insulation: Special core insulation HR-PVC 105° C

Primary Braid: Braided with glass fiber, 100% coverage

Secondary Braid: Braided with nylon fiber, 100% coverage

Lacquer: 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.
