Thermo-Trex VFD Cable

Thermo-Trex® High Temp VFD Cable

Thermo-Trex® High Temp VFD Cable is designed specifically for the harsh electrical environment of typical variable frequency drive systems that require higher heat exposure and can withstand a maximum conductor temperature of 200°C / 392°F.

This power cable features three conductors with three symmetrical grounds, a braided shield, a temperature-resistant jacket that provides excellent protection against heat and mechanical abuse. The cable is constructed to withstand corona voltages up to 2,000 volts.

Features

FINELY STRANDED NICKEL PLATED COPPER CONDUCTORS

Improves flexibility and extends conductor life in dynamic applications while meeting high heat resistance.

CONDUCTOR INSULATION

Silicone rubber insulation covered by color-coded braided fiberglass yarn impregnated with a saturant to minimize fraying.

THREE SYMMETRICAL GROUNDS

Silicone rubber insulation covered by braided fiberglass. The three core power conductors shall be twisted together with a left-hand lay along with the three ground conductors placed in the interstices of the power conductors with a spiral-wrapped skived PTFE tape cabled as to create a smooth round bundle.

ULTRA-SHIELD CONSTRUCTION

Nickel plated copper wire 34AWG shield to provide 90% coverage with a flat drain wire and spiral-wrapped skived PTFE tape.

THERMO-TREX® HEAT RESISTANT JACKET

Braided fiberglass jacket offers superior protection against heat, abrasion and mechanical abuse.
