    Variable Frequency Drive (VFD) Cable Products

        Norfolk Naval Shipyard brought to the rep’s attention a few ideas to improve our welding cables and lines. TPC picked up the ball and designed products that we now use at the Navy Yard every day.

        THERMO-TREX® VARIABLE FREQUENCY DRIVE [VFD] POWER CABLE, 3 CONDUCTORS WITH 3 SYMMETRICAL GROUNDS

        Designed specifically for the harsh electrical environment of typical variable frequency drive systems, Thermo-Trex® VFD cable features three conductors with three symmetrical grounds, a braided shield, a temperature resistant jacket that provides excellent protection against heat and mechanical abuse in both fixed and motion applications in high heat environments.  The cable is constructed to withstand corona voltages up to 2,000 volts. Symmetrical ground wires are used to reduce the effect of common-mode-voltage noise and the reduction of stray currents.  Ideal for high heat VFD applications where longer lasting cable is desired.
