About Wire and Cable

Motor Cable

This cable is used in variable-frequency drive motors. It has a layer of braid and foil shielding that provides excellent protection against signal interference caused by voltage fluctuations and current spikes. The industry designation is WTTC, so it can be installed in cable trays or raceway in a wind turbine generator. It’s flame rated FT4 to meet requirements for preventing the spread of flames based on a timed test with material mounted to a vertical tray. The insulation resists oil.

Cable with power wires sends electricity to run a motor.

Cable with power and signal wires has an individually shielded pair of wires that connect to a brake or temperature sensor, reducing the number of cables used in areas with limited space.

MSHA approved cable meets Mine Safety and Health Administration (MSHA) standards for material quality.
