Use For:
Unshielded: Motors, Power Supply
Shielded: Motors, Power Supply, Interference Shielding
Flexible
Temperature Range: -20° to 190° F
Insulation:
Outer: Polyurethane Rubber
Inner: PVC Plastic

A thick insulation resists cuts and abrasion, so this cable can be pulled over rough surfaces without damaging the wires inside. Made of polyurethane rubber, the insulation also resists chemicals, moisture, oil, solvents, and water. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Use unshielded cable in applications where signal interference is not a concern.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices. It has an uninsulated ground wire that is not counted in the number of wires.

Outdoor Wire

The EPDM insulation on this wire won’t become brittle or crack from sunlight, humidity, rain, temperature changes, abrasion from dirt and debris, and other rough outdoor conditions. It meets Mine Safety and Health Administration (MSHA) standards for material quality.

SC wire is a good choice for temporary setups powering outdoor lights, equipment, generators, and power distribution boxes, since its thick insulation makes it easy to move and reuse. Commonly found at outdoor events, it’s also known as stage cable.

DLO wire carries higher voltages than SC wire, making it the better choice for heavy duty applications. Use it to run power to motors, cranes, and other equipment in shipyards, mines, and oil- and gas-drilling rigs. Also known as diesel locomotive cable, this wire was originally designed to wire trains. An inner layer of chlorinated polyethylene plastic (CPE) gives it increased resistance to chemicals, heat, and flames. It’s also rated RHW-2, so it can be used underground and in wet locations.

All are flame rated, so they meets requirements for preventing the spread of flames based on a timed test. FT4 wire is mounted to a vertical tray during testing. FT5 wire is suspended horizontally during testing.
