About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Continuous-Flex Power Cable

Shielded

Power motors on moving gantries and cranes with this cable that flexes millions of times without breaking. It’s made for constant motion, with finely stranded conductors twisted like a rope to resist wear from bending.

Shielded—Shielding stops these cables from acting as antennas that emit electromagnetic interference, which could disrupt nearby equipment such as control or data cables.

DLO 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 outer 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.

UL 2556 FT4—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.

Aluminum Building Wire

Mend or extend aluminum wire often found in older buildings. This wire isn’t recommended for new wiring, since it’s more likely to overheat than copper when conducting electricity. However, it’s safer to maintain existing aluminum wire with aluminum rather than mixing materials. Building wire is also known as branch circuit wire.

This wire has an outer layer of nylon insulation that won't degrade from oil and water. It’s designed to be pulled through conduit without pulling lubricants. THHN and THWN-2 designated, this wire can be used in damp places.

High-Current Pin-and-Sleeve Power Cords

Send power from generators to keep the lights on and equipment running. These cords are often used to convey temporary power during outages or at trade shows and mobile job sites. Able to send currents above 250A, they’re commonly connected to power distribution panels and transfer switches. Push and twist to lock them in place, where they remain secure against high current loads, vibration, and pulling. They don’t require tools to connect or disconnect, making them convenient for short-term setups.
