About Wire and Cable

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

Power Cable

Built for rough handling and frequent positioning, this cable delivers power you can count on. Use it for everything from extension cords to cords for hydraulic presses. Made to NEC Article 400 requirements, you can trust it to power whatever you need. Plus, the flexible jacket takes the struggle out of routing it through tight spaces and around machinery.

Riser-Rated Communication and Security System Cable

This cable is designated CL3R and CMR, so it has flame-resistant insulation and is approved for use in low-current circuits in vertical shafts and large facilities with multiple levels. It’s often used in intercoms, speakers, and security systems.

Unshielded Stranded Wire

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

Shielded Stranded Wire

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.

Abrasion-Resistant Power Cable

Unshielded

Pull this cable over rough surfaces without damage. The thick polyurethane jacket protects the wires inside and resists wear. It also stands up to moisture, oil, and chemicals.

Duct-Rated Communication and Security System Cable

Also known as plenum cable, this cable is designated CL3P and CMP, so it has flame-resistant, low-smoke insulation and can be used without conduit in duct work and above a drop ceiling. Use it in low-current circuits such as intercoms, speakers, and security systems.

High-Voltage Continuous-Flex Flat Power Cable

For high-voltage systems with constant motion, this cable flexes without breaking. Its thick silicone rubber jacket insulates against high voltage and resists chemicals, oil, moisture, and UV rays. The jacket also has a low-smoke, zero-halogen (LSZH) design to prevent toxic emissions if there’s a fire.
