About Wire and Cable

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

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.

Unshielded Stranded Wire

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

Access Control Cable

Wire multiple components in your security system using a single cable. This cable bundles together four color-coded cables that correspond to each part of an access point: the card reader, the door contact, the lock, and the exit sign. Each interior cable is labeled with the component it matches. All four interior cables have a layer of foil around them to prevent signal interference from nearby devices. Designated CMP, it has a flame-resistant, low-smoke insulation and can be used without conduit in duct work and above a drop ceiling. It’s also known as plenum cable. It’s rated FT6, so it meets requirements for preventing the spread of flames and smoke based on a timed test with material mounted to a horizontal tray.

Outdoor Lead 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.

2,000V AC

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.

Duct-Rated Ethernet Cords

Also known as plenum-rated cords, these CMP ethernet cords have flame-resistant, low-smoke insulation and can be used without conduit in ductwork and above a drop ceiling. The RJ45 plugs on each end connect to Ethernet equipment, such as computers, IO modules, and programmable logic controllers (PLCs). Not only do these cords transmit data, but they also power devices that are Power over Ethernet (PoE) compatible. They’re often used with EtherNet/IP, Profinet, and EtherCAT systems.

Duct-Rated HDMI Video Cords

Run high-definition signals through duct, above drop ceilings, and below raised floors without using conduit. These cords are plenum rated, so their insulation resists fire and doesn’t produce smoke. Connect these cords to monitors, TVs, and projectors. Each end has both a standard HDMI plug and a micro-HDMI socket, so you can connect multiple devices to the cord at once. The plugs are gold plated to resist corrosion and maintain signals over time.

Note: These cords only transmit signals in one direction. Ends are labeled “Source” or “Display” to help you install the cord.

Duct-Rated Oil-Resistant Ethernet Cable

Unshielded

Also known as plenum cable, this cable is designated CMP, so it has low-smoke insulation and can be used without conduit in duct work and above a drop ceiling. The oil-resistant FEP insulation protects wires as the cable moves from duct to equipment or machinery. It also resists UV light. It’s backward compatible so it works in networks that meet the same or a lower category.
