SOOW—600V AC

Use For: Outdoors, Power Supply
Ultra Flexible
Temperature Range:
Black: -40° to 190° F
Yellow: -55° to 220° F
Insulation: EPDM Rubber

Ultra-flexible cable is good for applications that require tight turns.

SOOW cable has an oil-resistant outer and inner insulation, and water-resistant outer insulation. The EPDM rubber insulation has good tensile strength.

Flame rated cable meets requirements for preventing the spread of flames based on a timed test. FT2 cable is suspended horizontally during testing.

Abrasion-Resistant Cable

Unshielded

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.

Direct-Burial Cable

Use For: Buildings, Outdoors
Flexible
Temperature Range: 0° to 140° F

Weather-resistant insulation makes this cable suitable for outdoor use and direct burial without conduit.

18-gauge wire is often used for sprinkler systems.

High-Voltage Continuous-Flex Flat Cable

Use For: Automation, Continuous Motion
Continuous Flex
Temperature Range: -85° to 325° F
Insulation: Silicone Rubber

Rated to 17,000 volts AC or higher, this cable is often used in oil drilling, robotics, and festoon systems. It withstands continuous motion without degrading data or signal transmission. With a flat shape, it’s good for tight spaces. It meets UL 94 V-0 for flame retardance.

Bend radius is the point to which the cable will bend without being damaged. It is measured from the center of the bend to the edge of the cable. The smaller the measurement, the tighter the bend.

Riser-Rated Communication and Security System Cable

Unshielded

Shielded

Use For:
Unshielded: Buildings
Shielded: Buildings, Interference Shielding
Flexible
Temperature Range: 0° to 140° F
Insulation: PVC Plastic

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

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 is not counted in the number of wires.

Duct-Rated Communication and Security System Cable

Unshielded

Shielded

Use For:
Unshielded: Buildings
Shielded: Buildings, Interference Shielding
Flexible
Temperature Range: 0° to 165° F
Insulation: PVC Plastic

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.

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.
