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.

Servomotor Continuous-Flex Cable

Connect servocontrollers and servomotors in automated equipment and on assembly lines. This cable withstands continuous motion without degrading data or signal transmission. The polyurethane rubber insulation resists abrasion and oil. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material.

Power Wire—Stranded


Double Shielded

Cable with power wires sends electricity to run a servomotor.

Double Shielded—Double shielded cable has a layer of braid and foil shielding for better protection against signal interference than braid alone. Use it in environments with high signal distortion, such as near transformers, generators, and heavy duty motors.

Bend Radius—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.

Harsh-Environment Power Cable

Type P Cable

Type P Cable with Bronze Armor

Transmit power in dirty, corrosive environments such as offshore rigs and ships. This cable is strong enough to resist crushing forces from heavy equipment. Its CPE jacket and tin-plated copper conductors maintain power in areas exposed to chemicals, oil, and salt water. It meets UL 1309 for high-performance marine cables, yet works just as well on land.

Bronze Armor—A layer of bronze armor between the two outer jackets boosts resistance to abrasion, impact, and crushing.

Variable-Frequency Drive Motor Cable

This cable is used in variable-frequency drive motors. It has a layer of braid and foil shielding that provides excellent protection against signal interference caused by voltage fluctuations and current spikes. The industry designation is WTTC, so it can be installed in cable trays or raceway in a wind turbine generator. It’s flame rated FT4 to meet requirements for preventing the spread of flames based on a timed test with material mounted to a vertical tray. The insulation resists oil.

No-Conduit-Required Continuous-Flex Control Cable

Unshielded

Shielded

Eliminate the need for conduit and cable splices. Made to TC-ER (Tray Cable, Exposed Run) standards, this cable resists impact and crushing force. You can run a single length from stationary equipment to and through moving equipment, such as cable carriers. Support it every six feet to prevent sagging. Even after millions of flex cycles, this cable transmits reliable signals. Its finely stranded conductors are twisted together like a rope, strengthening the cable and preventing fatigue from constant bending.

Unshielded—Choose unshielded wires when electromagnetic interference (EMI) isn't a concern. Equipment such as motors and pumps may have voltage fluctuations and current spikes that distort signals.

Shielded—A single layer of shielding protects sensitive electronics and control systems by blocking electromagnetic interference (EMI). Otherwise, equipment such as motors and pumps could distort signals.

High-Temperature Power Cable

Unshielded

When others can't take the heat, this cable delivers power in ovens, furnaces, steel mills, and foundries. The PTFE jacket won't degrade and weaken as temperatures rise. It also resists abrasion, chemicals, oil, and moisture.

Fiberglass Fabric over PTFE and Mica Tape—A layer of mica tape, naturally heat resistant and electrically insulating, delivers superior protection against high temperatures.

No-Conduit-Required Control Cable

Unshielded

Double Shielded

Made to TC-ER (Tray Cable, Exposed Run) standards, this crush- and impact-resistant cable eliminates the cost and hassle of installing conduit. It’s ideal for exposed runs, such as from a cable tray down to a control panel or motor control box. Support it every six feet to prevent sagging. You can flex and bend this cable during installation and adjustments, but it isn't made for continuous motion.

Double Shielded—With two layers of shielding, this cable offers better protection against electromagnetic interference (EMI) than single-shielded cable. It’s often used near transformers, generators, and heavy-duty motors that may have voltage fluctuations and current spikes that distort signals.

Abrasion-Resistant Continuous-Flex Control Cable

Unshielded

Shielded

Prevent wear and tear in rough areas and conditions. Unlike other continuous-flex control cables, the rugged polyurethane jacket on this cable protects against abrasion as well as exposure to chemicals, oil, and moisture. It’s often used in cable carriers in high-production CNC machines that need reliable signals for millions of flex cycles. Its finely stranded conductors are twisted together like a rope to resist wear from constant bending.
