About Wire and Cable

Wire

Also known as hook-up wire, this wire is primarily used for wiring electrical panels, lighting, and plant floor equipment.

Mil. Spec. Wire

This wire meets stringent military specifications for material quality.

Wire Assortments

Keep spools of wire in multiple colors on hand.

Mil. Spec. Wire Assortments

Maintain a supply of Mil. Spec. wire in multiple colors.

Machine Tool Wire

More flexible than standard wire, this wire is often used for internal appliance wiring and machine tools. Also known as MTW wire.

Abrasion-Resistant Wire

Run power over rough surfaces—this wire has thick insulation that stands up to wear and tear.

Chemical-Resistant Wire

Our most chemical-resistant wire—the PTFE insulation protects against most chemicals, solvents, and oil.

Radiation-Resistant Wire

The PEEK insulation on this wire won't degrade when exposed to radiation, and is often used in nuclear energy production.

Low-Voltage High-Temperature Wire

Rated to 50 volts AC/DC, this wire is often used in small electronics and robotics. It withstands temperatures of 390° F and greater.

High-Temperature Thin-Insulation Wire

With a slim PFA plastic insulation, this wire has the same heat resistance as standard high-temperature wire but its diameter is one-third the size for use in tight spaces.

High-Temperature Wire Assortments

Keep several colors of high-temperature wire on hand with these assortments.

Thin-Insulation Wire

Nearly half the diameter and up to 40% lighter than standard wire of the same gauge and voltage, this wire fits in tight spaces.

High-Voltage Wire

Use this wire in high-voltage applications that require 10,000 volts DC or greater, such as in high-power signs and lasers.

Tangle-Free Wire

Eliminate tangles—the slippery insulation on this wire won't catch on itself, other wires, or on rough surfaces.

Shielded Stretchable Wire

The shielding in this wire blocks signal interference from nearby equipment and devices. When pulled lengthwise, it extends 40% and then returns to its original length, so it's useful for high-vibration applications.

Stretchable Wire

When pulled lengthwise, this unshielded wire extends 40% and then returns to its original length, so it's useful for high-vibration applications.

Cable

Stretchable Cable

This cable can be stretched by about 40% and return to its original length, making it useful for applications where cable is in motion. It's often sewn into garments or used with equipment that must be worn.

Corrosion-Resistant Cable

The insulation resists corrosive chemicals and salt water, and the wires in this cable are tin plated for corrosion resistance.

Ribbon Cable

Often used in electronic prototyping or in the interior of computers, this flat cable is ultra flexible with small-gauge wires so it fits in tight spaces.
