Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield. Triaxial cables are specialized coaxial cables.
Hookup wires are used in low current, low voltage (under 1000 V) applications within enclosed electronic equipment. They are also used in control panels, meters, computers, business machines, and appliances.
Multiconductor cables contain two or more conductors, each of which consists of a single wire or combination of wires. Cable shielding is placed around an insulated conductor or group of conductors to prevent electrostatic or electromagnetic interference between the enclosed wires and external fields.
