About AC Power Cords

AC power cords carry alternating current from one area to another. There are many different standard plugs and voltages, depending upon the country. These cords are a conducting medium, usually copper, that is surrounded by insulation and a jacket. Power cords can have 2, 3, or 4 conductors. Choices for male end types include NEMA types, hardwired stripped types, hard wired terminals, CEE, BS, JIS, AS, SRAF, SEV, CEI, SI, and BS types. The National Electrical Manufacturers Association (NEMA) sets standards for AC power cord male ends. The male end can also be stripped hard wires, hard wires with terminals, European ends, UK specific ends, and many other country specific types. The polarization for male end types can be polarized or no polarized. A polarized end fits only one way; a no polarized end fits both ways. Female end types include NEMA, hard-wired stripped, hard-wired terminals, and IEC types. The National Electrical Manufacturers Association (NEMA) sets standards for AC power cord female ends. The female end can also be stripped hard wires and hard wires with terminals. The International Electro technical Commission (IEC) sets standards for European female ends.

Products & Services Related to AC Power Cords

AC Power Connectors

AC power connectors transfer alternating current through a variety of electronic devices. AC power connectors include simple AC inlets, outlets, and power entry modules.

Cable Assemblies

Cable assemblies are collections of wires or cables banded into a single unit with connectors on at least one end.

Cable Protectors

Cable protectors cover wires, cables, hose or pipe in high traffic areas to protect them from damage.

Cable Ties

Cable ties hold groups of cables together for support and ease of maintenance.

Cable Transits

Cable transits are bulkhead or barrier modules that allow electrical cables to pass through, while providing various levels of sealing, strain relief, and damage protection, depending on the application requirements.

Cable Trays

Cable trays are rigid-type trays used as raceways for cables and wires.

Coaxial Cables and Triaxial Cables

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.

Coiled Cords and Cables

Coiled cords and cables consist of a wire wound around a tubular axis. The result is a spring-like form that is able to stretch and bend with minimal stress on the wire.

DC Power Cords

DC power cords are electrical cables that are used to connect two DC devices or a DC device and a DC power source. They are also known as DC power cables.

Flat Cables

Flat cables are typically used in computers for internal connections to peripherals. They are also referred to as ribbon cables.

Multiconductor Cables

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.
