A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed
Power cables are used for bulk transmission of alternating and direct current power, especially using high-voltage cable. Electrical cables are extensively used in building wiring for lighting, power and control circuits permanently installed in buildings.
Electrical cables work by providing a low resistance path for the current to flow through. … The simplest electrical cable may just be a metal conductor – these cables are used as overhead line wires manufactured without any insulating material around the conductor other than the air that surrounds the conductor.
There are many types of electrical cables that differ in configuration, size and performance.
Components of Electrical Cables. All electrical cables consist of at least two conducting wires and an outer protective jacket. …
