A power cable is an assembly of two 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. Flexible power cables are used for portable and mobile tools and machinery..
Modern power cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. Large single insulated conductors are also sometimes called power cables in the industry.
Cables consist of three major components, namely conductors, insulations, protection. The constructional detail of individual cables will vary according to their application. The construction and material are determined by three main factors:
Working voltage, which determines the thickness and composition of the insulation;
Current carrying capacity, which determines the cross-section size of the conductors;
Environmental conditions such as temperature, chemical or sunlight exposure, and mechanical impact, which determines the form and composition of the cable jacket enclosing conductors.
