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 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: Conductors, insulation, protective jacket. The makeup of individual cables varies according to application. The construction and material are determined by three main factors:Working voltage, determining the thickness of the insulation;Current-carrying capacity, determining the cross-sectional size of the conductor(s);Environmental conditions such as temperature, water, chemical or sunlight exposure, and mechanical impact, determining the form and composition of the outer cable jacket.
