Modern power cables come in a variety of sizes, materials, and types, each particularly adapted to its uses. We have different types such as
- Low Voltage Power Cables with voltage grade upto 1.1KV used for internal connections & power distribution
- Medium Voltage Power Cables with voltage grade upto 11 KV used for power distribution form the sub station
- High Tension Power Cables with voltage upto 66 KV used for power transmission form power plants
- Extra High Voltage Power cables with voltage grade upto 400 KV used for power transmission of large capacity & longer distances.
Large single insulated conductors are also called power cables. Power Cables consist of three to four major components: conductors, insulation, protective jacket & Steel. 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.
