Power cables are conductors designed to transmit and distribute electrical energy. They are used to transmit powerful currents of industrial frequencies from electrical substations, energy and utility companies to switchgear and end users. They are used to power electrical appliances and electrify buildings, structures, residential buildings and even entire cities, regions and countries. They allow connecting stationary facilities and mobile installations. They can be laid underground, in water, at height, or simply laid on the surface.
There are many different classifications of power cables. For example, according to the voltage level, there are models that carry up to 1000 V and cables for high-voltage networks that carry more than 1000 V. According to the method of installation, there are cables for stationary and mobile installations. Cables are also classified according to the number, structure, and flexibility of conductors, conductor alloy, insulation type, cross-sectional area, voltage, and other characteristics. The design of power cables and the form of execution depend on the conditions of installation and the area of application.
