The basic structure of power cable No matter what kind of power cable, its most basic components are three parts, namely conductor, insulation layer and sheath. For power cables with medium voltage and above, the conductor has high potential when transmitting electric energy. In order to improve the distribution of electric field, reduce the electric field distortion on the conductor surface and the outer surface of the insulation layer, and avoid tip discharge
