[0002] Power cables are cables used to transmit and distribute electric energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Its basic structure consists of four parts: core (conductor), insulation layer, shielding layer, and protective layer. The core is the conductive part of the power cable, which is used to transmit electric energy and is the main part of the power cable. The insulation layer electrically isolates the core from the ground and the cores of different phases from each other to ensure the transmission of electric energy. The shielding layer is usually used for power cables of 15kV and above to improve the electric field distribution inside the cable. The protective layer is used to protect the power cable from the intrusion of external impurities and moisture, and to prevent direct damage to the power cable by external forces.
