Power cables are cables used for transmitting and distributing electrical energy. They are commonly used in urban underground power grids, power station outgoing lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seawater In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system, including various voltage levels of 1-500KV and above, and various insulated power cables The basic structure of power cables consists of four parts: core (conductor), insulation layer, shielding layer, and protective layer

Folded core

The core is the conductive part of a power cable, used to transport electrical energy, and is the main part of the power cable.

Folding insulation layer

Insulation layer is an indispensable component in the structure of power cables, which electrically isolates the wire core from the ground and between wire cores of different phases, ensuring the transmission of electrical energy.

Folding shielding layer

Power cables of 15KV and above generally have conductor shielding layer and insulation shielding layer.

Folding protective layer

The function of the protective layer is to protect the power cable from external impurities and moisture intrusion, as well as to prevent direct damage to the power cable by external forces.
