Power cable is used for transmission and distribution of power. Power cable is often used in underground power grid, power station line, internal power supply of industrial and mining enterprises and subsea power transmission line.
In power line, the proportion of cable is increasing.
Power cable is the cable product used to transmit and distribute high-power power in the main line of power system, including 1-500kv and various voltage levels above, and various insulated power cables.

The basic structure
The basic structure of power cable consists of four parts: conductor, insulator, shield and protective layer.
Conductor: the conductor is the electrical part of the power cable, used to transmit electricity, is the main part of the power cable.
Insulation layer: insulation layer is to separate the wire cores from the earth and the cores of different phases on the electrical system to ensure power transmission, which is an indispensable part of the power cable structure.
Shielding layer: power cables with 15KV and above generally have conductor shielding layer and insulation shielding layer.
Protective layer: the protective layer is used to protect the power cable from foreign impurities and moisture, and prevent the power cable from direct damage by external forces.

The main advantages
1. Small footprint.
In general, it is embedded in soil or laid indoors, in channels and tunnels. The insulation distance between lines is small, no poles or towers are needed, and the floor space is small.
High reliability.
Low impact by climatic conditions and surrounding environment, stable transmission performance and high reliability.
3. More favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc.
The distributed capacitance is large.
Less maintenance work.
6 shocks are less likely.
