Power cable is a cable used to transmit and distribute electric energy, power cable is often used in urban underground power grid, power station lead line, industrial and mining enterprises internal power supply and cross-river and seawater transmission lines.

In the power line, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the backbone line of the power system, including 1-500KV and above various voltage levels, various insulated power cables.

The main advantages

1 occupies less land. Generally buried in the soil or laid indoors, channels, tunnels, the insulation distance between the lines is small, no pole tower, occupy less land, basically do not cover the surface space.

2High reliability. It is affected by climatic conditions and the surrounding environment for small reasons, and the transmission performance is stable and the reliability is high.

3 has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cables, etc.

4The distributed capacitance is larger.

5 Maintenance workload is small.

6 Electric shock is less likely.
