Power cable
The basic structure of the power cable is composed of four parts, the core (conductor), the insulating layer, the shielding layer and the protective layer.
Cable for transmission and distribution of electrical energy. Commonly used in the city underground power grid, the lead line of power station, the internal power supply of mining enterprises, over the river, over the sea water transmission line. In power lines, the proportion of cables is gradually increasing. Power cable is the main cable in the power system in order to transmit and distribute electrical energy, including 1-500KV and above all kinds of voltage levels, all kinds of insulated power cable.
According Voltage rating:
1. Low voltage cable: suitable for fixedly installed in AC 50Hz, rated voltage 3KV and below transmission lines for power transmission.
2. Middle and low voltage cable: (general 35KV and below): PVC insulated cables, polyethylene insulated cables, cross-linked polyethylene insulated cables, etc..
3. High voltage cable: (general 110KV and above): PE cable and cross-linked polyethylene insulated cable, etc..
4. Ultra high voltage cable: (275~800 kV).
5. Extra-high-tension cable: (1000KV and above).
Executive standard: GB/T12706-2008
