Power cables are Guangxi cables used to transmit distribute electrical energy. Power cables are often used in urban underground power grids, power station leads, internal power supply in industrial mining enterprises, underwater transmission lines across rivers seas.Guangxi cable manufacturer
Power cable classification:
1. According to the voltage level
According to the voltage level, it can be divided into medium low voltage power cables (35kV below), high voltage cables (above 110kV), extra high voltage cables (275-800kV) UHV cables (above 1000kV). In addition, according to the current system can also be divided into AC cables DC cables.
2. According to insulating material
(1) Oil-impregnated paper insulated power cable
Power cables insulated with oil-impregnated paper. Its application history is the longest. Safe reliable, long service life cheap. The main disadvantage is that laying is limited by drops. Since the development of drip-free paper-impregnated insulating materials, the drop limit problem has been solved, allowing oil-impregnated paper-impregnated cables to continue to be widely used.Guangxi wire cable
(2) Plastic insulated power cable
Power cables with extruded plastic insulation. Commonly used plastics are polyvinyl chloride, polyethylene cross-linked polyethylene. The plastic cable has the advantages of simple structure, convenient manufacture processing, light weight, convenient laying installation, is restricted by laying drop. Therefore, it is widely used as medium low voltage cables, has a tendency to replace sticky-impregnated oil-paper cables.
(3) Rubber insulated power cable
The insulating layer is made of rubber various compounding agents. After fully mixing, it is extruded wound on the wire core, it is formed by heating vulcanization. Soft elastic, suitable for frequent movements, with a small bending radius.Guangxi cable
