Product Applications
Power cables are cables used to transmit and distribute electrical energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electrical energy in the main line of the power system, including 1-500KV and above various voltage levels, various insulation power cables.

Product category
1. According to the voltage level
According to the voltage level, it can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (above 110 kV), ultra-high voltage cables (275-800 kV) and UHV cables (1000 kV and above). In addition, it can also be divided into AC cables and DC cables according to the current system.
2. According to the insulation material
1. Oil-impregnated paper insulated power cable is a power cable with oil-impregnated paper as insulation. Its application history is the longest. It is safe and reliable, has a long service life and is inexpensive. The main disadvantage is that the laying is limited by the drop. Since the development of non-drip paper-impregnated insulation, the problem of drop limit has been solved, allowing oil-impregnated paper-insulated cables to continue to be widely used.
2. Plastic insulated power cables Power cables whose insulation layer is extruded plastic. Commonly used plastics are polyvinyl chloride, polyethylene, and cross-linked polyethylene. The plastic cable has the advantages of simple structure, convenient manufacturing and processing, light weight, convenient laying and installation, and is not limited by the laying drop. Therefore, it is widely used as medium and low voltage cables, and has a tendency to replace sticky impregnated oil-paper cables. Its biggest disadvantage is the presence of dendritic breakdown, which limits its use at higher voltages.
3. Rubber insulated power cable The insulating layer is made of rubber plus various compounding agents. After fully mixing, it is extruded and wrapped on the conductive wire core, and is formed by heating and vulcanization. It is soft and elastic, suitable for frequent movement and small bending radius.
The rubber materials commonly used for insulation include natural rubber-styrene-butadiene rubber mixture, ethylene propylene rubber, butyl rubber, etc.
3. According to the voltage level
1. Low-voltage cables: suitable for fixed laying on transmission and distribution lines with AC 50Hz and rated voltage of 3kv and below for power transmission.
2. Medium and low voltage cables: (generally refers to 35KV and below): PVC insulated cables, polyethylene insulated cables, XLPE insulated cables, etc.
3. High-voltage cables: (generally 110KV and above): polyethylene cables and XLPE insulated cables, etc.
4. Ultra-high voltage cable: (275～800KV).
5. UHV cable: (1000KV and above).
