The use of the power cable has been more than hundred years history. In 1879, an American inventor T.A. Edison surrounding the jute and wear it on copper bar into the iron pipe, and then fill the asphalt mixture made cable. He will this cable laying in New York, created the underground transmission.

Power cable is used for transmission and distribution power cable, power cable is often used in urban underground power grid, power stations, which leads to the line, industrial and mining enterprises, internal power and jianghai underwater transmission line.

In the electric power line, cable proportion is gradually increased. Power cable is in the trunk line of the power system for transmission and distribution power electricity cable products, including 1-500 kv and above all kinds of voltage grade, all kinds of insulated power cable.

According to the voltage are rated

According to the voltage level can be divided into the medium and low voltage power cables (35 kv and below), high voltage cable (110 kv) and ultra-high voltage cables (275 ~ 800 kv) and ultra-high voltage cable (1000 kv and above). In addition, it can be divided into ac and dc cable in the current system.

Low voltage cable: suitable for fixed installation in ac 50 hz, rated voltage up to and including 3 kv power transmission and distribution lines for transmission of electricity.
