What are the characteristics of high voltage power cables
Power cable plays a very important role in our life. It has various types, and the types of products used in different occasions are also different. Qingzhou cable manufacturer today told friends about high-voltage power cables.
High voltage power cable is mainly used for power transmission and distribution, which refers to the power cable used to transmit 1kv-1000kv It is mainly used for power transmission and distribution. Its conductor materials are copper, aluminum, steel cored aluminum stranded wire. When used, the standard is gb/t12706-2008, and the installation temperature is above 0 ℃. It is usually used at normal temperature of 90 ℃.
There are many types of high-voltage power cables. Due to the good conductivity of copper conductors, copper core power cables are used as the main road of power supply system. Aluminum core power cables are less used. Especially in high-voltage power systems, copper core cables are more selected.
The structure of the high-voltage electrical cable is relatively simple, mainly composed of internal and external components, including conductor, insulation, inner sheath, filler and external insulation. At the same time, the armored high-voltage cable can resist the high-strength compression on the ground and prevent other external force damage, so it is mainly used for burying.
