Aerial insulated power cables can be used for transmission and distribution lines with rated AC voltage 1kv-35kv
Aerial cable is used for overhead power transmission and distribution lines with the voltage from 1KV-35KV.Also can be installed in the street with dense trees close to the building site of urban construction.
It consists of copper or aluminum conductor,inner shidleing layer,weather-poof indulation material and outer shidleing layer.It has not only power-transmitting chatacter of power cable,but strong mechanical chatacter of aeria; cable as well,In compaison with bare,It boasts many advantages such as small span in laying the initiative to choose to use.
