Rate voltage 1kV and 10kV Aerial Insulated Cable

Aerial insulated power cable consists of copper or aluminum conductor, inner shielding layer, weather-poof insulation material and outer shielding layer. It has not only power-transmitting character of power cable, but strong mechanical character of aerial cable as well, In comparison with bare wire, it boasts many advantages such as small span in laying the initiative to choose to use.
