Qiaopu power cords and overhead cords more

Voltage power cord is relatively small, the relatively small number of core cords, and overhead cords are high voltage cable, Qiaopu daily production cords and overhead power cord which is the difference?
(1) do not need to set up tower;
(2) help to improve the power factor of the power cord.
(3) Power cord maintenance workload is small, without frequent inspection;
(4) reliable power cord, such as installed in the underground shelter, subject to external damage is small, less chance of failure, security of electricity supply, will not cause harm to the person; In short, the power cord technology content, low cost , voltage and current, safe Reliable.
