Electric transmission line drilling method

Номер: CN103972836A
Принадлежит:

The invention provides an electric transmission line drilling method, and relates to the technical field of high-tension transmission lines. When a low-voltage line passes through a high-voltage line in a drilling manner, lightning conductors on electric towers at two ends of a drilling gear of the low-voltage line can be omitted, the distance of a channel in the vertical direction of a drilling line is reduced, and lightning arresters are arranged on the electric towers at two ends of the drilling gear. By using the electric transmission line drilling method, the investment on a body is low, high-voltage-class line outage construction can be avoided, and tower standing positions are not limited.
