Basic principle of lightning protection for high-voltage transmission line tower arrester: When lightning strikes the tower, part of the lightning current flows to the adjacent towe

Main hazards of icing on high-voltage transmission line towers: (1) The line icing is too thick, the wind area of the conductor increases, the conductor load is easy to break, and t

1. Adjustment of the top angle of the angle steel After the power angle steel tower is inserted into the angle steel, the top angle of the angle steel shall be adjusted immediately.

The transmission line is mainly composed of wires, ground wires, insulators (string), line golden gear, pole tower and pull wires, foundation and grounding device. Witnesses: conduc

Single tube tower is widely used in communication and transmission lines and other fields abroad. Single tube tower has the advantages of simple structure, convenient construction,

Piling characteristics of electric steel pole foundation: 1. The original layout of the original line will not be affected by the in-situ replacement of cement poles for piling; 2.
