Description

[0001] The present invention relates to a fixing device for an overhead earth wire,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for fixing a geared line compressor, and more particularly, to a compressor fixing apparatus for re-compressing a part of a ground wire to return to a state before damage when a broken wire occurs.

Generally, the transmission tower tower power line is a corridor (2 conductor, 4 conductor, 6 conductor), and it is possible to install a spacer car on the power line, so that 100 ton compressor and various air port are installed in the spacer car when repairing power line. It is possible to repair the used branch line. However, in the case of the ground wire, since the spacer car can not be installed, it is impossible to install the spacer car. Therefore, it is necessary to unfasten the ground wire fixed to the steel towers on both sides of the work area, compress the ground wire by using a 100 ton compressor, So that it takes a lot of work time and unnecessary power consumption of the worker is high and the cost is high.
