Description

Transmission line straight pole overhead ground wire maintenance support

technical field

The utility model relates to an electric power maintenance tool, in particular to a transmission line linear rod overhead ground wire maintenance bracket.

Background technique

At present, in the maintenance of the overhead ground wire of the straight pole of the transmission line, the suspension clamp of the overhead ground wire is replaced, and when the overhead ground wire is replaced, the straight-line upward pulley is mainly fixed on the top of the pole with a wire rope and a wire tensioner.
