technical field

The utility model relates to the technical field of wire tightening devices, in particular to a wire tightening device for electric construction.

Background technique

Wire tensioners, also known as ratchet tensioners, are used for tensioning wires in overhead line laying works. When using, first loosen the wire rope or galvanized iron wire on the wire tensioner, and fix it on the cross arm, clamp the wire with the wire clamp, and then pull the special wrench. Due to the anti-reversal effect of the pawl, the wire rope or galvanized iron wire is gradually wound around the ratchet drum to tighten the wire. Fasten the tightened wire to the insulator. Then release the pawl first to loosen the wire rope or galvanized iron wire, then loosen the wire clamp, and finally wind the wire rope or galvanized iron wire around the drum of the ratchet.
