  • The thread tensioner, also called ratchet tensioner, is used as a tension wire in overhead line laying facilities. When using, first loosen the steel wire rope or galvanized iron wire on the tensioner, and fix it on the cross arm, clamp the wire with wire clamp, and then pull the special wrench. Due to the anti-reverse action of the pawl, the steel wire rope or galvanized iron wire is gradually wound on the ratchet drum to tighten the wire. Fasten the tightened wires to the insulator. Then loosen the pawl first to loosen the wire rope or galvanized iron wire, then loosen the clamp, and then wind the wire rope or galvanized iron wire on the ratchet drum.
