Abstract
Description

[0002] The wire tensioner, also known as the ratchet tensioner, is used to tighten the conductor during the installation of overhead lines. When in use, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the conductor with a wire clamp, and then turn the special wrench. Due to the anti-reversal effect of the ratchet, gradually wind the wire rope or galvanized iron wire around the ratchet drum to tighten the conductor. It is used in the fields of power transmission and transformation line tensioning and transport vehicle wire rope tensioning.
[0003] Although the wire clamp head used in the wire tensioner can quickly fix the cable, it can only fix the cable by the friction between the wire clamp head and the cable.
