Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire tighteners, in particular to a wire tightener for electric wire cables. Background Art
[0002] During the power transmission process, we often lay poles to connect wires. At this time, too long lines will lead to a waste of power resources. Therefore, a wire tensioner is often used to tighten the wires. When using it, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm. Use wire clamps to clamp the wire, then turn the special wrench and gradually wind the wire rope or galvanized iron wire around the drum to tighten the wire and fix the tightened wire on the insulator.
[0003] Existing power cable tensioners are overly complex, resulting in easy damage during use, poor operational stability, and inconvenient maintenance. Furthermore, during the tightening process, the wire rope winds slowly around the drum, reducing efficiency. To address these issues, we offer a power cable tensioner. Utility Model Content
