It is usually divided into two methods: hydraulic tightening and spiral tightening. 3.2 Grip clamps are intermediate connecting tools that can automatically clamp wires and facilitate disassembly and assembly when conducting loose and tight wire operations on overhead power lines. They are used to connect wires and traction equipment
