In the operation and maintenance work of the power transmission line, the damage of the insulator is inevitable due to the influence of various factors. The strain insulator string is the most common product of the current transmission line stringing, is used together with a power fitting, and is strung together to reach the requirement of tension according to construction requirements. The insulator is connected with one end of the cable connection through the wire clamping device during installation, a wire at one end is reserved at the tail end of the wire clamp during connection, and the tension of the cable is adjusted by adjusting the length of the reserved wire. When the insulator is replaced, the cable is loosened by shortening the length of the wire, and the insulator falls down and is then replaced. However, in the existing insulator replacement mode, after an operator climbs to a designated position through a telegraph pole, the operator tilts the body, manually holds the insulator, then manually releases a wire, more physical power needs to be consumed, replacement efficiency is affected, and potential safety hazards are increased.
