Since the State Grid Corporation fully implemented the "three collections and five major" system, the provincial company has deepened the construction of the overhaul system, intensively transported and inspected the business, piloted the integration of power substation operation and maintenance, and promoted the centralized maintenance of all or half stations of substations, and the integration of operation and maintenance. With the promotion of modernized business, maintenance personnel not only need to carry out maintenance work, but also need to carry out operation and maintenance operations before maintenance, which brings new challenges to maintenance personnel. In the process of grid power outage maintenance, it is often necessary to hang multiple grounding wires. In order to improve the efficiency and quality of operation and maintenance, it is necessary to design a new device based on high-voltage grounding wires.

At present, most of the grounding wires used in substations adopt the spiral compression operation method. In actual operation, there are the following problems: because the rotation movement of the insulating operation rod is converted into the vertical linear movement of the clamp through the thread, the operator needs to reciprocate a lot. The operator needs to stand on the insulating ladder, raise his hands and rotate dozens of times, which consumes a lot of physical strength and is easy to lose his balance and fall.
