Background technique

With the acceleration of urban construction, power cables are widely used in power grid construction, followed by the gradual increase in power cables being damaged by external forces, and the maintenance of operating cables is also increasing. Most of them are laid in parallel. The capacitive effect of the cable causes induced electricity to appear inside the cable during the laying process. The strong induced voltage threatens the personal safety of maintenance and construction personnel. Therefore, there is a need for a line maintenance safety protection device, which is used to effectively ground the cable during the cable construction process, avoiding the induction and electric shock of the construction personnel, and ensuring the personal safety of the construction personnel; It is composed of grounding copper wire, and the insulating rod is fixedly connected with the hook. The grounding copper wire is connected to the tail of the hook with screws. During the grounding operation, entanglement often occurs, and the wiring body is exposed to the outside for a long time, which is prone to aging and leakage. The wiring operation of the ground terminal is cumbersome.
