When working on a pole and encountering wires with insulated layers, especially if there is no grounding ring at the work site, it is impossible to conduct electrical inspection directly. It can only be performed by other personnel at the transformer inlet and outlet pile heads of insulated wires. It is impossible to confirm again whether the conductor to be connected with the ground wire is live, which increases the safety risk of the operators who are connected with the ground wire on site. Simultaneously, the insulation layer of general insulated conductor has certain thickness, and when hanging ground wire, insulation operation bar only twists by hand friction force, and puncture wire clip sometimes can not puncture conductor insulation layer, can not make good contact.
