In the short-circuit fault process of the 10kV insulated overhead line, the electric force action of mutual attraction or mutual repulsion can be generated between the wires, and the wires can generate torsion deformation. Some torsional deformation exceeds the elastic deformation range, and the original shape cannot be recovered after the electrodynamic force is eliminated. The phenomenon causes the electricity-checking grounding ring arranged on the lead to deflect by taking the lead as a center, and the electricity-checking grounding ring can not be restored to a state perpendicular to the ground, thereby not only affecting the attractive appearance of the circuit, but also adding additional torque to the lead. When the ground wire is hung in the line power-off operation, the torque damage to the wire is larger.
