[0002] An overhead ground wire is an important component of a high-voltage transmission line structure, is erected at the top of a tower and a conductor, and is a device for protecting an overhead transmission line from lightning strikes and is usually not electrified.

[0003] In recent years, in order to effectively reduce power loss, an overhead ground wire and a tower are connected in an insulated manner, i.e., a two-connection-plate structure double connection. After a long period of operation, due to a high voltage of a conductor, a ground wire induces part of an electric charge, and the ground wire is connected in an insulated manner. If a discharge gap distance is insufficient or damaged, the excess electric charge cannot be effectively leaked to the ground through a tower grounding device, and the two-connection-plate structure is burned by discharge, and in severe cases, even a wire is broken, which leads to a line trip and affects power supply reliability.

The first connecting plate is connected with the tower connecting assembly. The tower connecting assembly is used for connecting with a tower. Each composite insulator is connected with the second connecting plate. The second connecting plate is connected with the strain clamp. The strain clamp is used for clamping a wire.
