It is usually an overhead insulated conductor installed on the same pole as the overhead ground wire of the transmission line. It has functions such as lightning protection and communication. The insulated ground wire can reduce the damage caused by lightning strikes to the transmission line, and can also prevent electric shock accidents to a certain extent.

[0011] Preferably, the inner walls of the two rotating grooves are rotatably connected to the outer surfaces of the two rotating blocks respectively, and the cross-sections of the two rotating grooves and the two rotating blocks are both T-shaped.
