Description

Fixing device to prevent lead wire mixing The present invention relates to a fixing device for preventing lead wire contact. More specifically, the present invention relates to a fixing device for preventing lead wire contact that prevents a power outage from occurring when a lead wire detaches from a power distribution line. In conventional technology, the lead wires of lightning arresters installed on power distribution lines often detach from the lines due to lightning strikes or other reasons. When these lead wires detach, they come into contact with adjacent equipment, causing frequent temporary power outages. In other words, although the lead wire of the lightning arrester is firmly connected to the main body at the time of installation, it often detaches from the main body due to external impacts or weather conditions, and causes a power outage by coming into contact with nearby reinforcing bars and power lines. When these lead wires detach from the power distribution line, they sway up and down or left and right due to their elasticity, eventually settling on crossarms or similar objects, thereby causing ground faults.
