The lightning overvoltage on the overhead insulated lines can extremely easily cause surface flashover or breakdown of an insulator to form a conductive channel. If several hundred KA power frequency follow current arc centralizes on the breakdown point of the insulating layer to cause the melting of wires, and the safety of equipment and people is seriously threatened. In order to avoid lightning-caused breaking accidents, our company has developed the overvoltage protector for overhead insulated lines, and when the overhead insulated line is hit by lightning, the protector can conduct the lightning current and power frequency follow current, avoid the flashover or breakdown of the insulator and avoid the lightning-caused breaking accidents of the overhead insulated lines.
