The 6~220kV AC transmission and distribution line suspension composite oxygen oxide surge arrester is connected in parallel to the two ends of the insulator (string), in order to limit the lightning overvoltage of the line, improve the lightning resistance level of the line, and reduce the tripping rate caused by the lightning fault. A new type of arrester that is suspended from a transmission tower.

Our company has applied the technology of producing electric power fittings and composite insulators to the line arrester for many years, and the performance of the products has been greatly improved, and patented, patent number: (200720155561.4).
