The most original arrester is the lamb horn gap, which appeared in the late 19th century. It was used for overhead transmission lines to prevent the equipment insulation from being damaged by lightning and resulting in power outage, so it is called "arrester". In the 1920s, aluminum arresters, oxide film cangzhou.89ix.comshiyanjiw.89ix.comshoubanhulu.07858.netdianbiaox.37ix.com.cnzengbaiji.37ix.com.cn

Modern high-voltage arresters are not only used to limit the overvoltage caused by lightning in power system, but also to limit the overvoltage caused by system operation. There are two types of lightning arresters: tube type and valve type. Valve arresters are divided into silicon carbide valve arresters and metal oxide arresters (also known as zinc oxide arresters).
