Composite insulated metal oxide arrester is an international high-tech product in the 90s, which integrates the excellence of metal oxide arrester and composite insulation material, and becomes the replacement product of the original porcelain sleeve arrester. It is mainly used in power generation, transmission, substation and distribution systems with a voltage level of 0.22~220KV, and is used to limit various overvoltages that may occur to ensure the safe operation of electrical equipment.
It is used to protect power transformers, switchgears, box-type substations, power cable outlets, column oil switches and other power distribution equipment of the corresponding voltage level from damage caused by atmosphere and operating overvoltage.
