This product is a new generation replacement product developed by our company for the protection weakness of all kinds of current overvoltage protectors, which is specially used in 35KV and below medium voltage power grids. It is mainly used to protect the insulation of electrical equipment such as transformers, motors and shunt compensation capacitors from overvoltage damage. This series of products can effectively limit atmospheric overvoltage and all kinds of vacuum circuit breakers caused by the operation of overvoltage, phase and relative to the ground can play a reliable limiting role, the product is in line with the national industrial policy and national electrical products oil-free, miniaturization, energy saving and environmental protection trends, with significant technical and economic benefits and extensive social benefits. Widely used in power plant, transformer (distribution) power station, metallurgy, petrochemical, mining, construction, environmental protection and other fields of electrical equipment protection.
