Product Description

The lightning arrester is the basis of insulation coordination of all kinds of electrical equipment in the power system, and the internal and external insulation indicators of all electrical equipment in the power system are determined by the protection performance of the lightning arrester (short-time power frequency voltage withstand, lightning impact voltage withstand and operating impact voltage withstand, etc.).

Metal oxide demand avoider, commonly known as "zinc oxide lightning arrester", the product's working components are made of zinc oxide based multi-metal oxide powder, with excellent nonlinear volt-amperage characteristics, fast steep wave response, large flow capacity. The product with gap adopts self-blowing gap and equivoltage irradiation structure, which reduces the dispersion of discharge and has small impact coefficient.

The use of composite insulation jacket conforms to the development trend of miniaturization, safety and maintenance-free of international power products. Compared with traditional inorganic materials such as ceramic and glass, polymer organic composite has the advantages of small size, light weight, anti-fouling and anti-cleaning, explosion-proof and shock-proof.
