Lightning Arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arrester has been designed and type tested according to IEC standard.
Standard.
Metal oxide varistor is the core of the arrester, which main component is zinc oxide and with a small quantity of bismuth oxide, fluoride oxide, manganous carbonate, antimony oxide and other gleam of additive and made with high temperature.
Compared with traditional carborundun, mov(metal oxide varistor)has greatly mended voltage current characteristic and improved through-current capability, thereby to line up protection.
Standard.
Our advantage: we not only produce silicone rubber, but also glass fiber rod by ourselves to assure the quality and best price.
Features of insulator:
1) Silicon Rubber for sheds/ housing
2) Glass-fiber reinforced epoxy resin rod (ECR type) for core
3) Hop dip galvanized cast steel for metal fittings
4) Rated voltage:10KV~220KV
5) 5000hours aging test.
6) IEC Standard.
