Low voltage polymeric zinc oxide arrester distribution lightning
arrester surge arrester from factory
Features
Small size, light weight, collision resistance, no loss during
transportation, flexible installation, especially suitable for use
in switch cabinets
Special structure, integral molding, no air gap, good sealing
performance, moisture-proof and explosion-proof
Large creepage distance, good water-adding ability, strong
pollution resistance, stable performance, and reduced operation and
maintenance
Unique formula of zinc oxide resistor, high capacity, low leakage
Application
Zinc oxide arrester is mainly applied to line protection fr transformer, cable
connector and other electrical equipment in power transmission and
distribution system. It can help from being damaged by lightning
impluse voltage and over voltage.
