Product Description

5kA Porcelain Surge Arrester

Main principle

ZnO lightning arrester is one kind of most advanced over-voltage protector at present in the world, due to its core components of resistance applying ZnO and other metal oxide to make of comparing with traditional carborundum arrester, it improves greatly V-A characteristics of resistance, increases the getting through ability of resistance, thereby it brings fundamental, change to features of arresters.
Under normal working voltage, the current passing arrester only A class, when bearing over voltage. The excellent non-linear V-A features of arrester would make effect, the current passing through the arrester increase high to thousands of Ampere instant the arrester is under getting through state, to release over-voltage energy therefore it errective limits the demage to power transmission equipments due to over voltage.
ZnO lightning arrester is one kind of protecting equipments preventing electric equipments in AC power system from high voltage and over-voltage operation.
