Product Desciption

ZnO lightning arrester is one kind of most advanced over-voltage protector at present 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 charcateristics of resistance,increases the getting through ability of resistance,thereby it brings fundamental,change to features of arrester.

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 effective limits the damage to power transmission equipments due to over voltage.
