PRODUCT DESCRIPTION
ZnO lightning arrester is one kind most world 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 characteristics of resistance, increases the getting trough ability of resistance, there by it brings fundamental change to features of arrester.Under normal working voltage, the current passing arrester only A class, when bearing over voltage, the escellent 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.
