Detailed Product Description

Zno lighting 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 makde 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 ua 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,there fore it effective limits the damage to power transmission equipments due to over voltage.
