Main principle:
· Zno lighting arrester is one kind most world advanced over-voltage protector at present,due to its core components of resistanceapply-
ing Zno adn other metal oxide to make of,comparing with traditional carborundum arrester,it improves greatly V-Acharacteristics of resistance,increases the getting trough ability of resistance,thereby it brings fundamental change to features of arrester.
· Under normal working voltage, the current passing arrseter onlyu A class,when bearing over voltage,the escellentnon-linear V-Afeatures of arrester would make effect,the current passing through the arrester increase high to thoudands of Ampere instant,the arrester is under getting through state,to release over-voltage energy,therefore it effectve limits the admage to power transmission equiqments due to over voltage.
·Applicafion and feafures:
· Zno lighting arrester is one kind protecting equipment preventing electric equipments in AC power system from high voctage and over-voltage operation.
