| 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 make of, comparing with traditional carborundum arrester, it improves greatly V-A characteristics of Resistance, increases the getting trough ability of resistance, thereby it brings fundamental 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 t he damage to power transmission equipments due to over Voltage. |
