The zine oxide arrester is the mostadvanced over-voltage protector in the world,Due to make the risistordisc of core componetmainy adopt zine oxide arrester.Compared with the conventional silicon carbide arresterthis presciption of theproduct improvesgr-eatly the volt-Ampere characterisics of the resistor disc andincreased through-currentcapability at over-voltage so as to dring arad-icalchangesforthe characteristics of the arresters.
