● The zine oxide arrester is the most advanced over-voltage protector in the world;Due to make the risistor disc of core componet mainly adopt zine oxide arrester.Compared with the conventional silicon carbide arrester, this presciption of theproduct improves gr-eatly the volt-Ampere characterisics of the resistor disc andincreased through-current capability at over-voltage so as to dring a rad-icalchanges for the characteristics of the arresters.
● Under the circumstance of normal operating voltage, the current through thearrester is just on microampere degree, When suff-ered from over-voltage, thearrester's excellent nonlinear characteristics will make the current through thearrester incrase to several thousand amperse, while the arrester will be under thecirculating state and release over-voltage energy so as to protecting the powertransmission equipments against the demage caused by th over-voltage.
