The AC gap free metal oxide surge arrester has excellent nonlinear volt ampere characteristics, good response characteristics, no continuous flow, large flow capacity, low residual voltage, strong suppression of overvoltage, dirt resistance, anti-aging, unrestrained by altitude, simple structure, no gap, tight sealing, long life and so on.

Under the normal system working voltage, the arrester presents a high resistance state, and only microampere current passes through. Under the action of overvoltage and large current, it presents low resistance, which limits the residual voltage at both ends of the arrester.
