The AC gapless metal oxide arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no freewheeling, large current capacity, low residual voltage, strong ability to suppress overvoltage, anti-pollution, anti-aging, not subject to altitude constraints, structure Simple, no gap, tight seal, long life and so on.
The arrester is in a high resistance state under normal system operating voltage, and only microampere current flows. It exhibits low resistance under the action of overvoltage and high current, thus limiting the residual voltage across the arrester.
