gapless metal oxide arrester has excellent nonlinear volt-ampere characteristics, good response characteristics, no continuous current, large through-current capacity, residual low pressure, strong inhibition of overvoltage, pollution resistance, anti-aging, not restricted by altitude, simple structure, no gap, tight sealing, long life and so on.
The arrester presents a high resistance state under normal system operating voltage, and only microampere-level current passes through. Under the action of overvoltage and high current, it presents low resistance, thus limiting the residual voltage at both ends of the arrester
