Zinc oxide arrester has good protection performance.The current flowing through the arrester at normal working voltage is very small (microampere or milliampere) due to the good nonlinear voltage-ampere characteristic of zinc oxide.When the overvoltage action, the resistance dropped sharply, let off the voltage energy, to achieve the effect of protection.The difference between this kind of arrester and traditional arrester is that it has no discharge gap and USES the non-linear characteristic of zinc oxide to discharge and break.
