Zinc oxide lightning arrester is a lightning arrester with good protective performance. By utilizing the excellent nonlinear volt ampere characteristics of zinc oxide, the current flowing through the lightning arrester at normal operating voltage is minimized (microampere or milliampere level); When overvoltage is applied, the resistance drops sharply, releasing the energy of the voltage and achieving the protective effect. The difference between this type of lightning arrester and traditional lightning arresters is that it does not have a discharge gap and utilizes the nonlinear characteristics of zinc oxide to perform leakage and disconnection.
