[0002] The zinc oxide arrester is an arrester with good protection performance. Utilizing the good non-linear volt-ampere characteristic of zinc oxide, the current flowing through the arrester is extremely small under normal working voltage. When overvoltage acts, the resistance drops sharply, discharging the energy of the overvoltage to achieve the protection effect. The difference between this arrester and traditional arresters is that it has no discharge gap and uses the non-linear characteristic of zinc oxide to play the role of discharging current and breaking.
