Under the normal system operating voltage, the surge arrester presents a high resistance state, and only microampere current passes through. Under the action of overvoltage and high current, it presents low resistance, which limits the residual voltage at both ends of the arrester. Optional arresters are more suitable for complex environmental choices , The voltage range of Zhongyi Surge Arrester Series can be selected between 3-36 kv, and ZhongYi products have the qualification certification of KEMA.
