Surge Protective device adopts a splendiferous & non -linear characteristic sensitvity resistance, under normal condition, surge arrester is under skyscraping resisitance condition, without any leaking, assuring power system under normal power supply. When the power system have above over voltage, the surge arrester will conduct within a few minutes limit the value of over voltage under normal and safe range. Meanwhile release the over-voltage, then the arrester will become high-resistance condition quickly, such will not interfere thenormal power supplying of the power system
