Product Description

Lightning arrester is the most advanced over-voltage protector in the world. Its core element, metal oxide varistor (MOV), is made under Japanese technology license. Under the circumstance of normal operating voltage, the current through the lightning arrester is just on microampere degree. When suffered from over-voltage, the lightning arrester’s excellent non-linear characteristic will make the current through the lightning arrester increase to several thousand amperes. And the lightning arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the damage caused by the over-voltage.
