3kV polymer lightning arrester
The Zinc Oxide arrester is the most advanced over-voltage protector inthe world.This is due to the incorporation of a zinc oxide arrester as the core resistor disc.
This allows an improvement in the volt-ampere characteristics of the resistor disc and an increase in through-current capability in over-voltage sistuations, which is a drastic Improvement when compared to conventional silicon carbide arresters.Under normal operating voltage,the current through the arrester is only one mic-ampere degree. When the arrester experiences an over-voltage situation, the excellent non linear characteristics will increase the current through the arrester several thousand times. The arrester is in the conducting state and will release the over-voltage energy to earth and thereby protecting power transmission equipment against the effects of over-voltage.
