5KA Polymer Type Gapless Arresters

5KA Polymer Type Gapless Arresters

The Zinc Oxide arrester is the most advanced over-voltage protector in the world. This is due to a zinc oxide arrester as the core resistor disc.
Number
D002
Product Overview
Product parameters
This allows an improvement in the volt-ampere characteristics of the resistor disc and an increase in through-current capability in over-voltage situations, which is a drastic improvement when compared to conventional silicon carbide arresters.
 
Under normal operating voltage, the current  through  the arrester is only one micro-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.
These arresters comply with IEC60099-4 standard.
