⚡ 3~36kV 10kA Series Polymer-housed Metal-oxide Surge Arresters Main Parameters
Surge Arrester Main Parameters

1. Product Introduction

Metal-oxide arresters adopt zinc oxide resistors with excellent nonlinear voltage-current characteristics. These arresters offer superior steep wave response, high current-carrying capacity, significant energy absorption capability, low residual voltage, and an ample protection margin.

The protection margins for steep wave impulse residual voltage, lightning impulse residual voltage, and switching impulse residual voltage are nearly uniform, providing optimal insulation protection for electrical equipment. Metal-oxide arresters have gradually replaced traditional silicon carbide surge arresters as the dominant overvoltage protection solution.
