HV Contact Parts for MV, HV, and EHV Circuit Breakers maintain quite regular shape under extreme arcing conditions and have only uniform roughening effect without cracks and burn-off droplets. The Tungsten skeleton is protected by impregnated Copper as it provides evaporative cooling effect in extreme arcing conditions, thereby protecting and limiting the temperature rise of the skeleton and preventing disintegration.
