Surge Arrester with Series Gap

Features an integrated series spark gap that isolates the arrester core from normal system voltage. Eliminates continuous degradation from leakage currents and offers high pollution resistance for severe atmospheric conditions.

The resistor chip adopts the aluminum spraying technology without free edges, which makes its current-carrying capacity larger and can be increased by 15-20% in comparison.
The side insulation of the resistor chip adopts the glass glaze process. Compared with the insulating paint, its heat-resistant temperature is 100℃-200℃
Assembled in a large-scale environment that has passed MA inspection, the temperature and humidity inside the arrester are effectively controlled, thus ensuring the long-term and reliable operation of the arrester.
