GIS Surge Arrester
Product introduction:
This kind of surge arrester is used in SF6 gas-insulated swtichgear.
Advantage:
1/ Low partial discharge and Low residual voltage;
2/ High mechnical strength, good sealing.
3/ High dielectric insulation level;
4/ Tolerance to high/low temperature;
5/ Explosion-proof;
7/ Top lead-out, side lead-out. bottom lead-out. etc;
8/ Optimized structure, easy installation and reliable quality.
