10kV Transmission Polymer With Gap Surge Arrester
Product introduction:
Polymer-housed metal oxide surge arrester (MOA) combines advantages of organic insulation material and porcelain-housed MOA. It is of good electrical performance, high dielectric strength, resistance to high/low-temperature, to aging, as well as explosion-proof, excellent chemical stability, and hydrophobicity. Polymer housing is made of high-quality silicone rubber, formed by integral moulding and curing process which benefites sealing performance, service life and lead time.
Advantage:
1/ Low partial discharge;
2/ Low residual voltage;
3/ High dielectric insulation level;
4/ Tolerance to high/low temperature;
5/ Explosion-proof;
6/ Anti-corrosion;
7/ Anti-aging;
8/ Shorter lead time (Ex-work 1 week+).
