Description

Railway Polymer Gapless 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.
Metal oxide varistors are wrapped and fixed by PBT, after that a varistor rod shall be processed by vulcanizing machine into a completed surge arrester. This kind of uniq technics greatly improves SA electricl performance and shorten production time.
Advantage:
1/ Low partial discharge;
2/ Low residual voltage;
2/ High dielectric insulation level;
3/ Tolerance to high/low temperature;
4/ Explosion-proof;
5/ Anti-corrosion;
6/ Anti-aging;
7/ Shorter lead time (Ex-work 1 week+).
Standard Technical Data:
Below info. only for your reference, all data shall be specified and determined by technical specification and customer demand.
