Deskripsi
Porcelain Gapless DC Surge Arrester
Series : Y5WR
Certification : IEC 60099-4/ GB 11032
MFR : SHENDIAN ELECTRIC
Introduction:
Porcelain surge arrester is of high mechanical strength, longer creepage distance, excellent electrical insulation performance, strong dielectric strength, tracking resistance, high- and low-temperature resistance and sandstorm resistance. The multi-sealing structure of the housing provides high sealing performance and long service life.
Advantage:
1/ High mechanical strength;
2/ Longer creepage distance;
3/ High dielectric insulation level;
4/ Tolerance to high/low temperature;
5/ Anti-corrosion and anti-aging;
