Porcelain 110kV surge arrester

110kV Railway Porcelain Gapless Surge Arrester

 

Product introduction:

Normally there are 2 kinds of DC SA for railway system:

1/ 750V, Ur=1.0kV, 8/20μs residual voltage at 20kA: 2.4kV;

2/ 1500V, Ur=2.0kV, 8/20μs residual voltage at 20kA: 4.8kV.

 

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.
 
Shendian takes lead of SA in China, its product is widely used in State Grid Corporation of China (SGCC) and China Southern Power Grid (CSG), among them including many extraordinary projects:
(1) 1,000kV UHV Southeast Shanxi Substation of 1,000kV Southeast Shanxi - Nanyang - Jingmen UHVAC Pilot Demonstration Project,
(2) Extension Works of 1,000kV Nanyang Switching Station of 1,000kV Southeast Shanxi - Nanyang - Jingmen UHV AC Pilot Demonstration Project, (3) South Hami Converter Station of ±800kV Hami- Zhengzhou UHVDC Electricity Transmission Project,
(4) 750kV Qinghai Qaidam Substation and 500kV Baoji - Deyang DC Electricity Transmission Project, as well as
(5) DC Project of 500kV Hechi Substation of CSG,
(6) DC Project of 500kV Anshun Substation of Guizhou Power Grid Company and 330kV Sanxing Substation in Xi'an High-tech Zone.
 
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;
