Metal-oxide surge arrester introduction:

Polymer-housed metal oxide surge arrester is a scientific achievement combining the advantages of organic insulation materials and porcelain-housed arrester technologies. Therefore, polymer-housed metal oxide surge arrester not only has the advantages of porcelain-housed arrester, but also has other advantages, such as good electrical performance, strong dielectric strength, tracking resistance, high- and low-temperature resistance, aging resistance, sandstorm resistance, explosion-proof performance, sound chemical stability, and hydrophobicity. The housing is made of high-quality silicone rubber, and formed by one step with integral moulding and curing process, with high sealing performance and long service life. The polymer-housed arrester is designed and manufactured in strict accordance with GB 11032 and takes a leading position in the similar products in China. Featured by reliable protection performance and stable operation, the polymer-housed arrester is widely used in the major projects of State Grid Corporation of China (SGCC) and China Southern Power Grid Company Limited (CSG), including the following SGCC's projects: 1,000kV UHV Southeast Shanxi Substation of 1,000kV Southeast Shanxi - Nanyang - Jingmen UHVAC Pilot Demonstration Project, Extension Works of 1,000kV Nanyang Switching Station of 1,000kV Southeast Shanxi - Nanyang - Jingmen UHV AC Pilot Demonstration Project, South Hami Converter Station of ±800kV Hami- Zhengzhou UHVDC Electricity Transmission Project, 750kV East Lanzhou Station, 500kV Beijing Shunyi Substation, 750kV Gansu Baiyin Substation, 750kV Shaanxi Baoji Substation, 750kV Shazhou Substation, 750kV Qinghai Qaidam Substation and 500kV Baoji - Deyang DC Electricity Transmission Project, as well as DC De-icing Project of 500kV Hechi Substation of CSG EHV Power Transmission Company, DC De-icing Project of 500kV Anshun Substation of Guizhou Power Grid Company and 330kV Sanxing Substation in Xi'an High-tech Zone.


Description of type:

According to the JB/T 8459-2011,the type of MOA shows as below:

Product type: Y-porcelain-housed YH-polymer-housed  
Structure feature: W-without gap C-with series gaps B-with shunt gaps
Service condition: S-distribution Z-power station R-shunt capacitor
D-motor T-electrical railway X-overhead line
Additional feature: W-anti-pollution TH-for hot and humid area G-high altitude type
Average service conditions of metal-oxide surge arrester:

1.The metal-oxide surge arrester works both indoors and out;

2.The temperature of the metal-oxide surge arrester  is between  -40℃~+40℃;

3.The altitude of the metal-oxide surge arrester is not more than 2600 meters;

4.The AC power supply Frequency of the metal-oxide surge arrester is between 48Hz and  62HZ;

5.Power Frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage;

6. The intensity of the earthquake is 8 degrees or below;

7.The maximal wind speed of the metal-oxide surge arrester does not exceeding 35m/s. Special conditions of carriage are marked on the contract.

Advantages of metal-oxide surge arrester:
1.Metal-oxide surge arrester have characteristic of small partial discharge;
2.Metal-oxide surge arrester have low residual voltage;
3.Metal-oxide surge arrester have high dielectric insulation level;
4.The metal-oxide surge arrester can withstand high and low temperatures;
5.The metal-oxide surge arrester is Explosion-proof;
6.The metal-oxide surge arrester is corrosion resistant;
7.The metal-oxide surge arrester is anti-aging;
8. The metal-oxide surge arrester has a very short delivery time (Ex-work 1 week+).
