Metal-oxide surge arrester-Aapless MOA for Distribution

 

Metal-oxide surge arrester introduction:

Metal-oxide surge arrester is one of the most advanced protectors limiting overvoltage, and is the basis of the insulation coordination equipment in power industry.Metal-oxide surge arrester has many advantages such as quick action, flat Vol-ampere characteristics, low residual voltage, high discharge current capacity, stable electrical performance,long lifecycle,simple structure and etc.Metal-oxide surge arrester is widely used in power generation, transformation and distribution system to prevent the insulation of the power equipments from being damaged by the over-voltage.

Polymer-housed metal-oxide surge arrester is the scientific achievement that combines the advantages of organic insulation material and traditional porcelain-clad MOA technique.Metal-oxide surge arrester has excellent insulation performance,high dialectical strength,anti-leaking,anti-electric corrosion,heat-resisting,cold-resisting,anti-aging,explosion-proof,and good chemical stability,hydrophobic property,and nice sealing.Metal-oxide surge arrester is designed and manufactured strictly following the standard of GB 11032 and achieves advantage against the competitive international products.

 

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
 
Normal service conditions of metal-oxide surge arrester:

1.For indoors and outdoors;

2.Ambient air temperature within the range of-40℃~+40℃;

3.Altitude not exceeding 2600m;

4.Frequency for A.C.power supply not less than 48Hz and not exceeding 62HZ;

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

6.Earthquake intensity:8 degree and below;

10.Maximal wind velocity not exceeding 35m/s. Please indicate in the contract,at exceptionally movement condition.

 
Advantage of metal-oxide surge arrester:
1.Metal-oxide surge arrester have low partial discharge;
2.Metal-oxide surge arrester have low residual voltage;
3.Metal-oxide surge arrester have 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+).
