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.
