product introduction
metal oxide arrester WGM0A is international in the 1990s high-tech products. The use of nonlinear V-I characteristics very excellent zinc oxide varistor M0R. Therefore arrester wave steepness and lightning wave, wave operation of protective properties phase than traditional silicon carbide arrester has a greatly improved. In particular, zinc oxide film has good characteristics of steep wave response, and has no delay in the steep slope, the operation is disabled, no discharge, etc.. So as to overcome the high voltage discharge voltage caused by steep steep discharge caused by steep steep discharge, the operation wave discharge voltage is high, and the protection margin is greatly improved, and the protection margin of the insulation coordination is close to the insulation coordination. Zinc oxide surge arrester at the same time has the ability to absorb lightning over-voltage, operating over-voltage and power frequency transient over-voltage.
composite coat zinc oxide arresters with overall silicon rubber molding, good sealing performance, excellent explosion-proof performance, resistance of filth, free cleaning, and can reduce the occurrence of fog wet flashover, high electrical erosion, anti-aging, small volume, light weight, resistance to collision, installation and maintenance.
