Metal oxidation arrester is a high - tech product in the 90 s. It adopts oxygen zinc resistor with very excellent nonlinear volt-amp characteristic, so the protection characteristics of arrester under slope, lightning wave and operation wave are greatly improved compared with the traditional silicon carbide arrester. In particular, ZNO resistor has good slope response characteristics, no delay to steep slope voltage, low operating residue, no discharge dispersion, etc. Thus suits the silicon carbide arrester discharge because of the steep slope of the delay caused by the inherent high steep slope of the discharge voltage, discharge wave dispersion caused by big operation wave discharge voltage higher shortcomings, steep slope, operating under the wave of the protection of the margin is greatly improved, and in terms of insulation coordination, can achieve a steep slope, thunder electric wave, wave protection margin nearly consistent operation, thus for power equipment to provide the best protection, thus to improve the reliability of protection. ZNO arrester has the ability to absorb lightning overvoltage, operating overvoltage and power frequency transient overvoltage simultaneously.

Composite jacket metal zinc oxide arrester is a high-tech product of the 1990s.Adopt integral silicone rubber molding, good sealing performance, excellent explosion-proof performance, anti-pollution and anti-cleaning, and can reduce fog wet flash, corrosion resistance and aging resistance, small volume, light weight, collision resistance, easy to install and maintain. It is the replacement of porcelain arresters.
