金属氧化避雷器是国际上90年代的高科技产品。采用了非线性伏-安特性十分优异的氧气锌电阻片，故而避雷器的陡坡，雷电波，操作波下的保护特性均比传统的碳化硅避雷器有了极大的改善。特别是氧化锌电阻片具有良好的徒坡响应特性，对陡坡电压无迟延，操作残压低，没有放电分散性等优点。
Metal oxide arrester is a high-tech product in the 1990s. Zinc oxide resistors with excellent non-linear volt-ampere characteristics are used, so the protection characteristics of the lightning arrester under steep guangdaon.37ix.com.cnchoushag.37ix.com.cn jiaoni.07858.netbuxiugang.37ix.com.cntuoliutayq.37ix.com.cn zujuji.37ix.com.cnslope, lightning wave and operation wave are greatly improved compared with the traditional silicon carbide arrester. In particular, zinc oxide resistors have good slope response characteristics, no delay to steep slope voltage, low residual voltage and no discharge dispersion.
