Metal oxide lightning arrester is a high-tech product from the 1990s internationally. It adopts oxygen zinc resistors with excellent nonlinear volt ampere characteristics, which greatly improves the protection characteristics of surge arresters under slope, lightning waves, and operating waves compared to traditional silicon carbide surge arresters. Especially zinc oxide resistors have good slope response characteristics, no delay in steep slope voltage, low residual voltage during operation, and no discharge dispersion. Thus, it overcomes the inherent disadvantages of high steep slope discharge voltage caused by steep slope discharge delay and large dispersion of operation wave discharge, which leads to high operation wave discharge voltage in silicon carbide lightning arresters. This greatly improves the protection margin under steep slope and operation wave, and in terms of insulation coordination, it can achieve similar protection margins for steep slope, lightning wave, and operation wave, providing excellent protection for power equipment and improving the reliability of protection. Zinc oxide lightning arrester has the ability to absorb lightning overvoltage, operational overvoltage, and power frequency transient overvoltage simultaneously. The composite jacket metal zinc oxide lightning arrester is a high-tech product of the international 1990s. It is molded with integral silicone rubber, with good sealing performance, excellent explosion-proof performance, pollution resistance and no cleaning, and can reduce the occurrence of wet flashes in foggy days. It is resistant to electrical corrosion and aging, small in size and light in weight, and collision resistant, which is convenient for installation and maintenance. It is an upgraded product of porcelain bushing lightning arrester.
