10kv metal zinc oxide lighting surge arresterThe metal oxidation arrester adopts an oxygen-zinc resistor with excellent nonlinear volt-ampere characteristics. Therefore, the protection characteristics of the lightning arrester, the lightning wave and the operating wave are greatly improved compared with the conventional silicon carbide arrester. In particular, the zinc oxide resistor has good slope response characteristics, no delay for steep slope voltage, low operating residual pressure, and no discharge dispersibility. Therefore, the disadvantages of the steep slope discharge voltage caused by the steep slope discharge delay inherent in the silicon carbide arrester, the large dispersion of the operating wave discharge and the high operating wave discharge voltage are overcome, so that the protection margin of the slope and the operation wave is greatly improved. Moreover, in terms of insulation coordination, it is possible to achieve a steep slope, lightning waves, and the protection margin of the operating wave is nearly uniform, thereby providing better protection for the power equipment, thereby improving the reliability of the protection. The zinc oxide surge arrester has the ability to absorb lightning overvoltage, operate overvoltage and power frequency transient overvoltage.
The composite jacket metal zinc oxide arrester is a high-tech product of the international 90s. It adopts integral silicone rubber molding, good sealing performance, excellent explosion-proof performance, pollution-free cleaning, and can reduce the occurrence of foggy wet flash, resistance to electric corrosion and aging, small size, light weight, collision resistance, easy to install and maintain. It is a new generation of porcelain sleeve arresters.
