Product description and usage:
1.Overview
Metal oxide arrester is a high-tech product in the 1990s. It adopts oxygen zinc resistor with excellent nonlinear V-A characteristics. Therefore, the protection characteristics of lightning arrester under slope, lightning wave and operation wave are greatly improved compared with the traditional silicon carbide lightning arrester. In particular, zinc oxide resistor has good slope response characteristics, no delay to steep slope voltage, low operation residual voltage and no discharge dispersion. Thus, the silicon carbide arrester overcomes the inherent disadvantages of high steep slope discharge voltage caused by steep slope discharge delay and high operation wave discharge voltage caused by large dispersion of operation wave discharge, which greatly improves the protection margin under steep slope and operation wave, and can achieve nearly the same protection margin of steep slope, lightning wave and operation wave in terms of insulation coordination, So as to provide the best protection for power equipment, and then improve the reliability of protection. Zinc oxide arrester has the ability to absorb lightning overvoltage, operating overvoltage and power frequency transient overvoltage at the same time. Composite coat metal zinc oxide arrester is a high-tech product in the 1990s. Molded by integral silicone rubber, it has good sealing performance, excellent explosion-proof performance, no dirt and no washing. It can reduce wet flash, corrosion resistance, ageing resistance, small size, light weight, collision resistance, easy installation and maintenance. It is an updated product of porcelain bushing arrester.
