Overview
This arrester uses zinc oxide resistor with excellent nonlinear volt ampere characteristics. Therefore, compared with traditional silicon carbide arrester, the protection characteristics of the arrester under steep slope, lightning wave and working wave are greatly improved. In particular, zinc oxide resistors have the advantages of good steep slope response characteristics, no delay for steep slope voltage, low operation residual voltage and no discharge electric dispersion. It is molded with integral silicone rubber, with good sealing performance and explosion-proof performance. It can be cleaned without cleaning, so as to reduce the occurrence of wet flash in foggy days. Leo's new rain product. In terms of insulation coordination, it can make the protection margins of steep slope, lightning wave and working wave close to the same, so as to provide the best protection for power equipment and improve the reliability of protection. Zinc oxide arrester also has the ability to absorb lightning overvoltage, switching overvoltage and power frequency transient overvoltage. Features
