  • China Best Price High Voltage Equipment Solid and Durable15-33KVA Zinc oxide arrester

    The metal zinc oxide arrester is a high-tech product in the 1990s in the world. It uses zinc oxide resistors with excellent nonlinear volt- -ampere characteristics, so the protection characteristics of the arrester under steep slopes, lightning waves, and operating waves are greatly improved compared with traditional silicon carbide arresters. In particular, zinc oxide resistors have good steep slope response characteristics, no delay to steep slope voltage, low operating residual voltage, and no discharge electricity dispersion. Therefore, it overcomes the inherent shortcomings of silicon carbide arresters, such as high discharge voltage on steep slopes caused by the delay of steep slope discharge, and high operating wave discharge voltage caused by large operating wave discharge dispersion, so that the protection margin under steep slopes and operating waves is greatly improved. , and in terms of insulation coordination, the protection margins of steep slopes, lightning waves, and operating waves can be made close to the same, so as to provide the best protection for power equipment, thereby improving the reliability of protection. Zinc oxide arresters also have the ability to absorb lightning overvoltage, operating overvoltage and power frequency transient overvoltage.?The composite jacket metal zinc oxide arrester is a high-tech product in the 1990s in the world. It adopts integral silicone rubber molding, which has good sealing performance, excellent explosion-proof performance, no cleaning for contamination, and can reduce the occurrence of wet flash in foggy weather. It Is an updated product of porcelain sleeve mines.

    Feature

    1.Lightning arrester element can be assembled or disassembled at any time with electricity, particularly surtabte for the places where shouki no< have biackout.
    2.With disconnector, lightning arresler element can tum down automatically and exit working if there comes the fautt, ensuring the line's nonnal traffic.
    3.There are clear marks for element turned down for the fault easy Io find for timely maintenance or replacement.
    4.Lightning arrester adopts composite housing and the dropout structure takes composite pillar with good hydrophobic performance and pollution resistance.
