Product details
Product overview:
The metal zinc oxide trap is a high-tech product from the 1990s internationally. it uses zinc oxideresistors with excellent nonlinear volt ampere characteristics, which greatly improves the protectioncharacteristics of lightning arresters under steep slopes, lightning waves, and operating wavescompared to traditional silicon carbide lightning arresters. Especially zinc oxide resistors have goodsteep slope response characteristics, no delay in steep slope voltage, low residual voltage duringoperation, and no discharge dispersion. Thus, it overcomes the inherent disadvantages of high slopedischarge voltage caused by steep slope discharge delay and high operation wave discharge voltagedue to large dispersion of operation wave discharge in silicon carbide lightning arresters, greatlyimproving the protection margin under steep slopes and operation waves. Moreover, in terms ofinsulation coordination, it can achieve similar protection margins for steep slopes, lightning waves.and operation waves, providing optimal protection for power equipment and improving the reliabilityof protection. Zinc oxide lightning arrester has the ability to absorb lightning overvoltage, operationalovervoltage, and power frequency transient overvoltage simultaneously.The composite jacket metal zinc oxide lightning arrester is a high-tech product from the 1990sinternationally. lt is molded with integral silicone rubber, which has good sealing performance andexcellent explosion-proof performance. Pollution is free from cleaning, and can reduce the occurrenceof wet flashes in foggy days. lt is resistant to electrical corrosion and aging, small in size and light inweight, and colision resistant, which is convenient for installation and maintenance. lt is an upgradedproduct of porcelain bushing lightning arrester.
