The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through-current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

FAQ for Surge Arresters
Q: How about the performance of your surge arresters?
A: We use reliable material from our supplier and each batch material have qulified certificate. And the assemblied product also 100% tested before package.
Q: Can we customize the surge arresters according to our drawing/design?
A: Yes, we accept customized order, but the quantity needs to reach at 1000pcs if the mold fee are beared by you. For mold fee beared by us, the quantity need to reach to a large one.
Q: What kind of certificate of the surge arrester you have?
A: We have KEMA etc.
Q: What is the warranty for the surge arrester?
A: For the all surge arrester, we offer 2 years warranty for free.
