HY5WS-10kV lightning arrester

HY5WS-10kV lightning arrester is an efficient lightning protection device designed specifically for 10kV distribution systems. It uses Zinc Oxide valve plates (ZnO) and high-strength silicone rubber composite jackets, which can quickly suppress lightning and operating overvoltage, and reduce line tripping rate by more than 60%. Compliant with GB 11032-2000 (equivalent to IEC 60099-4) standard, fully sealed maintenance free structure, able to withstand extreme temperatures from -40 ° C to+70 ° C, resistant to salt spray and UV aging, with a lifespan of over 25 years. Suitable for rural power grids, industrial plants, and photovoltaic power station distribution lines, especially suitable for coastal or mountainous environments with high humidity and frequent thunderstorms.
