The HY5WS-17/50C Line Overvoltage Arrester is a high-performance surge protection device designed for 10kV-35kV distribution lines, effectively clamping lightning strikes and switching surges. Featuring a silicone rubber polymer housing and zinc oxide (ZnO) varistors, it withstands harsh environments like coastal salt spray, industrial pollution, and extreme temperatures (-40°C to +70°C). Compliant with GB 11032-2000 (IEC 60099-4) and JB/T 10497-2005, this arrester reduces lightning-induced outages by 65%+ with a maintenance-free lifespan of 25+ years. Ideal for rural grids, wind farms, and mining substations.
