HY5WZ-3~6kV arrester is specially designed for 3kV-6kV low-voltage distribution system. It uses high-performance zinc oxide valve (ZnO) and anti-aging silicone rubber composite jacket to effectively restrain lightning and switching overvoltage and reduce line tripping rate by 55%+. Compliant with GB 11032-2000 (equivalent to IEC 60099-4) standard, fully sealed maintenance free structure, capable of withstanding environmental temperatures ranging from -30 ° C to+60 ° C, resistant to moisture and chemical corrosion, with a lifespan of over 20 years. Suitable for low-voltage distribution cabinets in factories, power supply systems in commercial buildings, and small rural substations, especially suitable for scenarios with limited space and poor maintenance conditions.
