Enhance grid reliability with our Polymer-ZnO Line Arresters, engineered to reduce lightning-induced outages in AC transmission systems (10kV-220kV). Installed parallel to insulators, these arresters clamp surge voltages, boosting line lightning resistance by 60%+. Choose suspension-type (tower-mounted) or stake-type installations for rugged terrains, mines, or coastal zones.Built with weather-resistant polymer housing, they comply with GB11032-2000 (IEC60099-4) and JB/T8952-2005 standards, ensuring 25+ years of maintenance-free service. Ideal for wind farms, industrial feeders, and substation lines.
