Upgrade your grid reliability with the Polymer-ZnO Line Arrester, a maintenance-free surge protection solution for AC transmission systems (10kV-220kV). Installed parallel to insulators, this arrester clamps lightning overvoltages, reducing trip rates by 60%+ and enhancing line lightning resistance. Choose suspension-type (tower-mounted) or stake-type installation for rugged terrains like mines, coasts, or mountainous regions.
