GW8-40.5/72.5/126(W)

GW8-40.5/72.5/126(W) series are high-performance outdoor high voltage disconnector switches for 40.5kV to 126kV power systems. Complying with IEC and GB standards, they are widely used in outdoor substations and power transmission projects for circuit isolation and no-load switching.
Featuring a compact vertical rotary structure and premium conductive parts, the GW8(W) series has low contact resistance and stable current carrying capacity, ensuring efficient power transmission without overheating during long-term operation.
Equipped with anti-fouling insulators with extended creepage distance, this W-type anti-pollution switch delivers excellent insulation and anti-interference performance, suitable for coastal, high-altitude, humid and heavily polluted outdoor environments.
All metal components are hot-dip galvanized for superior rust, oxidation and salt fog resistance. The optimized outdoor structure withstands extreme weather, enabling stable all-weather long-term operation.
Built with mechanical anti-misoperation interlocks, the switch supports manual and electric operation. It features flexible switching, high stability, easy installation and low maintenance.
Ideal for medium and high voltage power grid projects, GW8(W) series disconnectors offer stable performance and strong environmental adaptability. We provide global customers with factory direct supply, complete certifications and professional after-sales service.
