GW13-40.5/72.5/126(W)

GW13-40.5/72.5/126(W) series are professional outdoor high voltage neutral point disconnector switches, covering 40.5kV, 72.5kV and 126kV voltage levels. Complying with IEC and GB standards, they are mainly used for no-load switching and safe isolation of transformer neutral points in outdoor substations and power transmission projects.
Adopting a unique V-type double-column structure with 50° insulator intersection angle and 25° inclined bracket installation, the GW13 series features stable mechanical performance and compact layout. It has low contact resistance and reliable current carrying capacity, ensuring stable no-load switching operation.
Equipped with high-strength anti-fouling insulators with extended creepage distance, this W-type anti-pollution switch provides excellent insulation and anti-interference performance. It perfectly adapts to coastal, high-altitude, humid and heavily polluted harsh outdoor environments.
All metal components adopt hot-dip galvanized anti-corrosion treatment, with strong resistance to rust, oxidation and salt fog erosion. The optimized outdoor structural design withstands extreme weather changes, supporting long-term stable all-weather operation.
The switch supports both manual and electric operation modes, equipped with standard mechanical anti-misoperation interlock devices. It features flexible switching, high structural stability, simple installation and low daily maintenance costs.
As dedicated isolation equipment for transformer neutral point protection, GW13(W) series disconnectors deliver stable performance and outstanding environmental adaptability. We provide global customers with factory direct supply, complete certifications and professional after-sales service.
