JW2-126/252(W)
Built with optimized structure and premium conductive parts, the JW2(W) series has low contact resistance and stable grounding performance, ensuring fast and reliable circuit grounding to protect equipment and operators during maintenance.
Equipped with anti-fouling insulators with extended creepage distance, this W-type anti-pollution earthing switch provides excellent insulation and anti-interference performance, adapting to coastal, high-altitude, humid and heavily polluted outdoor scenarios.
All metal components adopt hot-dip galvanized treatment for strong rust, oxidation and salt fog resistance. The outdoor-rated structure withstands harsh weather for stable all-weather operation.
With reliable transmission and interlock structure, the switch supports manual and electric operation. It features flexible switching, easy installation, high stability and low maintenance.
Serving as key safety grounding equipment for 126kV-252kV power grids, JW2(W) series earthing switches deliver stable performance and strong environmental adaptability. We offer factory direct supply, complete certifications and professional after-sales service worldwide.
