For indoor primary power distribution at 40.5 kV and below, suitable for indoor installation
ZX2 gas-insulated metal-enclosed switchgear and controlgear is based on a comprehensive and innovative design concept. All primary live conductors are completely enclosed in high-voltage compartments filled with SF6 insulating gas. The circuit-breaker compartment and busbar compartment are mutually independent, and the compartment enclosures are made of stainless steel plates welded by advanced robotic welding, so the installed high-voltage live parts are completely unaffected by external environmental conditions. Personnel cannot access live parts, ensuring operational safety.
The main switch of ZX2 switchgear uses ABB's renowned VD4X vacuum circuit breaker, which offers stable performance and a long service life, meeting all requirements of single-busbar and double-busbar systems. It is suitable for demanding coastal and inland environmental conditions and is widely used in metro, power grid, petrochemical, public utility, and real estate sectors.
