Home / GIS and HV switchgear
Compartments that cannot be opened until the gas is in the cart.
GIS bays and SF6 breakers are the reason this equipment exists. The gas is the insulation. Removing it carelessly is both an emission and a delay.
GNR recovery systems are specified around that compartment: hose reach, storage volume, residual pressure the owner will accept, and an oil-less path so the same gas can return.
CEPRI, ABB (Beijing), Mitsubishi Group and ALSTOM (Suzhou) are the names already attached to GNR’s public brief. They are listed here as published trust marks, not as fabricated case studies.
