Gas-Insulated Switchgear (GIS)
Advanced gas-insulated switchgear with stainless steel sealed enclosures and maintenance-free operation for demanding environments.
GSN3-12 Eco-Friendly Gas-Insulated Switchgear (12kV)
The GSN3-12 is a new-generation eco-friendly AC metal-enclosed gas-insulated switchgear (C-GIS) for 12kV applications. Uses nitrogen instead of SF6 for environmentally responsible insulation, with stainless steel welded construction and vacuum switching technology.
GSN1-40.5L Gas-Insulated Switchgear (40.5kV)
The GSN1-40.5L is a 40.5kV AC metal-enclosed gas-insulated switchgear (C-GIS) with dual gas chamber design. Features stainless steel laser-welded enclosure with annual leakage rate below 0.05%, capable of operating at zero gauge pressure.
