Medium-voltage blue GIS

The Siemens blue GIS portfolio operates with Clean Air and proven, reliable vacuum switching technology, offering all advantages of a high-tech gas-insulated switchgear at the same time.

Joint statement of T&D equipment manufacturers for a sustainable energy distribution for the future

The clean transport of low-carbon electricity is an essential element of national decarbonization plans, which will underpin the sustainable economies of the future.
In conjunction with the generation of electricity from renewable energy sources, it is vital to do the same for transmission and distribution power grids upon which the energy system relies on.
For a sustainable, climate-neutral power grid we already offer the blue GIS portfolio with Clean Air as environmental harmless, non toxic and F-gas-free power distribution solution and help switching to a sustainable future. 

We have committed to this goal, find the official statement here.




Siemens blue GIS

Siemens blue GIS meets the high expectations of customers for high-tech gas-insulated switchgear, such as switchgear availability, maintenance-free design, personal safety, compactness, and environmental independence. Its gas insulation by Clean Air consists of the natural elements of the ambient air and is therefore free of fluorinated substances (F-gases), delivering a global warming potential < 1. Clean Air is hazard-free, highly stable, non-toxic, non flammable, and suitable for every application temperature.
