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.


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.
