high-voltagegas-insulatedpower distribution

Substations with gas-insulated switchgear Siemens high-voltage substations with gas-insulated switchgear (GIS) are ideally suited to meet some of today’s most important requirements: bringing power on high-voltage levels right into the centers of urban areas. With almost 50 years of GIS manufacturing experience, the largest installed base of GIS, and a long track record of superior turnkey supply, Siemens is able to provide true one-stop GIS solutions that even comprise operational training. More than 34,500 Siemens GIS bays are currently in operation in GIS substations all over the world – even in most challenging environments. The comprehensive range of GIS for rated voltages from 72.5 kV to 550 kV provides ideal solutions for indoor and outdoor switching applications up to the highest performance rates that require: •a small footprint •outstanding reliability •very low noise and electromagnetic emissions
