8DAB 12 - blue GIS
Gas-insulated switchgear (GIS) type 8DA/B has been an integral part of the medium-voltage portfolio at Siemens. More than 100,000 panels of this switchgear type have already been installed worldwide. The 8DA/B portfolio has now been extended by 8DAB 12 – a switchgear using Clean Air, an insulating gas exclusively consisting of natural elements of the ambient air. The new 8DAB 12 belongs to the “blue GIS” portfolio of Siemens AG. Every GIS of this portfolio is equipped with Clean Air and the proven Siemens vacuum technology, offering all advantages of a gas-insulated switchgear at the same time.Features of blue GIS
