Product information

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”-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.
