We combine excellent technologies with innovative thinking. This is our vision for creating the sustainable power distribution of tomorrow.

The 8DAB 12 blue GIS complements the traditional 8DA/B switchgear portfolio for medium-voltage. It was developed using our experience with more than 100,000 panels and offers the same performance customers all over the world are familiar with – but without F-gas as an insulating gas.

• Up to 12 kV, 40 kA, and 2,750 A
• Circuit-breaker switchgear 

The 8DJH 12 – blue GIS is an extension of the globally successful 8DJH product family up to 12 kV. Clean Air and the proven Siemens vacuum technology offer all benefits of a gas-insulated switchgear and allow to create sustainable power distribution at the same time.

• Up to 12 kV, 21 kA and 630 A
• Ring-main-unit 

The new NXPLUS C 24 – blue GIS with Clean Air is a versatile and compact single-busbar switchgear for the primary distribution level of up to 24 kV, 25 kA and 1,250 A. It uses proven Siemens vacuum technology and offers all the advantages of a gas-insulated switchgear without F-gas.

• Up to 24 kV, 25 kA and 1,250 A
• Circuit-breaker switchgear

The switchgear type 8DJH has been an integral part of the Siemens secondary medium-voltage portfolio for more than a decade. Now it's time to advance the F-gas-free future with our new 8DJH 24 – blue GIS for up to 24 kV.

• Up to 24 kV, 21 kA and 630 A
• Ring main unit
