Siemens Smart Infrastructure has cemented its position as a technology leader by expanding its sustainable blue GIS portfolio with the 8DAB 40. This switchgear for primary distribution networks up to 40,5 kV uses “Clean Air” as insulating medium with GWP <1, making it climate friendly and completely free of fluorinated gases. The 8DAB 40 is to be showcased at the upcoming Hannover Messe, taking place from April 17th to 21st. Free tickets are available to be part of the Siemens experience. Siemens Xcelerator is an open digital business platform that enables customers to accelerate their digital transformation easier, faster, and at scale. Developed based on industry-leading vacuum-interrupter technology, this highly innovative switchgear is Siemens’ first step to address 40,5 kV market requirements, enabling environmentally-friendly grid expansion without fluorinated gases. By combining Clean Air, consisting of natural-origin gases, for insulation with proven vacuum-interrupter technology, blue GIS is supporting customers’ endeavor to reduce their carbon footprint and paves the way for a more sustainable future.

“As utilities and industries strive to meet ambitious targets to decarbonize and digitalize grids, they are looking for sustainable, intelligent and future proof products also for higher voltage ratings,” says Stephan May, CEO of Electrification and Automation at Siemens Smart Infrastructure.

“Our sustainable and innovative 8DAB 40 blue GIS is the answer to an eco-friendly energy transition. Using Clean Air and vacuum-interrupter technology, all the benefits of a conventional 8DA/B switchgear up to 40,5 kV level are kept. The 8DAB 40 offers the same performance while keeping identical panel dimensions and utilizing technology that has proven to be successful and reliable for more than 40 years. Designed on the pillars of the Siemens DEGREE program, it has a reduced CO2 footprint throughout its lifecycle, making it a sustainable switchgear.”

8DAB 40 switchgear with its modular and compact design is suitable for various critical infrastructure applications, like data centers, semiconductor manufacturing industries, and green hydrogen production. It further offers excellent reliability and safety, thanks to its sealed-for-life and single-pole enclosed design, making the 8DAB 40 an ideal choice for utilities and other critical industries looking to reach their sustainability targets.

Offering numerous benefits thanks to its integrated digital technologies, the 8DAB 40 was developed with the highest focus on cyber security, and provides real-time monitoring, remote control, and diagnostics capabilities. Customers reap the rewards of improved operational efficiency, reliability, and safety. Thanks to real time condition monitoring, 8DAB 40 allows predictive maintenance to reduce downtime and maintenance costs.
