SF₆-free AirSeT innovation for medium voltage

An ingenious combination of pure air and vacuum switching technology, the new SF₆-free AirSeT MV switchgear makes buildings and electrical networks more sustainable and improves their efficiency. For more reliable and safer operations.

Sustainable growth with AirSeT MV innovation

Medium voltage switchgear is a critical component of electrical distribution. Urbanization and economic growth further drive infrastructure expansion. A significant part of the MV equipment deployed in the electrical network contains SF₆ gas, which has a high global warming potential (GWP). Our green SF₆-free AirSeT technology offers a way to reconcile growth implications and rapidly accelerating renewable generation and electrification with a sustainable approach to reducing your greenhouse gas inventory.

Combining pure air insulation, vacuum technology, and digital capabilities, our SF6-free AirSeT MV innovation offers unprecedented improvements for the operator, as well as public health and safety. On the one hand, it delivers solid and proven solutions for safer network management; on the other hand, it avoids human-made gases, thus eliminating the risks associated with leaks or toxic by-products.

With AirSeT, we enable businesses and electricity companies to transition to sustainable MV technology smoothly. Our offers maintain a compact physical footprint and can be deployed as an extension to existing switchgear. The ingenuity of the air  and vacuum solution allows us to offer the just-right solution for the application at hand. With EcoStruxure-ready digital technologies, the SF₆-free AirSeT MV equipment with Active connectivity helps improve safety, security, efficiency, modern asset management, and network optimization.

Medium voltage switchgear is a critical component of electrical distribution. Yet a significant part of the MV equipment deployed in the electrical network contains SF₆ gas, which has a high global warming potential (GWP). It is possible to remove SF₆ from the switch gear, but that often means replacing the SF₆ switch with a vacuum circuit breaker. It has three main drawbacks. It makes the equipment more complex and bigger. Fuse protection on a transformer is impossible. And operators are forced to change the way they work. However, thanks to innovation, we have managed to remove SF₆ from our MV switchgear.

Our new SF₆-free AirSeT switchgear technology powered by air and digital features aid businesses on their way to green buildings, green facilities, and a more sustainable grid. The SF₆-free AirSeT combines pure air insulation, shunt vacuum interruption technology, and digital capabilities. It offers unprecedented improvements with no change in the way you operate the switchgear. It can be deployed as an extension to existing switchgear. It has identical reliability and electrical performance. It stays compact in size, and we keep the fuse protection and the switch functions that make it the most cost-effective solution. With SF₆-free AirSeT, we enable businesses and electricity companies to transition to sustainable MV technology smoothly. Our blue sustainability offer maintains an offset carbon footprint. Now MV gets green technology with SF₆-free. Because we believe the best gas is pure air.
