LifeSF6free for greener energy
Objectives: What is behind the SF6-free MV project?
SF6 is the most potent greenhouse gas in terms of GWP (Global Warming Potential). The gas was chosen to be used in gas MV electrical equipment in the 60s for its tremendous qualities, but each kilogram of SF6 constitutes the equivalent of 24,300 ton of CO₂ representing a well identified environmental impact. So far, each step towards a low carbon policy was blocked by lack of alternative MV technologies. SF6 can be replaced by an effective, robust, and affordable solution in MV applications. Intensive R&D work has now produced mature solutions. After several years of extensive research and multiple alternatives assessments, Schneider Electric proposes the combination of pure air and vacuum technology in an innovative switching device.
The pilot project, with prototypes running on customers sites in real conditions, demonstrated to all stakeholders and target audiences that these alternatives are safe and reliable in various MV applications. The total budget dedicated to this initiative was 5.9 M€ with EU financial contribution of 3.2 M€ (55%).
Schneider Electric is working with multiple customers across in the EU zone to deploy SF6-free medium-voltage switchgear pilot installations. These range from SF6-free secondary AIS and GIS to primary distribution equipment.
The initial feedback and results from customers indicate high level of satisfaction with the SF6-free MV solution. The transparency of the green design coupled with the uncompromised performance and reliability answer their need to curb their environmental footprint while boosting operational uptime.
SM AirSeT is a green range of secondary distribution modular air-insulated switchgear up to 24kV for the commercial and industrial building sector and utilities.
