With the acceleration of electrification in different industries, there’s an increased need for a reliable, sustainable and digital energy infrastructure. Regulatory parameters such as Regulation (EU) 2024/573 regarding fluorinated greenhouse gases, encourage electricity distribution network operators, the industry, the real-estate market, data centers and infrastructure systems to switch to SF-free technologies. “With one of its latest developments – GM AirSeT, the global group Schneider Electric has expanded its portfolio of SF₆-free solutions, establishing itself as a market leader in secondary medium voltage switchgear and entering the segment of primary GIS applications. The technology provides a sustainable and future-oriented alternative for energy network operators, data centers and electricity-intensive sectors,” Schneider Electric Bulgaria commented to Engineer.bg

“The AirSeT range is evolving rapidly. With the new GM AirSeT line, we can support large energy users and grid operators in their efforts to decarbonize and adapt to upcoming European regulatory requirements, while moving to higher-power applications,” said Melton Chang, Executive Vice President, Power Systems, Schneider Electric.

This primary gas-insulated switchgear is a compact digital solution without SF, aimed towards the most demanding applications. For insulation, it uses clean air instead of gas mixtures or alternative fluorinated greenhouse gases. Eliminating the need for recycling and specialized processing of gas reduces regulation risks and the overall cost of possession. The intelligent functions allow for scalable maintenance strategies based on the actual condition of the equipment, which helps compensate for the shortage of qualified specialists and increases the reliability of assets.

Main characteristics and advantages of GM AirSeT

Insulation without SF

"GM AirSeT uses clean air as an insulating medium and vacuum technology to extinguish the electric arc, thus eliminating greenhouse gases and their associated toxic by-products. This ensures compliance with future environmental regulations, including Regulation (EU) 2024/573, and facilitates end-of-life equipment management processes," explained Schneider Electric Bulgaria.

Digital architecture

"Built-in sensors for monitoring tank pressure and tripping mechanism status allow for constant monitoring and maintenance based on the actual condition of the equipment. Through Schneider Electric's EcoCare services, this contributes to reducing unplanned outages by up to 75% and maintenance costs by up to 40%," the company also stated.

Compact and durable design

The solution is designed for high-power applications and harsh operating conditions. “The sealed tank and insulated busbars eliminate the need for on-site gas filling and ensure reliable operation in extreme temperatures, high altitudes and high humidity,” the specialists say.

Increased safety and operational efficiency

"Operators have intuitive interfaces, clearly defined logical control sequences, built-in safety interlocks, and remote and local control capabilities, allowing for safer operation outside the arc flash zone," the company added.

What makes GM AirSeT stand out?

The introduction of GM AirSeT to the market highlights Schneider Electric’s commitment to energy transition via sustainable, intelligent and orientated towards the future, technological solutions. GM AirSeT takes a key role in modernizing electro energy infrastructures, by allowing clients to meet their ecological and operational needs. “This is particularly important in demanding first-time applications where reliability, compact design, high power and digital functionalities are critical factors for reliable and efficient operation,” Schneider Electric emphasized.
