A medium voltage switchgear may not be the most visible part of the energy system, but it’s one of the most critical. Traditionally seen as a passive mechanical asset, medium voltage switchgear is now experiencing a transformation in perception.
ABB conducted a survey of electrification decision-makers across Europe. Two major themes emerged amongst the switchgear purchase decision makers: the growing need and appetite for automation, and increasing regulatory pressure — particularly around sustainability and the use of sulfur hexafluoride (SF₆). Together, these themes are accelerating the shift toward smarter, more connected and sustainable switchgear solutions.
As the energy transition gathers pace, electrical distribution networks are becoming more complex. Utilities and industries alike are under pressure to maintain stability and safety while integrating new energy sources, responding to rapid shifts in demand, and minimizing downtime.
That’s why two-thirds of survey respondents cited automation as a strategic priority for the next 1–2 years. Yet only 13 percent currently use fully digitalized switchgear — highlighting a major opportunity for improvement. However, clarity is needed. Digital switchgear generally refers to equipment that integrates digitally enabled components — such as smart protection relays, sensors, and communication interfaces — to enhance monitoring, control, and diagnostics. In critical environments, this directly translates into improved uptime and operational efficiency.
At ABB, we’ve been investing in these capabilities for years. Our medium-voltage switchgear solutions, including digitally enabled components such as intelligent protection relays and embedded condition monitoring systems, help customers build resilience into their infrastructure.
Decarbonization is another major driver of switchgear evolution.SF₆ is a potent greenhouse gas with a global warming potential over 24,300 times greater than CO₂. According to our survey, 83 percent of decision-makers would only move to SF₆-free technologies if required by regulation. Worldwide regulatory requirements are evolving fast — and several countries are already moving to ban SF₆.
That’s why we’ve developed solutions insulated with dry air. ABB was recently selected by E.ON, Germany’s largest distribution system operator, to supply its next-generation SF₆-free switchgear. This partnership will help E.ON meet the forthcoming EU F-gas regulation banning SF₆ in new medium-voltage equipment. ABB’s SafeRing and SafePlus Air units, chosen for this project, demonstrate how early adoption and trusted collaboration are enabling utilities like E.ON to take a leading role in the energy transition.
