Global Vacuum Insulated Switchgear Market size was valued at USD 87.0 Billion in 2024 and is poised to grow from USD 93.0 Billion in 2025 to USD 158.61 Billion by 2033, growing at a CAGR of 6.9% during the forecast period (2026-2033).
Vacuum insulated switchgear, abbreviated VIS, is compact metal enclosed medium voltage equipment that uses vacuum interrupters to interrupt currents in distribution networks, and its primary driver is the growing requirement for space efficient, safe, and environmentally preferable solutions in increasingly dense urban power systems. The market matters because utilities, industries, and transit operators demand higher reliability while reducing footprint and lifecycle costs. Over time the industry moved from traditional air insulated breakers through SF6 gas insulated systems to modular vacuum based assemblies, and real world shifts include European urban substations reclaiming land and Asian metro projects installing tunnel rated VIS.
The key trend driving the global vacuum insulated switchgear sector growth is tightening environmental and safety standards, which limit SF6 use and favor low GWP alternatives, because regulatory mandates compel utilities to choose insulation options with simpler handling and lower lifecycle emissions. Consequently manufacturers increase vacuum interrupter research and scale production, which reduces unit costs and broadens suitability for retrofit and new installations. Evidence shows that this cause & effect pattern generates significant opportunities like quickening replacement programs throughout all of Europe and compact substations for electric vehicle charging corridors across North America along with the use of VIs in offshore wind collection systems, which will reduce maintenance costs, total operating costs and payback times.
How is IoT Enhancing Asset Monitoring in the Vacuum Insulated Switchgear Market?
Vacuum insulated switchgear benefits from IoT by changing its originally passive nature into an actively connected asset that reports the conditions of its health and performance. A few key aspects within this category of switchgear include: the ability for partial discharge sensing; thermal and humidity monitoring; and the collection of secure edge data. Currently, there is a trend toward compact, SF6-free designs that are digital ready and desirable for utilities that prefer reliable and lower lifetime costs. Typically, deployments of vacuum insulated switchgear will utilize UHF partial discharge sensors in addition to temperature sensors, with local analytics, resulting in utility teams being able to anticipate trends and avoid failure before it happens.
In August 2025, Siemens Energy successfully tested a 420 kV SF6 free circuit breaker prototype that relies on vacuum switching and is slated for pilot installation in transmission systems. IoT enabled sensing and cloud analytics turn test data into actionable alerts and speed adoption by improving diagnostics and maintenance planning.
