Their ability to offer certified components, lifecycle support, and streamlined procurement processes has increased buyer confidence and adoption rates.
As data center operators seek end to end power solutions with built in compliance and efficiency features, OEMs continue to lead the market with scalable and future ready transformer technologies.
Demand for data center transformers is intensifying as hyperscale and edge facilities scale up power density. Sales of dry-type and liquid-immersed transformers are rising due to grid-resilience needs, renewable integration, and redundancy-focused power infrastructure investments.
Demand for data center transformers rated above 2.5 MVA grew 21% in 2025, led by hyperscale projects in the USA, Ireland, and Singapore. Operators are deploying oil-immersed transformers with dual secondary windings to meet Tier IV uptime standards. Modular liquid-cooled designs are enabling higher rack densities without thermal compromise. Data center developers in the Middle East adopted 66kV–132kV primary transformers for direct-to-grid access, bypassing substation bottlenecks and reducing latency. Load balancing via smart tap changers has reduced peak power penalties by 14%. Redundant transformer arrays are now embedded into prefabricated power skids, accelerating deployment timelines by 29% in colocation buildouts.
Sales of dry-type data center transformers jumped 26% in 2025, driven by edge computing growth and indoor deployment constraints. Air-insulated cast resin units below 2 MVA gained traction in urban micro data centers and telecom switching hubs. Operators prefer low-fire-risk, low-maintenance units for colocated environments, especially in high-rise retrofits across Asia-Pacific. Smart monitoring on dry-type transformers enabled real-time core temperature tracking, cutting reactive maintenance costs by 17%. OEMs are now bundling dry transformers with UPS bypass switches and voltage regulation modules, creating plug-and-play packages for 5G data edge rollouts. This segment is seeing fast conversion from diesel genset-reliant backup systems.
