Transformers for Data Centers Supporting the Digital Transformation
From hyperscale campuses to edge facilities, data centers are the backbone of the modern economy and every rack, row, and cooling system depends on reliable power. MGM Transformers designs and manufactures transformers for data centers that keep mission-critical loads online, delivering the voltage regulation, efficiency, and uptime that 24/7 operations demand. For decades, we have partnered with developers, EPCs, and facility operators to power hyperscale, colocation, and edge deployments across the United States. As AI, cloud, and high-density computing drive power demand to record levels, operators need transformer capacity that can be deployed quickly and scaled with confidence without ever compromising reliability.

Transformers in Data Center Electrical Infrastructure
Within the data center electrical infrastructure, transformers sit at nearly every step of the power chain, by stepping medium-voltage utility service down to the levels used by switchgear, busway, UPS systems, and power distribution units (PDUs). Many modern facilities take service at medium voltage and distribute it before stepping it down close to the load. This means that transformer selection directly affects both resilience and total energy cost. Because a single interruption can take everything offline, this infrastructure is built around redundancy (N+1, 2N) and tight voltage regulation. The transformer is a critical link in keeping that power clean and continuous.
MGM Transformers data center units are engineered for continuous, high-load duty: low losses that reduce heat and energy cost, robust thermal design for dense electrical rooms, and configurations that integrate cleanly with the rest of your distribution equipment. Whether you are feeding a hyperscale data hall or a compact edge node, the right transformer holds power quality stable all the way from the utility feed to the server.
Key Technical Considerations for Data Center Transformers
Specifying a transformer for a data center is about matching the unit to the facility’s load profile, layout, and growth plan. Key factors our engineering team helps you evaluate include:
- kVA rating: Sizing the transformer to present load plus planned expansion, so the capacity is there when you scale up.
- K-factor requirements: Handling the harmonic currents generated by servers, UPS systems, and other non-linear IT loads without overheating.
- Enclosure size and footprint: Fitting the unit into tight electrical rooms, mezzanines, or outdoor pads.
- Primary and secondary connection points: Aligning terminations with your busway, breakers, or cable entry to simplify installation.
- Voltage configuration: Matching primary and secondary voltages to the utility feed and downstream distribution equipment.
Our Data Center Transformer Solutions
MGM Transformers offers a range of data center transformer solutions for both indoor and outdoor installations. Our Dry Substation (VPI) transformers are a clean, low-maintenance choice for indoor electrical rooms and mission-critical spaces where fluids are a concern, while our oil-filled padmount compartmental transformers deliver high efficiency and rugged performance for outdoor and campus-style deployments.
Need a different form factor? We also build cast coil and custom distribution transformers, and our team supports both new builds and capacity upgrades to existing facilities. Every unit is custom-engineered to your specifications and backed by U.S. manufacturing and responsive support including emergency replacement through our Bull Rush Program. Contact us to discuss your facility’s requirements and get a quote tailored to your data center project.
Data centers typically use dry-type and oil-filled distribution transformers to step utility or generator voltage down to the levels needed by switchgear, UPS systems, and PDUs. Dry-type units (such as VPI) are common indoors and in mission-critical rooms because they use no liquid coolant, while oil-filled padmount transformers are often used outdoors for higher efficiency and capacity. The right choice depends on location, load, and fire and maintenance requirements.
Dry-type transformers cool with air and contain no flammable liquid, which makes them well suited to indoor electrical rooms and spaces where fluid containment is a concern; they are typically lower maintenance. Oil-filled transformers use a coolant that allows higher efficiency and load capacity in a smaller footprint, and are usually installed outdoors on pads. For data centers, dry-type is common indoors and oil-filled is common for outdoor and campus deployments.
Lead times vary with size, configuration, and market demand, and can range from a few weeks for stocked or standard units to several months for fully custom designs. Because data center schedules are tight, MGM Transformers manufactures in the U.S. and offers expedited delivery, through our Bull Rush Program, to keep projects on track. Contact us with your specifications for a current lead-time estimate.
Yes. Our Bull Rush Program is built for emergencies: we work around the clock until your emergency transformer is delivered, or your money back. For mission-critical data centers where downtime is not an option, this rapid-response manufacturing helps restore redundancy and keep operations online.
Yes, unless a specific unit type is exempt. MGM Transformers designs and manufactures transformers to meet applicable U.S. Department of Energy (DOE) efficiency standards and relevant industry specifications. We can provide the documentation and efficiency data your design and commissioning teams need for compliance and for sustainability reporting.
Transformers run continuously, so even small efficiency gains reduce electrical losses that show up as heat and wasted energy, both of which affect PUE. High-efficiency, low-loss transformers cut conversion losses and the cooling load needed to remove that heat, supporting a lower PUE. The transformer is one of many factors in overall PUE, but specifying efficient units is a practical way to improve energy performance over the life of the facility.
