Commercial & Industrial Transformers
From manufacturing plants and warehouses to hospitals, office buildings, and water treatment facilities, commercial and industrial operations depend on reliable power infrastructure to keep running. Industrial transformers are a critical part of that infrastructure, stepping voltage up or down at every stage of the power distribution chain, from utility entry to the equipment on the floor.
MGM Transformers has been supplying commercial and industrial transformers to contractors, facility managers, and EPCs across the United States for more than 50 years. As a leading transformer manufacturer, we combine custom engineering capability with fast delivery programs to make sure your project stays on schedule, no matter the application.

Industrial Transformer Applications by Sector
Commercial and industrial facilities each have distinct power requirements. The right transformer depends on the environment, load type, voltage configuration, and installation constraints. MGM Transformers serves a wide range of sectors with transformers engineered for each application.
Manufacturing & Industrial Plants
Manufacturing facilities operate heavy machinery, motors, and process equipment that demand consistent, uninterrupted power. Industrial electrical transformers used in these environments must handle high load cycles, harmonic-rich environments, and demanding duty requirements. MGM Transformers’ Dry VPI Substation and cast coil transformers are well-suited for the voltage regulation and durability that plant operations require.
Commercial Buildings & Real Estate
Office towers, retail developments, mixed-use buildings, and corporate campuses require step-down transformers to distribute power from utility service to usable building voltage. MGM Transformers’ general purpose low voltage transformers and padmount transformers are stocked across 20 major US cities, supporting fast-paced construction timelines for commercial real estate projects.
Hospitals & Healthcare Facilities
Power interruptions in healthcare environments are not an option. Hospitals require transformers that are fire-resistant, low-maintenance, and reliable under continuous load. MGM Transformers’ cast coil transformers, with their solid epoxy resin insulation and oil-free design, are an ideal fit for indoor healthcare installations where safety and uptime are the top priorities.
Warehouses & Logistics Centers
Distribution centers and large-scale warehouses require efficient power distribution across wide footprints, often with outdoor transformer installations. MGM Transformers’ oil-filled padmount transformers are built for ground-level outdoor deployment, with tamper-resistant enclosures and flexible configuration options to support the power demands of modern logistics operations.
Municipalities & Water Treatment
Water treatment plants, pumping stations, and municipal facilities require transformers that perform reliably in demanding environments with minimal maintenance. MGM Transformers supplies dry-type and padmount transformers that meet US regulatory standards and are built to withstand the continuous duty cycles common in municipal infrastructure.
Commercial & Industrial Transformer Solutions
MGM Transformers offers a full range of transformer types for commercial and industrial applications. Each product is engineered to meet the specific voltage, environmental, and performance requirements of the project.
Dry VPI Substation Transformers
MGM Transformers’ Dry VPI substation transformers are built for medium-voltage indoor applications where performance, longevity, and environmental safety are essential. Rated from 500 kVA to 10,000 kVA and 600V to 34.5kV, these units are DOE 2016 efficiency compliant and UL/CUL listed. VPI coils provide strong resistance to moisture, dirt, and industrial contaminants, making them a dependable choice for manufacturing facilities, commercial substations, and industrial power distribution systems.
Cast Coil Transformers
MGM Transformers’ cast coil transformers are designed for environments where fire safety, moisture resistance, and low maintenance are critical. With windings fully encased in epoxy resin insulation and no liquid insulation, these transformers eliminate leak risk and reduce environmental exposure. They are well-suited for hospitals, schools, underground installations, and any commercial or industrial facility where indoor safety standards are stringent.
Oil-Filled Padmount Transformers
MGM Transformers’ oil-filled padmount transformers are built for outdoor, ground-level power distribution in commercial and industrial settings. Supporting applications up to 10,000 kVA and 34,500V, these units feature tamper-resistant, pad-lockable enclosures and sealed tanks for long-term outdoor performance. Available in single and three-phase configurations with a wide range of optional features including load-break switches, metering, and forced air cooling.
General Purpose Low Voltage Transformers
MGM Transformers’ general purpose low voltage transformers deliver reliable power distribution for a wide range of commercial and industrial applications. DOE 2016 efficiency compliant and UL listed, these units are stocked in over 20 major US cities for fast project delivery. Available in standard configurations from 15 kVA to 750 kVA, as well as custom-engineered designs for non-standard voltage combinations, special enclosures, and unique winding requirements.

Commercial and industrial buildings typically use dry-type transformers for indoor applications and oil-filled padmount transformers for outdoor power distribution. Inside the building, general purpose low voltage transformers step 480V down to 208V or 120V for equipment and lighting. For medium-voltage applications, dry VPI substation or cast coil transformers are used at the point of utility entry or within electrical rooms.
Dry-type transformers use air and solid insulation materials such as epoxy resin instead of liquid, making them safer and lower maintenance for indoor commercial and industrial installations. Oil-filled transformers use mineral oil for insulation and cooling, allowing them to handle higher capacities and making them better suited for outdoor, high-load applications such as utility entry points, warehouses, and industrial sites.
The right kVA rating depends on your facility’s total connected load, demand factor, and growth projections. Commercial buildings typically use transformers ranging from 15 kVA to 500 kVA for floor-level distribution, while large industrial facilities may require medium-voltage substation transformers rated from 500 kVA to 10,000 kVA. MGM’s engineering team can help size the right unit for your application.
Yes. All MGM transformer product lines, including Dry VPI substation transformers, cast coil transformers, and general purpose low voltage transformers, are DOE 2016 efficiency compliant.
