2,500 kVA Medium Voltage Dry Type Transformers

ELSCO Transformers builds medium voltage 2,500 kVA dry type transformers by hand using 100% copper windings and the highest-rated insulation materials available. This commitment to quality prolongs the system’s service life and lowers the total cost of ownership. Our 95% in-stock availability makes emergency replacements quicker, while our engineering capabilities enable us to retrofit or custom-build your unit to your specifications. With our quick-ship option, your 2,500 kVA dry type transformer can leave our facility within 24 to 48 hours, depending on what modifications need to be made.

2,500 kVA Dry Type Transformers: Overview and Features

We engineer our devices for the demands of continuous, high-capacity operation. At 2,500 kVA, marginal iron losses can compound substantially over the full service life of your system. With a step lap mitered core, your investment can hold iron losses to a minimum at partial and full load, minimizing your annual energy costs.

We hand-build our transformers with copper windings, which conduct electricity better than aluminum and are more durable. Other features include:

• Insulation rated for the thermal demands of high-capacity operation: At 2,500 kVA, thermal buildup is the primary failure risk. DuPont Nomex at 200° Celsius and SG200 fiberglass insulation materials provide dielectric stability and heat resistance to protect coil integrity across years of sustained load.
• Verified performance at five manufacturing stages: We test our solutions after low-voltage winding, high-voltage winding, core stacking, bus bar assembly and varnish curing. This strict quality process means our transformers consistently register a power factor of approximately 0.3% compared to the 1% industry requirement. We have not had a warranty claim for material, design and workmanship failure since we started building our dry type transformers in 1988.
• Quiet, low-vibration operation: Anti-vibration pads and a tight mechanical assembly minimize acoustic output and vibration, supporting quiet performance.

Plug-and-Play Installation for Retrofits

A misaligned connection or an enclosure that doesn’t fit can add days of unplanned downtime to an already complex installation. We engineer against that risk before your investment leaves our facility. Our team reviews your existing enclosure dimensions, electrical connections and infrastructure layout to deliver a 2,500 kVA transformer that is ready for installation. Where custom bus work is needed, we can build bus bars for your system. Our engineers are also available by phone 24/7 to answer your installation questions.

Common Applications for 2,500 kVA Transformers

The 2,500 kVA rating serves facilities where load volume, operational continuity and the cost of downtime are all at their highest. Examples include:

• Primary metals processing and steel manufacturing: Our solutions meet the sustained high-ampere output of smelting, casting, and rolling operations.
• Large petrochemical and refining operations: Our systems provide stable step-down capacity for distributed process equipment in fire-sensitive environments where dry type construction is operationally required.
• Large hospitals and regional medical centers: A 2,500 kVA transformer sustains the critical power demands of multiple departments, such as operating rooms and intensive care units.
• Regional utility switching stations and government operations facilities: Our solutions serve large, mixed-load institutional systems that require 24-hour operational continuity.
