ELSCO Transformers manufactures and sells high-quality oil-filled padmount and dry type transformers for data centers. With superior materials and meticulous quality control measures, we build systems that meet the specific needs of data centers.
Explore High-Quality Medium Voltage Transformers
We stock IEEE-, ANSI-, DOE- and NEMA-compliant medium voltage transformers in several ratings, from 500 kVA to 3,750 kVA. Shop our existing catalog or request a built-to-order unit.
Padmount Transformers for Data Centers
Oil-filled padmounts are located at the data center’s main service entrance, typically in an outdoor substation. Due to their high capacity and cooling capabilities, these transformers perform the initial voltage step-down before it enters the data center.
We build our oil-filled transformers to provide:
- Zero-downtime fluid testing: The external drain valve allows for online fluid analysis, as maintenance can be done without opening the main compartment.
- Flexible system integration: We offer a choice between dead-front connections for increased employee safety and standard live-front designs.
- Two configurations: For your system layout, select a loop-feed configuration for enhanced reliability or the cost-effective radial feed for simpler installations.
Dry Type Transformers for Data Centers
Dry type transformers are often used inside data center buildings and within power distribution units (PDUs) to perform a secondary voltage step-down. They are valued for their fire safety and low-maintenance capabilities.
Our engineering focuses on the precision and efficiency your data center demands.
- Better fire safety: Primary and secondary windings feature fire-resistant Nomex insulation, a nonnegotiable safety feature that reduces the fire risk associated with liquid-filled indoor systems.
- Reliable power delivery: Our sheet winding method provides superior mechanical strength, reducing the risk of transformer failure.
- Exceptional reliability: For 25 kV and above core-form transformers, we use disc windings to provide superior mechanical strength and manage electrical stress for long-term stability.

Discover What Sets Us Apart
ELSCO Transformers builds medium voltage transformers that deliver the continuous power required to maximize uptime and protect your critical loads and sensitive equipment.
Our partnership offers:
- Zero-failure reliability: Our meticulous manufacturing has resulted in zero reported failures on our dry type transformers since 1988, giving you peace of mind.
- Optimized data center load: Hand-wound and assembled with materials of the best quality, including 100% copper windings for our dry type transformers and copper or aluminum for padmounts, our transformers handle the continuous, high-density power demands of server racks for a service life of 35 years or more.
- Lower PUE: Because our transformers exceed the latest DOE standards, they lower your power usage effectiveness (PUE).
- Ongoing support: As your partner in continuity, we stand behind our products with team members who have over 20 years of experience, an industry-best five-year warranty on new dry type transformers, emergency response within 24 hours and quick shipping. We also offer a three-year warranty on remanufactured dry type units.
Transformer Solutions for Data Centers FAQs
Got questions about the right transformer solution for your needs? Here are some of the questions we get most often to help you make an informed choice.
What type of transformer does my data center need?
The type of transformer your data center needs depends on your load, location, available space and cooling needs. Common data center transformer types include padmount oil-filled transformers for outdoor use and dry type transformers for indoor use. When you’re comparing padmount vs. dry type transformer options, also consider delivery access and future maintenance.
What transformer sizes and kVA ratings do you offer for data centers?
At ELSCO Transformers, we offer medium-voltage transformers ranging from 500 kVA to 3,750 kVA. Our available transformers include both a wide range of catalog models and custom builds made to fit exactly what you need. Our team can match your transformer specifications, including voltage, capacity, connection and layout requirements.
Can transformers be serviced without shutting down the data center?
Some transformer services can be completed without needing to shut down the data center. For example, you can do zero-downtime testing on our oil-filled padmount transformers thanks to an external drain valve, which lets fluid analysis to be performed without opening the main compartment. Other maintenance may still need the data center to be shut down for safety purposes.
What happens if a transformer fails?
If a transformer fails, power distribution to servers, cooling systems and other critical equipment gets interrupted. The facility may face reduced capacity, overheating risks or downtime if the power isn’t restored quickly, which can cause the business to lose money. The exact impact depends on the transformer’s role, system redundancy and available backup power. Depending on its condition, the transformer may need to be repaired, rebuilt, retrofitted or undergo an emergency transformer replacement.
How quickly can ELSCO respond if a transformer fails?
We offer 24-hour service through our Quick Response Team for transformer failures that need to be fixed fast. The exact timing of an emergency transformer replacement or repair depends on the availability of the transformer, any modifications it needs, shipping distance and your existing system’s specifications.
Does ELSCO offer custom-built transformers for unique data center layouts?
Yes, we offer built-to-order transformers for unique data center layouts and electrical requirements. Our engineering team can make custom transformers tailored to the dimensions, voltage, kVA rating, connections and bus work you need to match your infrastructure and transformer specifications.
