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, starting 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 installed at the data center’s main service entrance, typically in an outdoor substation. Due to their high capacity and cooling abilities, they 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, allowing maintenance 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.
- High voltage reliability: For core-form transformers of 25 kV or higher, we use disc windings to provide superior mechanical strength and manage electrical stress for long-term stability.
Expert Transformer Solutions for Your Data Center
We have designed various transformer services to meet all your power needs.
- Custom-built: Request a built-to-order dry type or oil-filled padmount transformer and we’ll meet your unique specifications.
- Emergency replacements: Our Quick Response Team will get your operations back up and running when you experience sudden failure.
- Transformer retrofits: Invest in a new transformer tailored to your space and the existing system’s power requirements.
- Custom bus work: We ensure that your new or replacement transformer connects seamlessly to your data center’s infrastructure.

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 quality materials, including 100% copper windings for dry type 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 back our products with team members who have over 20 years of experience, an industry-based five-year warranty on new dry types, emergency response within 24 hours and quick shipping. We also offer a three-year warranty on remanufactured dry type units.
