Renewing your transformer and ensuring it is in the best possible condition for company use

There is no set standard when it comes to repairing or reconditioning a transformer. That means a lot of different things. Some companies just dust it off and re-sell it to you without checking it over for worn out components.

ELSCO examines and tests the transformer to identify any worn-out components. We replace old parts with new ones. Then we re-varnish the transformer so that it looks and runs like new.

Repair Services

Whether it’s an emergency or not, ELSCO is the leading provider of transformer repairs.

We’ll repair, rebuild, or replace your dry-type, padmount or substation transformer. Contact us at (800) 232-9002 for emergency service.

When your transformer needs to be repaired, you may not have a lot of time to shop around.

As the original transformer repair facility in the U.S., ELSCO has rebuilt, repaired, or sold over half a million transformers, since 1912. We specialize in delivering transformer repair service to commercial and industrial customers with transformers rated up to 10,000kVA and 69kV.

The expertise we deliver to commercial customers is based on the experience of our staff. ELSCO’s chief engineer has worked in the industry for over 40 years. Our chief winder has over 30 years’ experience and our shop foreman has been in the industry for more than 20 years. Our seasoned team has repaired or replaced every make and model of transformer on the market.

All transformer rewinds are done using copper windings (HV & LV) to provide additional insulation or cooling ducts as appropriate for a long-lasting rewind.

ELSCO provides 24-hour response time on most major repairs. Since repairs on most transformer models typically take four weeks to turnaround, we offer emergency replacement transformers to minimize the interruption to your business and your productivity.

Reconditioned Transformers

Are you interested in finding the highest quality reconditioned or remanufactured transformers on the market?

ELSCO maintains an inventory of hundreds of pre-owned copper-wound dry-type and oil filled transformers available to purchase or rent. The benefits of buying a reconditioned transformer include cost efficiency, expediency, and reliability.

Due to our nation-wide service area, we’re constantly acquiring previously owned transformers, which we put through a comprehensive certification process before making them available to you. Our team of engineers inspect, clean, and refurbish all units, before certifying all products and adding to our catalog.

ELSCO’s line of certified, pre-owned transformers run from 500 kVA thru 2500 kVA with 2.5, 5, and 15 kVA primaries. All units can also be modified to match your existing line-up and include a one-year warranty on all parts and performance, so you’re assured of the same reliable quality found in a new transformer.
