Transformer Service and Maintenance Capabilities

ELSCO provides and services dry type and padmount transformers. We use the latest technology and durable materials for every system we build or maintain so that you have a reliable energy output source whatever your application. Services we offer include:

General Repairs

Is your transformer failing due to wear and tear? If so, we offer medium voltage transformer repairs that can keep almost any system running longer. With regular transformer maintenance, you can ensure significant issues won’t interrupt your daily routines, and we’ll return your unit to pristine condition. Our engineers, winders and shop leaders work together as an experienced team to offer transformer repair services with results that outlast those of competitors — sometimes for decades.

Emergency Replacement Services

If a sudden transformer failure brings operations at your facility to a halt, we offer emergency replacement services to help you get back on track. These days, it is common — and often more logical — to replace a transformer rather than repair it so you can take advantage of the advanced features of newer models.

ELSCO Transformers stocks a large selection of dry type and padmount transformers in various kVA ratings and voltages, and we’re ready to offer you fast emergency replacement services at a moment’s notice. We dispatch all transformer parts within 24 to 48 hours, depending on which modifications we need to make. Our response time for emergency replacements is typically 24 hours or less, allowing major businesses to reduce downtime and expenses. Call (800) 232-9002 if you have an emergency.


Our oil-filled and dry type transformer services come with a variety of retrofitting options. We’ll replace your old transformer with a new, customized unit to meet your unique needs. With the future in mind, we will retrofit your transformer, ensuring your system can meet increased capacity requirements. This means that if you need custom bus work on a dry type to match up with your high-voltage and low-voltage gear – we’ve got you covered, as that is our specialty. We can retrofit your transformer with our new dry type or padmount stock units or custom-build a unit for your facility.


When a system needs more than a simple repair, we have the resources to rebuild your transformer completely. ELSCO rebuilds consist of new windings and new oil, gauges and bushings if needed. We make sure everything fits all your previous specifications.


Sometimes, a transformer coil can fail due to moisture or other significant issues. If your existing wire is worn out or damaged, but the rest of your system is in fine working order, opt for a rewind. Our expert winders can replace your transformer coil or add new wires with different specifications to better meet your needs.

Custom Builds

Looking to build a transformer system from the ground up? If we don’t stock a transformer that meets your voltage requirements, we can build a customized unit that will. Along with purpose-built dry type and padmount transformers, we provide custom bus work to make your unit ideal for specific requirements.

ELSCO works with manufacturing facilities, hospitals, utility companies and more to provide fast, individualized transformer service.
