ELSCO Transformers provides fast shipping for custom-built medium voltage transformers. Custom options include in-stock unit modifications for faster turnarounds and fully custom dry type and padmount builds for unique specifications.
- Custom transformer services: ELSCO Transformers designs and builds custom dry type and padmount transformers in the 500 to 4,000 kVA range, including custom bus work fabricated to match your facility’s existing gear.
- Custom transformer features: Every unit is hand-wound with copper windings and undergoes five-stage assembly testing before leaving the facility.
- Custom transformer lead times: Lead times depend on the scope of the custom build. In-stock unit modifications typically leave the facility within 24 to 48 hours, while fully custom builds ship once specifications are confirmed and fabrication is complete.
ELSCO Transformers designs, builds, and ships custom medium voltage transformers for a range of industrial and commercial applications across North America. Our engineering team is available by phone to answer questions and work through specifications before fabrication begins. Since 1988, we have had zero recorded product failures on new dry type transformers.
For in-stock unit modifications, many orders leave the facility within 24 to 48 hours, depending on the scope of work required. Fully custom dry type and padmount builds ship once specifications are confirmed and fabrication is complete.
Custom-Built Medium Voltage Transformers
We design and build customized medium-voltage units to order. Our custom-built transformer services include:
Custom-Built Dry Type Transformers
Custom-built transformer features for dry type units include air cooling and Nomex flame-resistant insulation, which makes them ideal for indoor use. If you need an outdoor power solution, you can also use a dry type transformer outdoors with a weathertight NEMA 3R enclosure. Our new dry type units have an industry-leading five-year warranty for indoor use.
Custom-Built Padmount Transformers
Liquid-cooled padmount transformers feature tamper-proof lockable doors, making them safe for use in public spaces. They do not require protective fencing to operate safely in an outdoor area. Our build-to-order padmount options are also more cost-effective because of their longer lead times, while our quick-ship options are better for failures or can’t-wait situations.
Custom Bus Work for Transformers
When you need the right connections to integrate one of our transformers into your system, consider our custom bus work service. We specialize in plug-and-play connections that make transformer installations seamless. You can combine our bus work services with a transformer purchase, retrofit or custom-build project.
Benefits of Our Custom-Built Transformers
When you order a custom-built transformer or retrofit unit with bus work from us, you’ll receive these advantages:
- Personalized design process: We begin every transformer design process with a detailed discussion with our clients. Our experts will pinpoint your needs and develop a solution that maximizes your investment.
- Local engineering: Each of our transformers comes from our warehouse in Cincinnati, Ohio. We take pride in our handcrafted manufacturing, free of automation.
- Industry-leading materials: All of our products feature the industry’s most trusted top-grade materials. With our dry types, we use copper conductors and Nomex insulation to deliver efficient, long-lasting results.
- Rigorous quality testing: Our engineers test each transformer multiple times throughout the manufacturing process. Our rigorous standards result in effective and reliable products.
Why Choose ELSCO Transformers for a Custom Build?
Few transformer companies in North America design, manufacture and stock their own copper-wound dry type transformers. ELSCO Transformers custom-built units are backed by the same craftsmanship and quality that have delivered reliable solutions for over a century. Here is what sets our capabilities apart:
- Top-quality engineering: We have a history of zero warranty issues or failures that goes back to our first dry type transformers in 1988. Our engineers ensure that each custom-built product has a reliable design with no shortcuts.
- Expert manufacturing and quality control: We hand-wind and assemble all of our transformers so that we can continuously check the placement, tension and clearances of the coils. This avoids faults and mechanical stresses that can cause hot spots and lead to premature transformer failure.
- Outstanding customer service: When you need technical advice or a rush order, count on our team for help. We will assist wherever we can to keep your operations running smoothly. Our engineers are available by phone 24/7 to answer your questions or help with installation issues.

Frequently Asked Questions About Custom-Built Transformers
Browse our FAQs below for answers to the most common questions we receive about custom transformer services, features and lead times.
How Does the Custom Design Process Work?
Every custom transformer order begins with a detailed discussion between the customer and an ELSCO Transformers engineer. Our team works through voltage, kVA and application requirements before fabrication begins, developing a solution built to your exact specifications.
What Are the Lead Times for Custom-Built Transformers?
Custom transformer lead times depend on the scope of the build. In-stock unit modifications typically leave the facility within 24 to 48 hours. Fully custom dry type and padmount builds require additional time for specification review and fabrication.
Can Custom-Built Dry Type Transformers Be Installed Outdoors?
ELSCO Transformers custom dry type transformers are designed for indoor use. Outdoor installation is possible with a weathertight NEMA 3R enclosure, but we recommend indoor installation for optimal safety and performance. For outdoor applications, custom padmount transformers are the most practical solution.
Why Do We Hand-Wind Transformers Instead of Using Automatic Equipment?
Hand-winding allows ELSCO Transformers technicians to continuously check coil placement, tension and clearances throughout the assembly process. Automated winding is less likely to catch the mechanical stresses that create hot spots in the coils, a leading cause of premature transformer failure.
