Replacing a medium voltage dry type transformer can quickly become complicated when the new system’s connection points don’t align with your facility’s existing electrical infrastructure. ELSCO Transformers solves that problem by fabricating and installing custom bus bars on your new transformer before it leaves our facility. The result is a design configured precisely for your connection points and ready to connect without extensive on-site work.
When Custom Bus Work May Be Needed
Custom bus work is often needed in the following situations:
- Replacing an old transformer with a new one: Replacing your transformer with a different or newer model can prove costly because it may require you to rework all the connections to and from the transformer. This becomes an urgent problem in emergency replacement situations, where a few additional hours of downtime can exceed the price of a new transformer.
- Upgrading your facility’s power capacity: When your plant or facility needs to increase energy production or capacity, or you need to replace an existing dry type, you may have to alter infrastructure to meet your goals. To save money while upgrading, many facility managers turn to new retrofit transformers. These custom systems can provide greater power capacity while maintaining the connections and dimensions of the original.
At ELSCO Transformers, we can provide custom bus work for our dry type transformers in replacement or retrofit applications. For a perfect fit, our staff will make sure the new low voltage bus bars line up with your facility’s existing low voltage gear and include any necessary high-voltage cabling to the high-voltage gear. When you provide the specifications, we can equip your ELSCO medium-voltage dry type transformer with the right bus bar arrangement already in place. We guarantee a perfect fit to your specs.
Benefits of ELSCO Custom Bus Work
ELSCO Transformers provides custom bus work to:
- Solve unique challenges: Custom bus work will allow you to equip a retrofit transformer with connections that accommodate your space. You can use our custom bus work services to connect a motor control center (MCC) to the transformer, share regenerative drive energy and more.
- Simplify the installation process: Retrofit transformers with custom bus work are designed to fit in the space your old transformer occupied. You won’t need to rework any connections or build new enclosures, which will save time and money during installation.
- Reduce the cost of upgrading: Retrofit transformers reuse some of the hardware you already have, lowering the cost of upgrading your facility’s infrastructure.

Custom Bus Work Frequently Asked Questions
Not sure if custom bus work is right for your facility? Find answers to the most common questions we receive below.
What if I’m Unsure About the Type of Bus Work My Transformer Needs?
If you’re unsure about your bus work requirements, our engineering team can help you identify the right solution. We’ll ask for photos of your existing transformer and electrical setup, along with key measurements and specifications for your connection points. From there, our engineers will assess your situation and recommend the most practical solution.
How Quickly Can ELSCO Complete Custom Bus Work?
Turnaround time depends on the complexity of your specifications, but many custom bus work orders leave our facility within days of your request. Our team will walk you through each phase of the process and keep you updated on your order’s progress every step of the way.
What Is the Difference Between a Transformer Retrofit and Custom Bus Work?
A transformer retrofit is the broader process of modifying an in-stock unit to match your facility’s physical dimensions and specifications. Custom bus work is a specific element of that process focused on fabricating and installing bus bars to align with your existing connection points and low voltage gear. Depending on your requirements, custom bus work may be completed as part of a retrofit or as a stand-alone service.
What Types of Connections Can ELSCO Accommodate With Custom Bus Work?
ELSCO can accommodate a range of connection types, including low voltage bus bar configurations that align with your existing low voltage gear and high voltage cabling to your high voltage gear. Our engineers can also configure bus work for motor control center connections and other specialized applications. Our team can answer questions about your application’s specific requirements.
