Grounded in Reliability

When the power goes out you’ve got a problem.

Total-Lifetime-ValueAs one of the first transformer repair shops in the U.S., The Electric Service Company is a leading provider of quality dry type transformers and padmount transformers. We manufacture the most advanced power transformers available, providing continuity through the lifetime value of each unit.

Established in 1912 by two Westinghouse engineers, ELSCO Transformers delivers the highest quality and most reliable power transformers on the market.

What’s the ROI for a Lifetime of Quality?

If you’re considering a new or replacement dry type or oil-filled padmount transformer, we understand cost is a crucial factor in your decision. An investment in the lifetime value of a transformer may be slightly higher on the front end, but delivering uninterrupted power for commercial and industrial needs is worth it.
