At Maddox Industrial Transformer we are dedicated to reconditioning transformers and redeploying them to power on our customers’ projects: from data centers and EV charging stations, to shopping malls and solar farms. With shops and offices across the United States, we stock the largest selection of new and reconditioned transformers with the shortest lead times in the industry. We have thousands of new and reconditioned units in stock, ready to ship at a moment’s notice.

We work with small one-man operations, all the way up to the largest industrial projects in the country. Our customers value speed, transparency, and an easy buying experience.
