Dongan Electric Manufacturing Company - Manufacturing transformers and inductors with speed, precision and flexibility

Dongan Electric Mfg. Co. specializes in the manufacturing of single and three phase transformers, chokes and inductors and other related magnetics. We can wind in aluminum or copper magnet wire and we have access to numerous grades of high quality lamination steel.

Dongan's Capabilities:

Our product scope is broad in terms of products offered and range of sizes. We offer three phase isolation or auto transformers, single phase isolation or auto transformers. Single or three phase reactors, industrial control transformers, drive isolation transformers, K-factor transformers, DC rectified transformers. We are vertically oriented manufacture and consequently do most of our manufacturing in house, allowing us to shorten the supply chain. We also design and build our own enclosures and can meet NEMA 1, 3R, 4, 4X and 12 requirements.

We are very strong in kva ranges from as small as 1kva through 3000kva. But do also manufacturer products much larger and smaller than these sizes.

One of core strengths is our ability to manufacture products that fit the customer's requirements at any time. So while other manufacturers try to offer a cookie cutter solution and force a square peg in a round hole, we make a round peg. Dongan creates over 600 new designs per year many can be a one off design and we do them quickly typically in three weeks or less. Why try and settle for something that may when we can give you what you need for your application. Of course we also handle the larger orders with multiple units required.
