Wound magnetic cores have been used in the design and manufacture of distribution, small power and instrument transformers for over 50 years.

Since 1974 TRANCO has been serving the transformer industry, fostering a worldwide reputation for superior product designs and customer service.

The TRANCO Core Winding Machine automatically produces wound cores using a continuous feed process.  As a result, the wound core becomes more desirable to produce than the less efficient "cut and stack" core.

With adjustable machine settings customers are able to produce a wide variety of consistent gap patterns to their desired specifications.
