Our Selection of Transformers

We produce dry type and padmount transformers with the following features:

Dry Type Transformers

We manufacture dry type transformers for indoor environments because they are quiet and safe. The transformers use air to prevent coils, windings and insulation from overheating. We recommend installing these transformers in an enclosed space to protect them from unnecessary handling that may put either the installation or the handler at risk.

Each transformer comes with certain features that make it efficient.

  • Copper and aluminum coils that last long
  • Dupont Nomex and SG200 fiberglass that has outstanding longevity
  • Polyester varnish coating to protect coils from the risk of fire
  • Laminated steel cores that improve efficiency

Padmount Transformers

We have padmount transformers with ratings of 500 KVA to 2,500 KVA, with 4160, 12470, 13200, and 13800 volt primary voltages. They’re suitable for outdoor spaces in hospitals, universities and large facilities close to underground electric power lines. We build custom padmount transformers for facilities that have unique features. Padmounts are different from dry type transformers because they use oil in the cooling process.

We can also work with you to modify or fabricate customized padmount transformer units to meet your requirements. For example, If you need a padmount transformer with a custom bushing height, we can build a new unit to order, or we can use copper bus drop-downs on the low-voltage bushings for one of our in-stock units.
