three phase dry transformerA full complement of three phase ventilated transformers from 3kVA to 300kVA and more We offer encapsulated three phase transformers from 3kVA through 9kVA and ventilated from 15kVA and up. Our enclosures are NEMA 3R without the addition of a costly weather shield as standard with only some exceptions at the smallest kVA which are indicated in the catalog.

 

 

Our transformers can be wall mounted or floor mounted cabinet style depending upon the kVA rating. These are UL and CUL listed and are copper wound through 9kVA although we offer copper designs on any of the products in the catalog. Our aluminum wound transformers start at 15kVA and extend through 225kVA as standard off the shelf. We also build larger custom transformers too.

 

In addition, we also offer TP-1 Energy Efficient Transformers starting at 15kVA and larger as required by the D.O.E. These transformers meet the minimum energy efficiency requirements as set forth by the Department of Energy in EPACT. TP-1 transformers begin with the prefix 43 for aluminum wound and 44 for copper wound transformers.

All of our transformers have an electrostatic shield between the primary and secondary for transient noise reduction. Insulation systems are 200° or 220° depending upon the series of transformer. Dongan Authorized Distributor
