What we source
General purpose low voltage
Up to 600 volts, built to UL 1561, for example 480 delta to 208Y/120 to feed lighting and receptacle panels. Distribution units are subject to US DOE efficiency rules.
Medium voltage dry type
Above 600 volts, built to UL 1562 and IEEE C57.12.01, used in unit substations inside buildings.
Cast resin
Windings cast in epoxy, used where moisture, contamination or fire risk rule out other designs.
Buck boost, isolation, K rated and drive isolation
Specialty dry type units for small voltage corrections, electrical isolation, nonlinear loads and motor drives.

Common questions
When should I use a dry type transformer instead of oil filled?
Indoors, where codes and insurers prefer no liquid, and at smaller ratings. Outdoors and at larger ratings an oil filled pad mounted transformer is usually smaller, more efficient and cheaper.
