3-Phase Transformers

There are several advantages to using three-phase transformers, including the following:

1. Three-phase transformers use less material, weigh less, and are more compact than single-phase bundles. 

2. Three-phase transformers increase reliability. 

3. Three-phase electricity powers large industrial equipment more efficiently than single-phase electricity. 

4. Three-phase power can be transmitted over long distances with smaller conductor size.

How 3-Phase Converters Work

Three-phase transformers are constructed by winding three single-phase transformers on a single core, which is then put into an enclosure filled with dielectric oil.

Because the dielectric oil does not conduct electric current, it provides insulation between the winding and the enclosure. The dielectric oil also acts as a coolant, and helps prevent moisture that can deteriorate the winding insulation.

There are more than 150 manufacturers and distributors of 3-phase transformers, many of which will custom build according to your specifications.
