Specialty Transformer Manufacturing

Southwest Electric’s Specialty Transformer plant designs and builds custom transformers to meet your application needs.

Some of our common designs include:

Multi-Tap Transformers

Designed for surface pumps, submersible pumps, and variable speed drive applications.

Poly-Auto

Polygon autotransformer designed to supply a twelve-pulse motor drive.

FACT Transformers

Single phase transformers with full amp capacity across a wide, externally selectable, secondary tapping range. The FACT transformer is available with a dual primary voltage.

Skid Mounted Transformers

The skid packages are designed for the quick set-up or relocation of the transformer and equipment package. The package can include a protective enclosure, a conditioned control room, switchgear, metering, reactors, lightning, and other desired features.

Phase Shifting Transformers

Reduce the need for expensive harmonic filters with use of these transformers.

ZT-Fact

A polygon transformer with selectable phase displacement. When two or more ZT-Fact transformers are used on the same system, the phase displacement of the transformers can be switch selected in 15-degree increments to provide harmonic cancellation.

Soft Starter

Voltage dropping reactor designed for the starting of large motors. The SOFT STARTER incorporates a vacuum contactor and timing circuits for auto bypass of the reactor after the motor achieves full speed. The reactor has a tap switch to match the reactance to the application.
