Custom Power Transformers

At General Transformer, there are no off-the-shelf transformers. Our USA-made products are custom engineered and manufactured to match your design needs. We build:

    • Laminated steel isolation transformers with ratings from 100VA to 60 kVA for 50/60 Hz operation
    • Autotransformers to 120 kVA
    • Transformers for 400 Hz operation to 20 kVA or more
    • And other configurations or capabilities

Whether you need a specific temperature rating, size, or mounting configuration, we work closely with you to create transformers with the proper magnetic topology for your application. Contact us today to learn more about how custom power transformers from GTC can enhance your OEM facility, manufacturing operation, or other industrial jobs.

Types of Custom Power Transformers

Whether you have a small or large project, we are dedicated to meeting each of your specifications. Available ratings and transformer capabilities depend on several factors. Before beginning your order, always consider the following aspects:

  • Power requirements
  • Maximum voltages
  • Currents
  • Frequency

We design and manufacture both single and three-phase transformers with toroid or laminated steel cores, with multiple windings, taps, and other features as required. If you are unsure which specifications or configurations are best for your planned use, call 972-442-1285 to speak with an expert.

Ferroresonant Transformers

General Transformer is one of the leading producers of constant voltage ferroresonant transformers and other ferroresonant designs. These custom power solutions provide reliable regulation and feature rugged constructions to withstand harsh environmental conditions. They protect sensitive loads from noise, surges, and other disturbances.

Toroidal Transformers

Custom toroidal power transformers are designed for compact applications, providing high efficiency in a small and lightweight package. They feature a ring-shaped magnetic core to provide lower losses, reduced operational noise, and single bolt mounting.

Three-Phase Transformers

For higher power ratings, we design and manufacture custom three-phase transformers. Three-phase transformers are a cost-effective, high-quality option for industrial applications due to their lightweight constructions and flexible performances.


Industrial Applications for Custom Transformers

Custom-manufactured power transformers from GTC are engineered to provide efficient and reliable operations for any industrial application. Examples include:
