General Transformer Corporation products

Custom ferroresonant power supply transformers provide self-regulating output voltage over a comprehensive range of input voltages including damaging spikes and sags. Ferroresonant transformers use nonlinear magnetic properties and are designed for constant output voltage and reliable power regulation.

Toroidal transformers feature a ring or donut-shaped magnetic core with one or more copper windings wound through and around the core with specialized toroid winding machinery. With their unique shape, toroidal transformers offer increased efficiency and a variety of other advantages for industrial applications. General Transformer designs and manufactures a wide range of toroidal transformers and inductors to meet your needs. Our Optimum Design practices help us work directly with you to manufacture custom transformers, and with over 45 years of design experience, we can create the best solutions for your needs. As ISO 9001-certified manufacturers, we proudly serve OEMs and manufacturers with high-quality transformers and accessories. Contact us today with any questions or to get started on your custom toroidal transformer.

Three-phase power transformers are ideal for power distribution and electrical systems requiring efficient distribution and high-power transmission capabilities. At higher power ratings, three-phase transformers are less extra-expensive, lighter, and more flexible than other power transformer configurations.

We design and manufacture inductors with toroid or laminated steel cores, multiple windings, taps, and other features as required for your specific application, per your exact specifications.

Copper wound coils are a critical component in every transformer, inductor, or choke. Transformer coil windings are used to transfer energy from a source to the load and help filter circuits.  They can also provide critical isolation for equipment from the source. While not all coils are transformers, all transformers contain one or more coils. At General Transformer Corporation, we have the expertise and industry knowledge to design and manufacture transformers and coils to meet even the strictest specifications.
