In an electrical system, the transformer helps regulate voltage and current. Although primary and secondary winding coils are separated, they are magnetically connected through a common core. Both coils have to function properly for the transformer to operate efficiently.

Toroidal Winding

You can reduce loss of power flow in your electric machinery with a toroidal transformer. We will custom make these transformers for your specific needs and optimize them with toroidal winding from size 40 wire to 10 gauge wire.

To improve the overall operation of your transformers, we do rewinding according to your request. Services also include quick order turnarounds based on your needs concerning lead time. With our 1-year guarantee, we provide you with peace of mind about your new or rewound transformers.
