Quality control

Quality is never an accident, It always the result of intelligent effort.


Although computerized winding equipment is used, the uniform quality of our transformers is the result of skilled operators. Training of operators and supervisors and weekly quality review meetings are steps that we take to maintain consistent quality of workmanship between different lots. In addition, in-process inspection of each lot is performed to correct any errors during each manufacturing step. These meetings also provide the forum for suggestions and discussions of quality improvements.

Quality Policy
It is the goal of Toroid Corporation to be a world leader in quality by consistently providing products and services to the highest standards, and to continually seek ways to improve our processes and systems for the benefit of the environment, our customers, employees and other stakeholders.

Less Material
Transformer weighs about half as much as a conventional transformer with the same capacity and heat rise. The main materials used in transformers are copper and steel, both of which are getting scarcer with cost increases as a consequence. Less copper and steel usage means less mining required, less pollution from steel factories.

Smaller Size
The transformer fits into a smaller space, which allows chassis plates and enclosures to be smaller with less material used.

All of our transformers are RoHS compliant and no impregnation is needed to keep our transformers quiet so any potential environmental hazards are avoided.

Low Weight
The lower weight reduces the cost and lessens the environmental impact of freight for raw material coming into our factory, transformers sent from us to you and outgoing freight for finished product from you to the end customer.

High Efficiency Transformer designed to run cooler will only be slightly larger than a “conventionally” designed transformer and will increase the overall efficiency of the equipment, lower demand for cooling in the equipment and increase the life span of other components in the equipment.
