Toroidal transformers

Design and manufacturing of toroidal transformers for industrial applications

Available features and configurations

Toroidal transformers have the advantage over laminated transformers, whether single-phase or three-phase, of ensuring high efficiency with significantly reduced size and weight. They are used in all electrical devices that require minimal space.

reduced and at the same time high performance (e.g. transformers for audio use and/or transformers for electromedical equipment).

Toroidal transformers must in fact transfer full power to the load, without introducing limitations that would necessarily lead to a decrease in the performance of the finished product on which these transformers are installed.

toroidal transformersSVTThey guarantee excellent performance and the greatest flexibility in terms of dimensions as the magnetic cores are cut based on the specific requests of the end customer.

Both single-phase and three-phase transformers are made, and the toroids are supplied complete with a fixing kit consisting of

from an iron disc and two rubber ones, kit necessary for the assembly of the toroidal transformer itself.

Toroidal transformersSVTthey can be supplied complete with accessories and customized wiring

based on the specific needs of the end customer.

Transformers for every need

Toroidal transformersSVTThey are designed and manufactured with top quality materials, electrolytic copper wire and aluminum conductors, insulators with high dielectric and thermal properties (classes F and H), impregnated with paint or epoxy resins, and are extremely robust and safe, suitable for any installation requirement.

Toroidal transformersSVTThey can also be supplied complete with epoxy resin in the central hole, on which suitable inserts and/or supports are applied for fixing the transformers themselves, or the transformers can be placed inside a plastic box, which guarantees the transformers themselves a higher IP protection level for applications that require it.

A protective screen can also be applied between the primary and secondary windings to ensure greater insulation. Upon request, a thermal cutout can be applied to the primary winding to protect against overheating. This thermal cutout can be either automatic or manual reset, depending on the application. The quality of toroidal transformersSVTIt is checked on multiple levels: each production phase is controlled, from the initial winding to the final testing of the transformer itself.

Tested product

Each transformer undergoes 100% testing after completion of production. This ensures that each transformer's electromagnetic performance and guaranteed safety level are certified. Pre-testing and final testing are performed in compliance with current regulations.CEI EN 61558 – CEI 96.7 – 96.8 – CEapplicable, depending on the type of transformer and its use. Careful control of production processes and customization of testing with dedicated and specifically designed equipment guarantees electrical transformersSVTmaximum reliability. It should also be noted that toroidal transformersSVTThey are made with automatic machines in order to guarantee maximum reliability and repeatability in the electrical tolerance parameters.SVTdesigns and develops various types of toroidal transformers, designed and customized to meet the end customer's needs, maximizing performance and preventing any type of problem.


Toroidal transformersSVTthey can also be made with extra-flat lamellar cores which allow for further reductions in the weight and size of the transformers themselves while maintaining the same power output.

Toroidal transformersSVTThey cover a wide range of applications with dimensional and technical characteristics ranging from standard to the most complex customizations.


SVTsupports its customers from the design and customization of toroidal electrical transformers, ensuring maximum results in terms of cost and technical performance.SVTThey are used in various sectors, such as control panels, home automation, and more generally in all applications requiring a voltage variation compared to the voltage supplying the transformer itself. Precise and stringent testing ensures a high level of safety and reliability for each transformer produced, in compliance with current national and international regulations.
