Production

Fdueg has always focussed on customers’ requirements and, in the long run, we have come to realize that our trump card has been our ability to customize products to meet customers’ needs: Fdueg has always built up close relationships with customers in order to offer and guarantee the best possible product, service and solution.

By targeting the sector of special/particular solutions, Fdueg has risen above its main competitions in the electrotechnical field: our high competence in design and manufacture has allowed us to study and make lots of unique items perfectly meeting customers’ needs. The fact that such products are not often mass-produced underlines that, the product itself, which can be seen as a prototype, must meet certain requirements from the very beginning, and here again Fdueg has always been able to do the best. Fdueg has developed its own design software and it also makes use of solution systems for finished components in order to validate calculations and projects. The application fields in which the most particular fittings have been developed are: offshore applications, test labs, alternative energy production, conversion and rectification, metallizing and plating plants.

Industry applications - UPS

Products belonging to continuity groups usually work at low voltage. Transformers and reactors are dimensioned keeping into account customers’ special needs to obtain the modulation of output current which is the most suitable for the circuit in which UPS have to be fitted. An efficient design solutions is to build the transformer and reactance as a single component, thus decreasing weight and size. Generally speaking, excellent performance and top-quality standards are required.

Industry applications

In induction furnaces the fusion of the material is obtained by joule effect, due to the induced current that runs through a conductor immersed in a varying electric field generated by one more windings carrying current. The features of such plants are extremely variable depending on their work load, capacity, cooling system and presence or absence of a core; in this field Fdueg has developed special expertise in the design of smoothing reactance, where high currents and the insertion of tapping to control the inductive value are extremely important. Each application needs to be customized to meet the customer’s needs.

Renewable energy

In new concept plants (solar, wind), transformers and reactors are mainly used for AC/DC conversion. The components of these applications must be developed with a view to their discontinuous working with variable parameters. In order not to compromise the performance of the plant, it is essential to ensure optimum efficiency, assessing in a reliable way losses in operating and non-operating conditions. In most cases transformers are protected by an enclosure protection box designed to meet customers’ needs.
