Cast resin transformers

The product is suitable for use with medium voltages, power ratings up to 25/30 MVA and insulation voltage up to 36kV. The windings are made with various shapes of aluminum or copper wire.

Each manufacturing stage of the cast coils passes through automated process controls that enable a product with a uniform quality that tolerates the most severe thermal and mechanical stresses.

The use of “Step Lap” mitred cores enables losses to be significantly reduced, increases the efficiency of the transformer and guarantees low noise levels.

Impregnated transformers

This is a solution used to produce low voltage (<1.1 kV) and medium voltage (<= 24kV) coils. The windings in copper or aluminum can have different types of insulating materials, depending on the the various applications. Transformer power can reach 20MVA. The single foil technology allows the current density to be distributed over the full height of the conductor. This helps to eliminate axial stresses from short circuits and facilitates heat conduction along the axis, thus equalizing the temperature.

Coils or complete products are furthermore protected by immersion in a bath of epoxy resin inside pressurized vacuum vessels (VPI process)

Low voltage transformers and reactors

Chokes and reactors always need to be calculated, designed and built specifically for each application. There are almost no standard products in this field.

Trasfor  is able to optimally solve all operational requirements thanks to the experience of its own engineers, an extensive database of applications and specialized proprietary software used for the calculations. The choice of materials used, however, will vary depending on the ultimate purpose of the component and the type of performance and technology to be applied.

Transformers and reactors for the rail sector

The IRIS standard, the latest to regulate applications in the rail sector, sets out very strict standards for usage in this field.

This type of application is characterized by the aggressive environmental conditions, a restrictive MTBF rate (Mean Time Between Failures), the practical exclusion of maintenance and repetitive Eleqtro-mechanical stress. In addition, there is the safety aspect regarding the installation position of the units (always outside the train, on the roof or under the carriage).

A positioning that needs to satisfy the required mechanical behavior during freezing, shocks and vibration, and demands the employment of highly competent specialists and state-of-the-art Eleqtrical and mechanical simulation software to find solutions for situations that become even more complicated when complex systems with multiple transformers and reactors assembled on a single frame are involved. High-speedtrains are a good example of this.

Transformers and reactors with liquid cooling

This technical solution is particularly suitable for applications involving high currents or where space is limited. The conductor may be cooled internally with a liquid refrigerant (direct cooling) or simply placed next to dissipating surfaces where the liquid is made to circulate (indirect cooling). This type of cooling system allows heat to be dissipated away from the points of installation and has the advantage of providing compact solutions in protected enclosures, despite the high concentration of power involved.
