Cast Resin transformers for renewable energy:

The three-phase transformers to photovoltaic systems are used to galvanically separate the photovoltaic system from the mains.

This particular series of transformers required low losses in order to achieve the highest possible efficiency (value determined by the rated power of the transformer). This feature is particularly important in the performance of the photovoltaic system, since a high efficiency leads to greater transfer of energy to the mains, improving the economic situation of the plant.

You can also insert an electrostatic shield between primary and secondary to reduce the noise found on the line and to achieve greater isolation between the two windings.
