Abstract: Cooling arrangements for non-liquid immerged transformers are disclosed. In an aspect, a non-liquid immersed transformer comprises a magnetic core having a winding axis and at least two coil windings wound around the magnetic core along the winding axis. Cooling tubes made of dielectric material are arranged inside of at least one of the coil windings to cool down the coil winding using dielectric fluid flowing through the dielectric cooling tubes.

Abstract: Insulating modules for transformers are disclosed. Example insulating modules comprise dielectric screens and supporting blocks. The supporting blocks support the dielectric screens over windings of the transformer. The dielectric screens have first substantially even portions configured to adapt in spaces defined by corresponding cylindrical barriers arranged between first and second windings of the transformers and second substantially even portions, transversal to the first portions and to the first windings of the transformers and extending outwards from the first portions and beyond the supporting blocks.
