Abstract: A three-phase stacked triangular transformer core is provided. The transformer has three legs and six yoke parts therebetween, wherein the legs include stacked laminations. In a cross-sectional plane perpendicular to a central transformer core axis, the stacked laminations are oriented in substantially radial direction, and each leg has two leg halves, wherein each leg half has a plurality of outer corners facing a corresponding leg half of a neighboring leg. For each of the leg halves the plurality of outer corners lie on a respective straight line within a lateral tolerance, and for each leg half the straight line defined by this leg half and the straight line defined by the corresponding leg half of the neighboring leg are parallel.

Abstract: The subject of the present application is a cover for distribution transformer filled with a dielectric liquid, equipped with electronic device integrated with the cover which is applied for transmission and distribution of electric energy. The cover is characterized in that the electronic device is immersed in the dielectric liquid filling a cooling compartment fixed on the cover; the cooling compartment has side walls, a top wall and a bottom wall which bottom wall is matched in the window made in the cover and the bottom wall forms a thermal barrier between the interior of the electric power device and the interior of the cooling compartment and the both interiors of the cooling compartment and of the electric power device are hermetically closed together.
