摘要： A method for producing a transformer core with layers of core laminations includes forming at least one core lamination of at least two segmental laminations. An end region of a first segmental lamination has a straight crosscut edge. The straight crosscut edge of the first segmental lamination together with a corresponding straight crosscut edge of an end region of a second segmental lamination forms a form-locking straight abutting edge. The straight abutting edge is at an angle relative to the longitudinal direction of the end region of one of the segmental laminations of the first core lamination. Using core laminations having different angular orientations of the abutting edges, avoids magnetic losses such as those occurring when using conventional layering techniques. Simultaneously, an intermediate space created by conventional layering techniques between individual core lamination packs can be minimized, and thereby susceptibility to corrosion can likewise be reduced or completely avoided.

Additionally, the cooling circuit (7) is provided with a constructive arrangement configured to involve partly the core column (1.2, 1.3), that is, the constructive arrangement is configured not to form a turn around the core column (1.1, 1.3). The cooling circuit (7) is provided with cooling ducts (6), each cooling duct (6) having a cross section that partly involves a cross section of the core column (1.2, 1.3).

摘要： It is described a single-phase or three-phase distribution electric transformer, of solid insulation, for use in aerial installation, in poles, in platforms or pedestals, or installation in underground distribution network for operation in air environment, semi-submerged or submerged. Such transformer comprises at least one high voltage winding (3) and at least one low voltage winding (2) concentrically assembled around a core column (1.2,1.3), the low voltage and high voltage windings (2,3) being electrically isolated from a solid material, a core window (20) being defined as a space between two core columns (1.2,1.3), the transformer comprising at least one electrical insulation sheet (4) assembled on at least a core window (20) of said transformer, the assembly of the electrical insulation sheet (4) being defined in the longitudinal direction (300) of the transformer. Such sheet (4) avoids the formation of spiral around the core by immersion water or conductive dust. The use of this dry transformer in the underground distribution networks in the cities offers more safety to the population, because the dry transformer does not explode, apart from eliminating the risk of environmental contamination through the leakage of oil from transformers in oil. Once the dry transformer of the invention does not explode, the underground installation chambers can be simpler and more economic once they do not need to be resistant to explosion.
