    Abstract: The present invention refers to the method for manufacturing a stacked triangular core transformer. The method is used in a production of distribution and power transformers using a stacked technology for core transformers. The method comprises a step of assembling a triangular core (1) which is comprising the following steps: a) positioning of two halves of one leg (2a) on the assembly stand on the horizontal position; b) securing the positioned halves using an upper part of adapters (16b) on the assembly stand; c) positioning of an outer clamping beam (6) underneath two leg halves (2a) at the one end of the leg halves (2a); d) assembling the yoke segment (3) at the one end of two halves (2a) of the core leg (2); e) forming a first clamp of the frame (5); f) forming a second clamp of the frame (5) at the other end of the two halves (2a) of the core leg (2) by repeating the steps "c" to "e"; g) tightening the first clamp and the second clamp together by securing means; h) rotating a single core frame (5) into vertical position and releasing securing bar (17) of the assembly stand; i) assembling two additional single core frames (5), by repeating steps "a" - "h"; j) positioning the all three single core frames (5) in abutting position, and then tightening them mechanically at the bottom and the top of the frames.

    Abstract: A preferred embodiment of a three-phase transformer (100) includes a first (104), a second (106), and a third winding leg (108), and a first, a second, and a third winding positioned around the respective first, second, and third winding legs. The first, second, and third windings (10) each includes an electrical conductor (16) wound into a plurality of overlapping layers each formed by a plurality of adjacent turns of the electrical conductor, and an insulating material (18) without end fill positioned between each of the overlapping layers. The electrical conductor has a transition portion formed therein between a first and a second of the overlapping layers. The transition portion is at least one of bent to form an offset in the electrical conductor, and secured to at least one of the plurality of adjacent turns.
