Abstract
An electrical transformer comprises a core structure formed from magnetizable material and comprising a first annular element in the peripheral surface of which is formed at least a pair of helical slots. The core structure includes a second element which closes the open ends of the slots and located in each slot is at least two windings forming the primary and secondary windings of the transformer. Each winding extends along one slot and returns along the adjacent slot.
