Abstract

Invention relates to a transformer, the core of which is not constructed with magnetic laminations. The transformer has a magnetic core (1 ) made of magnetic wires (17) wound around the coils (14, 15), which are made of copper or aluminum conductors. The coils (14, 15) can be wound in circular, oval, square shapes and so on and around these coils (14, 15), the magnetic core (1 ) is constructed not stacking laminations any longer, but winding magnetic steel wires or other alloys magnetic wires by means of appropriate winding machines, such as the toroidal winding machines. In the transformer the core (19) section is given by the cross-section area of each wire (17) multiplied by the number of turns winded around the winding (13), formed with one, two or more insulated coils which are made of electrical conductors also insulated with respect to each other.
