ABSTRACT:
The transformer comprises a magnetic circuit (8) as well as, in the case of each phase, a high-voltage electric circuit (17) and a low-voltage electric circuit (18) both wound around at least one section of the magnetic circuit (8). The electric circuits (17, 18) are arranged in at least one electrically insulating annular coil form (11) which, under service conditions, is interposed between the electric circuits (17, 18) and the aforementioned section of the magnetic circuit (8). Utilization in particular is for improving the occupation of electric windows by the magnetic circuit and of magnetic windows by the electric circuit.
