Abstract

1. Electric transformer comprising a magnetic frame (1) comprising at least one yoke (3, 4) and at least one core (2) which define together at least one substantially rectangular window (6), at least one high-voltage electric circuit (13) and at least one low-voltage electric circuit (11) arranged round an insulating tube (9) which in turn surrounds the magnetic core (2) which is assigned thereto, characterized in that each end of the insulating tube (9) projects axially beyond the electric circuits (11, 13) which it supports and is associated with an annular spacer (28, 29) interposed between the annular extremity of the electric circuits (11, 13) and the yoke (3, 4) and that this spacer (28, 29) is provided on that face which is directed towards the core (2) with two radially displaced bearing surfaces, one surface (34) being applied against the magnetic core (2), the other surface (37) being closer to the windings (11 to 13) and applied against the insulating tube (9).
