A transformer includes: —a plurality of windings (P, S1, S2) wound on a coil former (100), preferably in the form of a one-piece coil former, —a pair of first insulating flanges (106) separating a first winding (P) from a pair of second windings (S1, S2), —a pair of second insulating flanges (104) defining together with the first insulating flanges (106) two winding spaces for the second windings (S1, S2). The ends (P1, P2) of the wire of the first winding (P) extend across the winding spaces for the second windings (S1, S2). Insulating walls (208) are provided extending between the ends (P1, P2) of the wire of the first winding (P) and the second windings (S1, S2) to provide insulation therebetween.
