The invention relates to a winding arrangement having a high electric strength. The winding arrangement has at least two juxtaposed windings (34, 37) arranged in a row, said windings being surrounded by a barrier arrangement (38, 40) configured with insulating material. A tubular electric shield (62, 63; 64, 65) is provided in the area of both front faces of the winding (5, 6; 7, 8; 58, 59; 60, 61) of at least one of said windings (1, 3, 4), said shield coaxially surrounding the corresponding winding (1, 2; 3, 4; 37) while leaving an intermediate gap (23A, 63A) and extending axially outward over the corresponding front face of the winding (5, 6; 7, 8; 58, 59; 60, 61) in such a way that its axial height (B) relative to the corresponding front face of the winding (58, 59) is the same or greater than half of the radial width (A) of the intermediate gap (23A, 63A).

L'invention concerne un ensemble enroulement de haute résistance électrique. Cet ensemble enroulement comporte au moins deux enroulements (34, 37) adjacents, disposés en une rangée et entourés chacun d'un ensemble barrière (38, 40) formé de matériau isolant. Un bouclier électrique tubulaire (62, 63; 64, 65) se trouve dans la zone de chacune des deux faces frontales d'enroulement (5, 6; 7, 8; 58, 59; 60, 61) d'au moins un des enroulements (1, 3, 4), ledit bouclier entourant coaxialement l'enroulement (1, 2; 3, 4; 37) correspondant en laissant un espace intermédiaire (23A, 63A) et s'étendant axialement vers l'extérieur, au-delà de la face frontale d'enroulement (5, 6; 7, 8; 58, 59; 60, 61) correspondante, de sorte que sa hauteur (B) axiale, relativement à la face frontale d'enroulement (5, 6; 7, 8; 58, 59; 60, 61) correspondante, est égale ou supérieure à la moitié de la largeur (A) radiale de l'espace intermédiaire (23A, 63A).
