Summary:A transformer assembly (5) with shrinkage compensation during drying or curing of the windings comprising: a core (10) having two yokes (12, 14) and two legs (16, 18), a winding (20, 22) provided about at least one of the two legs (16, 18) of the core (10), the winding (20, 22) being insulated by an insulating material (24), a metal profile (8a, 8b, 8c, 8d) per yoke (12, 14), extending in parallel to the respective yoke (12, 14) and being mounted to it, and two pistons (26a, 26b) seated in the metal profiles (8a, 8b, 8c, 8d), the pistons (26a, 26b) being movable along their axial direction which is parallel to the longitudinal axis of the at least one winding (20, 22), wherein the at least two pistons (26a, 26b) exert a force on the at least one winding (20, 22) in an axial direction of the windings (20, 22). Un ensemble transformateur (5) à compensation de retrait pendant le séchage ou le durcissement des enroulements comprend : un noyau (10) ayant deux culasses (12, 14) et deux jambes (16, 18), un enroulement (20, 22) disposé autour d'au moins l'une des deux jambes (16, 18) du noyau (10), l'enroulement (20, 22) étant isolé par un matériau isolant (24), un profilé métallique (8a, 8b, 8c, 8d) par culasse (12, 14), s'étendant parallèlement à la culasse respective (12, 14) et étant monté sur celle-ci, et deux pistons (26a, 26b) logés dans les profilés métalliques (8a, 8b, 8c, 8d), les pistons (26a, 26b) étant mobiles le long de leur direction axiale qui est parallèle à l'axe longitudinal de l'au moins un enroulement (20, 22), lesdits au moins deux pistons (26a, 26b) exerçant une force sur ledit au moins un enroulement (20, 22) dans une direction axiale des enroulements (20, 22).
