Zusammenfassung:The present application relates to a bushing connection shielding system (80), a turret assembly with the bushing connection shielding system and a slip-free mounting device for mounting the bushing connection shielding system within the turret assembly of a high voltage transformer. The bushing connection shielding system comprising a shielding tube (1) with an equalizing ball (6) at an upper end of the shielding tube (1), said equalizing ball (6) being configured to electrically shield a lower end (5) of a connected high voltage bushing. The shielding tube (1) is covered by paper (2) and an electrical shield formed by a dielectric barrier which comprises at least one barrier layer (3) is provided to the equalizing ball (6). A seamless interface between the paper (2) and the at least one dielectric barrier layer (3) is provided in that at least a lower end (32) of the dielectric barrier layer (3) is integrated in the paper (2).
