    摘要: It is presented a bushing (1) comprising a condenser core (3) arranged to house an electrical conductor (15) along a central axis (X) of the condenser core (3), wherein the condenser core (3) has a tapering end portion (3-2a) arranged to be in contact with a fluid dielectric having higher dielectric withstand strength than air, the tapering end portion (3-2a) presenting a surface having a first portion (4-1) with a first inclination (I-1) in the axial direction and a second portion (4-2) with a second inclination (I-2) in the axial direction, which second inclination (I-2) differs from the first inclination (I-1), wherein the first portion (4-1) and the second portion (4-2) define planes that intersect the central axis (X). A system comprising such a bushing is also presented herein.
