The invention relates to an oil-oii bushing (70), comprising a rotationally symmetrical (14), paraboloid-like, hollow bushing element (12, 72) of a solid insulating material, along the axial extent of which there is formed radially toward the inside a tubular bushing channel (16), the wall thickness of which is tapered conically toward at least one of its two ends, and also an electrical bushing conductor (18, 76) fitted into the bushing channel (16) with a form fit and protruding from it on both sides. At at least one of the two axial ends of the bushing channel (16) there is arranged a respective hollow-cylindrical shielding element (30, 52, 80, 82) of a conductive material, which is thick-walied (44) at least in certain regions, which element encloses on its one side the respective end of the bushing channel (16) and the bushing conductor (18, 76) protruding from it and on its other side, respectively, is intended for receiving and electrically contacting a respective connecting conductor (74, 78), the axial ends of the shielding element (30, 52, 80, 82) being of a round design. The invention also relates to an oi! transformer with an oil-oil bushing (70) according to the invention.
