An oil-oil bushing is disclosed which can include a rotationally symmetrical, paraboloid-like, hollow bushing element of a solid insulating material, along the axial extent of which there is formed radially toward the inside a tubular bushing channel, the wall thickness of which is tapered conically toward at least one of its two ends. An electrical bushing conductor can be fitted into the bushing channel with a form fit and protrude from it on both sides. At at least one of the two axial ends of the bushing channel there is arranged a hollow-cylindrical shielding element of a conductive material, which is thick-walled at least in certain regions, which element can enclose on one side a respective end of the bushing channel, and on another side, electrically contact a connecting conductor.
