Abstract: 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.

Abstract: An oil-filled transformer switching frame is disclosed which includes at least one longitudinal channel element that is essentially formed by a wall that is curved in a U-shaped manner, for receiving in its inner region stranded conductors of an oil tank of an oil transformer. The wall of the channel element can include a first layer of mechanically strong, planar insulating material and a second layer of mechanically strong, planar insulating material that is adjacent to and fundamentally parallel to said first layer, the first layer and the second layer being connected to and spaced apart by a third layer of a mechanically strong, corrugated insulating material having hollow spaces that can be flooded with a fluid by way of lateral edges.
