    • A bushing is disclosed with a duct for accommodating a conductor which is surrounded by an electrical field grading insulation. The bushing includes a core with a shell encapsulating the grading insulation and a flange surrounding the shell and carrying through holes distributed over its circumference for allowing the bushing to be attached to a wall. The shell and the flange can be in one piece and include an insulating matrix material. The through holes can be surrounded by metal inserts each forming an annular surface flush with a surface of the flange. A test tap can include a contact pin which is electrically conductively connected to an outermost layer of the grading insulation and surrounded by a contact ring connected to every second metal insert by connection wires for grounding the contact pin via the contact ring when the test tap is not in use and covered. The core can be produced by filling a mold with the liquid matrix material after components of the grading insulation and other parts have been fixed in the liquid matrix material.
    • 公开了一种用于容纳由电场分级绝缘体包围的导体的导管的衬套。 衬套包括具有封装分级绝缘体的外壳和围绕壳体的凸缘并且承载分布在其圆周上的孔的芯,以允许衬套附接到壁。 壳体和凸缘可以是一体的并且包括绝缘基体材料。 通孔可以被金属嵌件包围,每个金属嵌件形成与凸缘的表面齐平的环形表面。 测试分接头可以包括一个接触针,该接触针导电地连接到分级绝缘体的最外层,并且被连接到每个第二金属插入件的接触环围绕,所述接触环通过接线用于通过接触环使接触针接地, 不使用和覆盖。 核心可以通过在分级绝缘件和其他部件的部件已经固定在液体基质材料中之后用液体基质材料填充模具来生产。
