    摘要: An exemplary high-voltage outdoor bushing is disclosed which includes a conductor extended along an axis, a condenser core and an electrically insulating polymeric weather protection housing molded on the condenser core. The condenser core can contain an electrically insulating tape which is wound in spiral form around the conductor. Capacitance grading insertions can be arranged between successive windings of the tape. A cured polymeric insulating matrix embeds the wound tape and the capacitive grading insertions. A moisture diffusion barrier can be incorporated inside the condenser core prior to molding the weather protection housing.

    摘要: 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 mould with the liquid matrix material after components of the grading insulation and other parts have been fixed in the liquid matrix material.
