Title:
ブッシング及びこのブッシングを製造するための方法
Document Type and Number:
Japanese Patent JP2010514395
Kind Code:
A
Abstract:
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.
