Abstract
An exemplary plug-in high-voltage bushing connects an electrical conductor to a metal-encapsulated component, which is filled with insulating agent, of a high-voltage installation. The bushing is rotationally symmetrical with respect to an axis and has a centrally routed electrical conductor, a field control device and an insulator surrounds the electrical conductor. The bushing also includes a tapering section that dielectrically strengthens a joint after insertion of the bushing into a plug part, which forms a seal for the insulating agent. The joint is arranged between an insulating sleeve of the plug part and the tapering section of the insulator. The bushing has capacitor plates, which are electrically isolated from one another by an insulating film, are integrated into the insulator, and pass through the mounting flange into the tapering section of the insulator.
