| Zusammenfassung: | A bushing (1) for electrical current and/or voltage through a grounded plane (2) comprising a substantially rotationally symmetrical insulating body (3) surrounding a central electrical conductor (4). The bushing exhibits a sealing member (5) for gas /liquid sealing between the conductor and the insulator body, which is in the form of a so-called RIP (Resin Impregnated Paper) body. According to the invention, the bushing is provided with a compressible sealing element (6), which forms a gas /liquid seal, integrated with the insulating body, between the conductor and the insulating body. The invention also relates to a method of manufacturing a bushing. The bushing is preferably intended for higher voltages, from 36 kV up to 800 kv and above. The bushing may preferably be used with a transformer but also with a cable termination. |
