Feedthrough i.e. vacuum-tight feedthrough, for e.g. flywheel energy storage, has connecting part accommodated in inner bore hole and including radial flange part that forms stage on mantle surface, where inner bore hole forms another stage

摘要

The feedthrough has a rotatable symmetrical insulation body (4) formed with an inner bore hole (5). An electrically conductive connecting part (6) is accommodated in the inner bore hole, and includes a radial flange part (1) that forms a stage (16) on a mantle surface (17). The inner bore hole forms another stage (19), and the flange part is provided with a mounting stage on which a fixing ring is defined. An electrical insulation hose (12) is arranged in a section (11) of the inner bore hole between the connecting part and an inner wall of the inner bore hole. The insulation body is made of plastic or ceramic material. An independent claim is also included for an evacuated housing.
