Electrical feedthrough for superconducting element

摘要

The bushing has a central electrical conductor (19) surrounded by an electrically insulating sheath (20). An electrically conducting screen (21) is connected to the ground potential. The screen encloses the sheath on a section extending from a part of an intermediate enclosure (12), of a superconducting cable connection structure, in contact with a cryogenic temperature enclosure (11) of the structure until a support clamp (14) between the enclosure (12) and an ambient temperature enclosure (15) of the structure. The enclosure (15) is filled with an insulator liquid e.g. silicone oil.
