METALLIC CURRENT LEAD FOR CRYOGENIC SYSTEM

摘要

Metallic current lead for cryogenic system comprising a conductor, a first end of which is intended to be connected to an electric supply cable (10) located in a first medium (11) at ambient temperature and a second end of which is intended to be connected to a user device (14) located in a second medium (15) at 77 K, characterised in that the said conductor has the shape of a metal rod (1), the lateral wall of which is thermally insulated and the end faces (12, 13) of which are respectively secured to two metal heat-exchangers (2, 8) one immersed in the said first medium and the other in the said second medium.
