Abstract

A conduit for the transport of cryogenic media, in particular a superconducting cable, includes at least two metal pipes arranged concentrically and spaced apart from one another, an insulation layer being situated in the annular gap between the metal pipes and the annular gap being evacuated. The exterior of the metal pipe (4) is separated at predetermined intervals and above each opening a pump connector (10) is welded vacuum-tight to the outer metal pipe (4).
