Abstract:
1. An electric power transport system comprising: at least a cold dielectric superconducting cable including two concentric phases of superconducting material electrically isolated one from the other by a dielectric and a first cryogenic fluid flowing channel inside the cable; a cryostat circumscribing a cryogenic fluid flowing channel, said channel containing said cable; and a cryogenic fluid, said cryostat comprising at least two modules, each comprising an inner tube, having at least a coupling flange for said at least two modules extending in a radially external direction; and an outer tube having a length not greater than the length of said inner tube; wherein at least one of said modules comprises at least a radially inner gasket and at least a radially outer gasket on the coupling surface of said at least one flange, the radially external perimeter of the inner gasket being spaced from the radially internal perimeter of the outer gasket; and at least a duct having a first end connected to said coupling surface of said at least one flange comprised between said gaskets and a second end connected to the environment external to the cryostat.
