Guidelines and procedures for a superconducting electrical connection

Abstract

The invention relates to a conduit (100) for a superconducting electrical link, forming a unit intended to be connected at its ends for the formation of the superconducting electrical link, comprising: a cryostat (110) forming a double-walled conduit (or PiP for "pipe-in-pipe") comprising a coaxial inner tube (111) and outer tube (112) and a thermal insulator (113) occupying the annular zone between the outer tube (112) and the inner tube (111); and a superconducting cable core (105) housed inside the inner tube (111), the superconducting cable core (105) having, at room temperature, an excess length relative to the length of the cryostat (110) such that, in its superconducting state, the length of the cable core (105) is greater than or equal to the length of the cryostat (110).
