SUPERCONDUCTING CABLE |
摘要 |
Superconducting cable (1) comprising: a) a layer (20) of tapes comprising superconducting material; b) a tubular element (6) for supporting said layer (20) of tapes comprising superconducting material; c) a cooling circuit, adapted to cool the superconducting material to a working temperature not higher than its critical temperature; characterized in that said tubular element (6) is composite and comprises a predetermined amount of a first material having a first thermal expansion coefficient and a second material having a thermal expansion coefficient higher than that of said first material, said thermal expansion coefficients and said amounts of said first and second material being predetermined in such a way that said tubular element has an overall thermal shrinkage between the room temperature and said working temperature of the cable such as to cause a deformation of said tapes comprising superconducting material lower than the critical deformation of the same tapes. |
