PURPOSE:To enhance cooling efficiency by accommodating a plurality of super-conductive strands within a hollow and stabilized enclosure, providing a cooling medium flowing path between an external housing and the stabilized enclosure with separators, and by forming to the stabilized enclosure communicating holes which connects the cooling medium flowing path at the external side and the super-conductive line side at the internal side thereof. CONSTITUTION:A plurality of super-conductive strands 11 are accommodated at the inside of hollow and stabilized enclosure 10 having a rectangular sectional view. The outside of stabilized enclosure 10 is surrounded by a hollow and cylindrical external housing 13 having a rectangular sectional view through an adequate number of spacers 12, providing cooling medium flowing path 14 between the external surface of the stabilized enclosure 10 and the internal surface of the external housing 13. Moreover, the stabilized enclosure 10 is provided with communicating holes 15 which connects the cooling medium flowing path 14 at the outside and the space at the inside thereof. Accordingly, the cooling medium flowing in the cooling medium flowing path 14 flows into the communicating holes 15 and then into the space 16 between the lines of super-conductive strands 11 at the inside of the stabilized enclosure 10. Thereby, the cooling medium is directly in contact with the super-conductive strands 11. In addition, the cooling medium also flows within the space 16 between strands of the super-conductive strands 11 at the inside of stabilized enclosure 10. |
