PURPOSE:To provide a superconductive conductor having a small pressure loss, and good cooling characteristics and superconductive stability. CONSTITUTION:Superconductive wires 1 and cooling tubes 3 are twisted with each other and put in an outer tube 5, and cooling medium passages 6 for sending cooling medium are formed in the spaces between the superconductive wires and inside the cooling tubes. A CuNi material is used for the cooling tubes. While heat transmission distances between the superconductive wires and the cooling tubes are thus kept uniform, the superconductive wires are cooled by indirect cooling and direct cooling. |
