The Bi-2223superconducting tapes with seven filaments were fabricated to construct the superconducting cable conductor with 300 mm in length. The sizes of the cross section of the tapes are 2mm in width and 0.2mm in thickness, and the length of the tapes is 500mm. The sample fabricated by the first sintering condition of 850℃and 50h in air and the second sintering condition of 836℃and 100h in air showed the best critical current(I_C) property. The maximum I_C value was 3.8A for the tape with 500mm in length and 6.1A for the tape with 50mm in length.

为构建长度为300mm的超导电缆导体，制备了具有7根细丝的bi -2223超导带。胶带横截面尺寸宽度2mm，厚度0.2mm，胶带长度500mm。在850℃50h空气烧结和836℃100h空气烧结条件下制备的样品具有最佳的临界电流（I_C）性能。长度为500mm的胶带最大I_C值为3.8A，长度为50mm的胶带最大I_C值为6.1A。
