The Technology of Fabrication & Application of Bi-2223 HTS Wires at InnoST

Comparing with the ordinary conducting wires, HTS wires have primary advantages of low loss and high current carrying capacity (as much as 100 times more than that of ordinary conducting wires). HTS wires, as a new type material, now are being widely applied to a great variety of areas. The R&D and fabrication of the Bi-2223 HTS wires at Innova Superconductor Technology Co., Ltd (InnoST) are introduced, including the main research results of cutting down the manufacture cost, improving the performance of the HTS wires and developing the diversified HTS wires. Meanwhile some HTS magnets and HTS current leads that we have produced over the past few years are introduced, such as 1.5 T Ag-sheathed Bi-2223 magnet and 15 kA HTS current lead, which is used in TOKAMAK system, and so on. The welding joint resistance of Bi-2223 wire is also studied.
