Abstract
In order to get Ag-BSCCO tapes or wires with small losses, we propose a new fabrication technique named the 'wrapping method.' This is not only an alt ernative technique for fabrication of tapes and wires with very small twist pitches and well-aligned filaments instead of the conventional twisting pr ocess but also a new method of producing tapes and wires with transposed fi laments. Especially for the latter, it is theoretically confirmed that a un iform distribution of transport currents in the new two-layered multifilame ntary wire can be easily obtained by optimizing wire parameters. As a resul t transport current produced hysteresis losses can be reduced to the desire d level in the multi-layered wire with transposed filaments.
