Zusammenfassung:	Long high critical current density Bi-2223/Ag tapes are required for the realization of cables and windings to be integrated in electric power devices. A cooperation agreement among CISE SpA, Europa Metalli and INFN, concerns the development of silver-sheathed multifilamentary Bi-2223/Ag tapes, over 100 meters long, produced by means of the Powder-In-Tube (PIT) technique. The Bi-2223/Ag tapes were thermomechanically processed and then wound into double pancakes by the React and Wind method. This article presents and discusses the electrical and magnetic characterization of the tapes, their degradation after winding as well as the performances of the pancakes tested after the final assembling.
