A newly designed Bi2223 tape incorporating an Ag alloy wire in superconducting core is described. It is shown that the new structure considerably improves the superconducting properties of monofilament tapes. The maximum Ic is as high as 75 A, and Jc= 1.6104A/cm2 , increases of 30% over those of conventional superconductor tape. At the same time the mechanical properties of the new Bi2223 tape show considerable improvement.
