Three types of Ag sheathed (Bi, Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x} tapes were developed: single core tape, multifilamentary one and Ag alloy sheathed one. Single core tape showed high Jc of 16,000 A/cm{sup 2} at 77 K, 0T. This was achieved by the increasing of density of the oxide core. High density of the oxide core resulted in highly oriented, less second phase contained microstructure. 6 to 8,100 multifilamentary wires were successfully fabricated and showed better bending strain tolerance. AgMg alloy sheath instead of pure silver sheath increased 0.2% proof stress to 10 MPa with Jc of 10,000 A/cm{sup 2} at 77K, 0T.
