Significant progress has been made in the development of silver- sheathed BSCCO conductors for potential electric power and high-field magnet applications. High critical current density (J{sub c}) has been achieved in mono- and multifilament conductors fabricated by the powder-in-tube technique; J{sub c} up to 12,000 A/cm{sup 2} has been observed at 77 K, in an 1260-m-long multifilament conductor. A high- {Tc} magnet generated a self-field of {approx} 3.2 T at 4.2 K. A 0.25 KVA high-{Tc} transformer has been developed with the use of a racetrack-wound solenoid. Strain tolerance of the conductors was evaluated by in-situ tensile and bending tests. Tensile testing indicated that multifilament conductors have better strain tolerance than monofilament conductors and are able to retain 90% of their initial current (I{sub c}) at a strain of {ge}1%. Effect of superconducting/Ag ratio on bending characteristics of the conductors was also evaluated; preliminary results indicate that the irreversible strain limit of the monofilament conductor increases with decreasing superconductor/Ag ratio.
