Abstract :
Recent progresses in Bi2212 wires have proved its suitability for round wire developments and high field magnet insert manufacturing. In order to prepare cabling developments the Commissariat a l´Energie Atomique at Saclay has developed in collaboration with the Nexans Company a Bi2212 wire having 18 sub-elements. The results of the critical current measurement are presented here and compared with already existing ribbons. The round wire has also been twisted to study twisting degradation.
