Abstract :
Recent progresses in Bi2212 wires have proved its suitability for round wire developments and high field magnet development. High energy storage magnets can be foreseen leading to cable developments. In order to prepare such work CEA Saclay has developed in collaboration with the Nexans company a Bi 2212 wire having 18 sub-elements. The round wire has been twisted to study losses and twisting degradation. The results are presented here and compared to losses measurements made on already existing ribbons.
