Summary

A NIOBIUM-TIN COMPOSITE CONDUCTOR HAS BEEN MANUFACTURED. ALTERNATING CURRENT LOSSES WERE GREATLY REDUCED BY THE USE OF A FINE FILAMENT SIZE, A TIGHT TWIST PITCH AND A SMALL WIRE DIAMETER WITH A BRONZE MATRIX. A TRIPLEX CONDUCTOR WAS CONSTRUCTED BY CABLING 3 STRANDS AT A TWISTING PITCH OF 3 MM, AND A SMALL COIL WAS WOUND FROM THIS CABLE. WITH DIRECT CURRENT THE COIL GENERATED A FIELD OF 1.3 T AT THE CRITICAL CURN. PRELIMINARY STUDIES HAVESHOWN THAT, IF THIS CONDUCTOR IS USED IN SUPERCONDUCTING ARMATURE WINDINGS OF ROTATING MACHINES, ECONOMICAL BENEFITS ARE OBTAINED COMPARED WITH THE USE OF CONVENTIONAL ARMATURES.
