A superconductor manufacturing process provides electrical insulation and enhanced transverse electrical resistivity of multifilament superconductor strands based on Nb3Sn. The process includes forming, during the early manufacturing steps in which the product is relatively short and of large cross section, resistive barriers around bundles of filaments in an oxide powder doped with conductive materials. In subsequent steps, an electrically insulative powder is used to insulate between a copper tube surrounding the bundles of filaments and an outer resistive ring or to insulate around multifilament strands. |
