This White Paper presents some recent developments in superconductivity and explains how Nexans is serving this market.
It opens with the blackout question, and explains how high temperature superconductors (HTS) can contribute to the resolution of this problem. Secondly, it describes HTS cable architectures and explains the effects of superconductor cables on power grid flows. Thirdly, it presents some current case studies and relates other Nexans superconductor developments, concluding with economic, financial and environment benefits. Finally, it explains policy implications of superconductor cables.
