Validation of the superconducting and insulating components of a high-power HVDC cable

Across the European continent, the integration of increasing numbers of renewable energy sources within the electricity grids has become a strategic objective, requiring the modernization and expansion of the grids. In particular, recent studies have emphasized the major role of bulk power lines with lengths of several hundred kilometers. These pan-European transmission corridors with capacities of 5 to 20 GW were shown to be necessary, no matter which energy scenario is explored [1], [2].
