Zusammenfassung:Results of developing and testing an experimental hybrid power transmission line with liquid hydrogen and superconducting power (SCP) cable based on magnesium diboride (MgB 2 ) are presented. Critical currents of the MgB 2 based prototype SCP cable have been determined for the first time at the forced flow of liquid hydrogen in a temperature interval of 20–26 K. Various regimes of SCP cable cryostatting with both subcooled saturated liquid hydrogen have been tested in a broad range of supply rates (7–220 g/s) and pressures (0.15–0.4 MPa).
