1. a device, it has at least one superconducting cable and around first cryostat for delivery of the first cooling agent of described cable, described the first cryostat is coaxial and each interval by two, the metal tube that is surrounded by betwixt heat insulation layer forms, and described the first cryostat surrounds out a cavity in its whole length, described cable is set in described cavity and by described cavity, when described device moves, carries the first cooling agent, wherein, serviceability temperature is cooled to 39K or lower, the cooling agent of liquid state or gaseous state is as the first cooling agent, and wherein, around described the first cryostat (K1), coaxially and be with it formed with the second cryostat (K2) for delivery of the second cooling agent in compartment of terrain, what described the second cryostat (K2) was coaxial by two equally and each interval is settled, be surrounded by the metal tube (13 of heat insulation layer (15) therebetween, 14) form, and be 112K or lower liquid gas by described the second cryostat (K2) delivery temperature when described device moves, it is characterized in that,-use magnesium diboride as the material of superconductivity, andIn-gap (12) between described the first cryostat (K1) and described the second cryostat (K2), be mounted with high voltage bearing insulant (16), described insulant (16) surrounds the outboard tube (10) of described the first cryostat (K1) and covers on it, and when described device operation, described insulant (16) is passed the liquid gas of described gap (12) conveying around washing away and being soaked into by it.
