| 摘要 |
<p>The invention relates to a superconducting cable (1; 10; 30), comprising
a channel (4, 38) for a cooling liquid,
a tubular support structure (5, 37),
at least two layers (2, 3; 11-15; 31, 32, 35, 36) comprising high Tc conductors (2a, 3a) which comprise a high Tc material,
and an insulation (7, 17), in particular a tubular insulation (7),
characterized in that the conductors (3a) of the outer layer (3; 13-15; 33, 36) comprise a first high Tc material that is different from a second high Tc material of the conductors (2a) of the inner layer (2; 11-12; 32, 35), wherein the first high Tc material exhibits lower AC losses as compared the second high Tc material, and that the high Tc conductors (3a) of the outer layer (3; 13-15; 33, 36) comprise normal-conducting interruptions (41, 42, 43). The inventive superconducting cable exhibits reduced AC losses.</p> |
