FIELD: electricity. ^ SUBSTANCE: invention proposes superconducting cable, simple in formation of twisted structure even when multiple cable conductors are used, and system of DC transfer comprising such superconducting cable. Superconducting cable (1) has structure formed by joint twisting of two types of cable conductors (two first conductors (2) and one second conductor (3), having various structures and their further placement into heat insulation tube (7). Each first conductor (2) has the first superconducting layer (2a) used either as outgoing line or for transfer for pole in process of DC transfer, and does not have a superconductive layer that varies from the first superconductive layer (2a). The second conductor (3) has the second superconducting layer (3a) used either as reverse line or neutral line in process of DC transfer, and does not have a superconductive layer that varies from the second superconductive layer (3a). The second superconductive layer (3a) has internal diametre that exceeds external diametre of the first superconductive layer (2a). ^ EFFECT: simplified manufacturing of cable suitable for DC transfer. ^ 21 cl, 9 dwg, 6 ex |
