Summary: | A cooling structure for an energized conductor of a three-phase coaxial superconducting cable, and the energized conductor of the superconducting cable. The cooling structure comprises: a low-temperature Dewar tube (1), which is a hollow cylindrical structure; and an energized conductor (2) provided in the low-temperature Dewar tube (1), the energized conductor (2) being a hollow cylindrical structure, on which a flexible framework (21), a first insulating layer (22), an A-phase superconducting layer (23), a second insulating layer (24), a B-phase superconducting layer (25), a third insulating layer (26), a C-phase superconducting layer (27), a shielding layer (29), a fifth insulating layer (210), and a protection layer (211) are wound in sequence from inside to outside. A hollow portion of the flexible framework (21) constitutes a first liquid nitrogen channel (11); a gap between the inner wall surface of the low-temperature Dewar tube (1) and the outer wall surface of the protection layer (211) constitutes |
