Abstract: A variable-structure stacked cable topology includes: a plurality of sections of stacked cables. The plurality of sections of the stacked cables are connected sequentially. The sections of the stacked cables includes a plurality of base tapes at an equal quantity. The plurality of base tapes are connected mutually. At least one of the plurality of base tapes is a superconducting tape. A cable topological structure is formed by sequentially connecting a plurality of sections of stacked cables. Each of the sections of the stacked cables is provided with superconducting tapes or a combination of superconducting tapes and copper tapes to form a variable-structure cable topological structure. By packaging a different number of superconducting tapes in each area, this section of cable can be twisted into a coil in such a way that a critical current of the whole coil can be approximately uniform along a length direction of the cable.
