The invention belongs to the technical field of cables, and provides a cable and a cable preparation method. The cable comprises a cable core, a buffer water-blocking layer, a smooth aluminum sleeve, an isolation layer, a flexible conducting layer and an outer sheath which are sequentially stacked from inside to outside in the radial direction of the cable, the cable core is used for transmitting electric energy, the buffer water-blocking layer is used for blocking water, the smooth aluminum sleeve is used for bearing a part of short-circuit current, the isolation layer is used for insulating the smooth aluminum sleeve and the flexible conducting layer, and the outer sheath is used for protecting the flexible conducting layer. The flexible conducting layer comprises a plurality of flexible conducting wires, the plurality of flexible conducting wires are arranged at intervals along the circumferential direction of the cable, the plurality of flexible conducting wires are used for bearing the other part of shor
