Background

The cable core structure of the superconducting cable mainly comprises a support body, a conductor layer, an insulating layer, a shielding layer, a copper layer, a fastening layer and the like. The conductor layer is mostly in a narrow-band shape, and the cabling process is wound on the support body in a multi-band stranded wire mode; the shielding layer and the copper layer may be in a wide band shape or a narrow band shape, and in the case of the narrow band shape, the cabling process of both is the same as that of the conductor layer.

The cable forming process of the superconducting cable is layered winding, and the specific process is as follows: firstly, a certain amount of non-woven fabric or PPLP (polypropylene laminated paper) is wound on a support body to be used as a buffer layer, then 2 layers of carbon paper are wound to be used as a semi-insulating layer, then 1 layer of superconducting tape is wound, 2 layers of carbon paper are wound, then PPLP insulating paper is wound according to a forward or reverse process in multiple layers, and winding of other layers is completed.

At present, for winding of a conductor layer or a shielding layer, when a superconducting tape is paid out by a tape reel according to a certain tension, the superconducting tape enters a wire collecting device after passing through a wire guide wheel, is twisted to a central support body, is formed by a pressing die, and is immediately wrapped and bundled by carbon paper or non-woven fabric to complete the winding of the conductor layer.

Although the superconducting tapes are guided and collected by the line concentration device, no actual die forming is available for the arrangement condition of the tapes in the winding process, and no effective avoidance measures are available when the tapes are not uniform, so that after the cable is wound, when a conductor layer or a shielding layer is inspected, the conditions of overlapping, dislocation and stressed folds are often found, and the adverse results of the reduction of the electrical performance of the superconducting tapes or the disappearance of the superconductivity and the like are caused.

In order to solve the above problems, the present invention is directed to a superconducting cable tape dispenser.
