HIGH-TEMPERATURE SUPERCONDUCTING WIRES WITH HIGH STRUCTURAL DENSITY OF CURRENT Russian patent published in 2020 - IPC H01L39/14 

FIELD: electricity.

SUBSTANCE: invention can be used for creation of high-temperature wire with increased design density of current. Summary of invention is that laminated superconducting composite wire comprises: first layer of high-temperature superconductor having first surface and second surface opposite first surface; a first electrically conductive coating layer which is superimposed on the first surface of the first layer of the high temperature superconductor and is in direct physical contact therewith; a second electrically conductive coating layer which is superimposed on the second surface of the first layer of the high temperature superconductor and is in direct physical contact therewith; a first lamination layer which is superposed on the first electrically conductive layer and is attached thereto; a stabilizer layer with a first surface and a second surface opposite to the first surface, wherein the first surface of the stabilizer layer is applied onto the second electrically conductive coating layer and is attached thereto; a second layer of the high-temperature superconductor having a first surface and a second surface opposite the first surface; a third electrically conductive coating layer which is superimposed on the first surface of the second layer of the high-temperature superconductor and is in direct physical contact therewith; a fourth electrically conductive coating layer which is superimposed on the second surface of the second layer of the high-temperature superconductor and is in direct physical contact therewith; a second lamination layer which is superimposed on the fourth electrically conductive layer and is attached thereto; wherein second surface of stabilizer layer is superimposed on third electrically conductive coating layer and is attached thereto; and wherein a first fillet located along the first edge of the laminated superconducting collecting wire and connected to the first lamination layer and the second lamination layer, and second fillet located along second edge of laminated superconductive collecting wire and connected to first lamination layer and second layer of lamination.

EFFECT: technical result is enabling creation of high-temperature superconductors with high design density of current.
