SUPERCONDUCTING MULTI-CORED STRIP CONDUCTOR FOR ALTERNATING AND DIRECT CURRENT Russian patent published in 2014 - IPC H01B12/10 

FIELD: electricity.

SUBSTANCE: superconducting multi-cored strip conductor of rectangular cross-section contains a matrix of stabilising material with superconducting current-carrying parts placed in it, superconducting current-carrying parts and an external insulating shell; according to the invention in the matrix of the superconducting strip conductor there are superconducting current-carrying parts of circular section, which are placed in the same plane, at that width of the strip conductor is defined by the following ratio: B=N_ccpπd_ccp., and the distance between longitudinal axes of the neighbouring current-carrying parts is equal to: $$a=\frac{в}{N_{ccp}},$$ where d_ccp is a diameter of a current-carrying part, N_ccp is a number of the current-carrying parts in the conductor.

EFFECT: increasing current-carrying capability and power of the superconducting conductor, reducing energy losses in it at the alternating current passage, consumption of electric energy and coolant, simplifying the conductor manufacturing technology.
