METHOD FOR PRODUCING LONG HIGH-TEMPERATURE SUPERCONDUCTING PARTS Russian patent published in 1999 - IPC

FIELD: electrical engineering; manufacture of long stranded conductors around high-temperature superconducting compounds. SUBSTANCE: method involves deformation of composite blank built up of sheath and desired number of gaging parts of cut deformed blank to produce long conductor, high-temperature treatment at 830-835 C to obtain superconducting phase of desired composition and definite structure in conductor strands, followed by production of non- homogeneous insulating coat on sheath by covering sheath surface with organometallic compound of metal concentration with 25-40 g/l metal mixture followed by low-temperature treatment at 350-400 C, whereupon conductor is wound. Parts built around such long insulated conductors provide for correcting their design. EFFECT: improved resistance to bending strain due to specific structure of ceramic core and non-homogeneous insulating coat; enlarged functional capabilities. 1 dwg, 1 tbl
