High temperature superconductor processing
HTSC wires and cables based on them enable low-loss current transmission and creation of record current densities for magnetic systems. CJSC SuperOx has the technology of manufacturing HTSC wires with record current-carrying capacity (more than 200 A per 4 mm width) and increased adhesive strength [D. Kolomentseva EUCAS 2023 “High adhesive strength HTS wire” 2MP-OW-02S]. It is possible to design and manufacture cables of arbitrary cross-section (up to 8 kA at 20K temperature and 20 tesla magnetic field) [D. Kolomentseva MT-28 “ High current, low AC loss HTS cable for fusion and high energy physics applications” 1PoM01-08]. Since 2014 CJSC SuperOx has been developing HTSC wires and has a wide range of manufactured products.
