OPTIMIZATION OF THE MANUFACTURING TECHNOLOGY OF WIRES BASED ON COPPER-NIOBIUM ALLOY FOR USE IN PULSED MAGNETS
Abstract. Special winding wires for high-field pulsed magnets must possess a combination of mechanical and electrical properties, which are achieved in composite wires based on a deformable copper-niobium alloy. This article deals with the optimization of the design and deformation mode of large-section wires based on a microcomposite copper-niobium Cu-Nb18% alloy to achieve a tensile strength of over 1 GPa while maintaining electrical conductivity of at least 65 % IACS. It is shown that the mechanical properties of the wire are interrelated with the microstructural parameters of the copper-niobium alloy. The results of studies of the mechanical properties of the wire depending on accumulated deformation and the heat treatments applied are presented.
Key words: pulsed magnets, winding wire, composite wire, copper-niobium alloy, accumulated deformation, hot extrusion

RESEARCH OF OPERATIONAL PROPERTIES WATER-SWELLING WATER-BLOCKING TAPES, USED AS PART OF CABLE CONSTRUCTION
Abstract. The article presents the results of research on the import substitution of glue in the composition of water-blocking material. The results of the assessment of the indicators of corrosion activity and toxicity of smoke and gas products during burning and smoldering of water-blocking materials, which are relevant for use in the subsequent assessment of fire safety of cable products in accordance with ГОСТ 31565. The results of a study of the effect of seawater of different concentrations on the water-absorbing properties of water-blocking water-swollen tapes, as well as the results of tests on the storageability of water-blocking tapes for 12 months, are shown.

THERMAL CONDUCTIVITY OF NANOSTRUCTURED INSULATING MATERIAL FOR ELECTRICAL MACHINES
Abstract. This work is devoted to the study of the thermal conductivity of samples of a new nanostructured material, which is used for insulation in electric machines of the LSKV and GSKV types. This article describes a method and presents experimental results for determining the thermal conductivity of these materials at an operating temperature of (250±5) °C. The obtained values of the thermophysical characteristics of the studied samples are necessary for determining the reliability and service life of electric machines.
Key words: composite, nanostructuring, thermal conductivity, insulation material
