Beschreibung
Zusammenfassung:	The invention relates to the field of electrical engineering and the creation of long composite wires based on superconducting compounds for use in the manufacture of electrical equipment. Claimed is a blank for producing a long Nb3Sn-based superconducting wire, which consists of a copper jacket, inside which there is a copper matrix having a tin-containing rod at its centre with a plurality of copper-clad rods arranged therearound, wherein the copper matrix is surrounded by a multi-layer niobium diffusion barrier, the plurality of rods consists of rods containing an Nb-Ti alloy and rods made of an Nb-Zr alloy, each rod made of an Nb-Zr alloy being a composite made from Nb-Zr alloy in the form of a core surrounded by a niobium barrier. The technical result is high current carrying capability in a long Nb3Sn-based superconducting composite wire in magnetic fields having a flux density greater than 12 T.
