Abstract
A superconducting wire (1; 31), contains NbTi superconducting material and Cu, with one enclosing tube (2), in particular, a copper enclosing tube. At least three Al blocks (3a-3c) are disposed peripherally distributed in the enclosing tube (2) and at least three sections containing NbTi (4a-4c) are also disposed peripherally distributed in the enclosing tube (2) and separate the Al blocks (3a-3c) from one another in the peripheral direction. The Al blocks (3a-3c) each make large-surface contact with their adjacent sections containing NbTi (4a-4c). A stabilized NbTi superconducting wire is thereby provided, which has low weight and which can be manufactured at low cost. The superconducting wire has a reduced risk of crack formation, in particular, during wire drawing.
