Nbti - superconductor with distributed in the circumferential direction, in order to reduce weight, al - blocks

摘要

Superconductive wire (1; 31), comprising - nbti superconducting material and cu, with– a jacket tube (2), in particular a cu - jacket tube,– with at least three al - blocks (3a, 3c), the distributed in the circumferential direction within the jacket tube (2) are arranged,– and with at least three nbti - glycol-containing sections (4a, 4c), which also distributed in the circumferential direction within the jacket tube (2) are arranged, and which the al - blocks (3a, 3c) separated from one another in the circumferential direction,the al - blocks (3a, 3c) in each case lies flat on their adjacent nbti - glycol-containing sections (4a, 4c) bear.
