Abstract
A method for manufacturing a superconducting hollow conductor, with superconducting conductor strands arranged in the interior of a tube through which coolant flows, which allows simple manufacture of long conductor sections, includes enclosing the helical conductor strands in a longitudinally welded tubular carrier body and subsequently drawing the carrier body to an inside diameter which is smaller than the original outside diameter of the helical conductor strands to obtain a mechanically strong conductor arrangement with a defined uniform flow cross-section for the coolant.
Claims5
A method for manufacturing a conductor arrangement of superconductive conductor strands, in which the conductor strands rest in helical fashion against the inside wall of a tubular carrier body, comprising:
- (a) winding the conductor strands to form a helix which has a hollow central part;
- (b) arranging the hollow helix in a tubular carrier body;
- and
- (c) subsequently deforming the tubular carrier body by drawing or rolling into a tube of smaller inside diameter than the original outside diameter of the helix made up of the helically wound conductor strands to thereby increase the pitch of the helix causing large spaces to be formed between turns but without cross section reduction of said strands.
