Abstract

The invention relates to methods of manufacturing superconductive wires including single- and multi-filament wires as well as the wires as such. In according to one aspect of the invention a preform comprising one or more superconductive filament and a primary metal jacket is provided. The preform is arranged in a dummy jacket with a considerably larger external cross-sectional dimension than the primary metal jacket, and the combined dummy jacket with preform is deformed and optionally heated. After deformation the dummy jacket may be removed. This method results in a superconducting wire e.g. a tape which has improved current-carrying capability. In a second aspect of the invention a multi-filament superconductive wire is manufactured by providing a plurality of single superconductive filaments each comprising filament metal jacket, wherein at least one of the filaments has a filament jacket which is thinner than the filament jacket of at least one other of the filaments. The filaments are arranged in an inner jacket which0may e.g. a silver jacket or a dummy jacket. This method is particularly cost-effective, as the amount of material e.g. silver used for the filament jacket may be substantially reduced.
