Title:
METHOD OF PRODUCING A SHEATH FOR A MULTIFILAMENT SUPERCONDUCTING CABLE AND SHEATH THUS PRODUCED
Document Type and Number:
WIPO Patent Application WO2003081104
Kind Code:
A3
Abstract:
The invention relates to a method of producing a sheath for a high-temperature multifilament superconducting cable. According to the invention, the sheath is obtained through the co-extrusion of a cylindrical billet (50) comprising at least two concentric cylinders (52, 54, 56). The invention also relates to a sheath for a high-temperature multifilament superconducting cable which is produced using the aforementioned method. The inventive sheath consists of a tube (10) with a multi-layer wall comprising: a pure silver inner layer (12, 16, 22) and at least one second silver-based alloy layer (14, 18, 24, 26).
