| 摘要 |
Production of a superconducting tape of the powder-in-tube type comprising multiple filaments (1) of superconducting material embedded in a silver matrix (2) having the properties of a filament thickness of less than about 40 mum and an overall tape thickness in the range from about 0.45 mm to 1.20 mm. A superconducting power cable including a tubular copper former (3) defining a cooling duct (4) about which superconducting tape is helically laid in two layers of either the same or opposite hand. The cable further includes thermal insulation (5), an electrical screen (6), electrical insulation (7), a further electrical screen (8) and containment (9).
