Nb/sub 3/Sn conductors for ac power transmission: electrical and mechanical characteristics
Conference

OSTI ID:7218897
Coaxial cable conductor designs which incorporate a thin Nb tape (approximately 20 ..mu..m thick) reacted to form Nb/sub 3/Sn layers on each side (approximately 5..mu..m each) have been described in a recent review article. The composite is either clad symmetrically with approximately 30..mu..m of copper on each side or asymmetrically with approximately 50..mu..m of copper on one side and approximately 20..mu..m stainless steel on the other. The copper is required for stabilization and the stainless steel provides additional strength which may be required during cable winding, handling and cooldown. The materials choices and trade-offs associated with incorporating low-loss NbSn tapes into this type of composite are described. These include: (1) reducing the overall ac losses arising from the Nb/sub 3/Sn, the unreacted Nb (or NbZr alloy) substrate and the copper/stainless steel laminates and (2) optimizing mechanical properties.
