Abstract
A dc transport current was applied to the strands of a
Roebel cable at 77 K in liquid nitrogen bath. The inter-strand
contact resistance was measured. It was modified either by
applying a pressure on the cable at 77 K in liquid nitrogen bath
or using different soldering patterns between the strands of the
cable. Magnetization ac losses were measured in frequency range
50 – 200 Hz in applied magnetic field 4 – 70 mT perpendicular to
the broader face of the cable to test the inter-strand contact
resistance effect. High stability and very low level of coupling
losses was observed in the cables even with the lowest interstrand
resistances.
