AC-Losses of a Prototype 10 kA Cable-in-Conduit NbTi Superconductor for SMES Applications

Hysteresis and Coupling Losses in Superconductors

“…The Ni coating, as well as the Zn, has higher contact resistance and is not sensitive to curing heat treatment and applied load (63). The Cr coating has proved to be effective in cutting the interstrand loss in medium-sized CICCs (64,65). A direct comparison of contact resistance for bare and Cr-and Ni-plated strands indicates almost one order of magnitude higher resistance for Cr than for Ni and another order of magnitude difference between Ni and clean Cu (57).…”
