    Abstract

    It was demonstrated previously that transverse cable loading due to electromagnetic forces in coils has a strong impact on the inter-strand contact resistance Rc of poloidal field (PF) cable-in-conduit conductors (CICC) for the International Thermonuclear Experimental Reactor (ITER). Continuing the study, two NbTi medium-size CICC's were subjected to cyclic loading up to 40,000 cycles in the Twente Cryogenic Press in order to simulate transversal forces on the strands and to verify their influence on the conductors' contact resistances Rc and AC loss behavior. The results are presented and compared with the data obtained on the other section of the same conductor lengths in the SULTAN test facility and on full size ITER cables tested in the cryogenic press.
