which is being participated in by China． CICC ( Cable-In-Conduit Conductors) conductor was deemed to be the preferred
! T5 k  A, h( f5 l3 ~conductor for ITER program due to its lower ac loss． The structure and the cabling process of the CICC conductor
are introduced in this paper． The technique route of cabling has been established． The cabling process and the

diameter of the CICC conductor can be controlled efficiently by multi-rolling die + half-die for diameter controlling
without injure to strands line．
