Abstract：The superconducting magnet system is an important part of the ITER (international thermonuclear experimental reactor), where the CICC (cable-in-conduit conductors) was selected to be the conductor. This paper concerns to the cabling technique for the superconducting cable. The outer diameter controlling technique and the link between AC loss and structure parameters of the superconducting cable are discussed. The factors, such as the tensile of spooling and off-spooling for strands or sub-cables and setting for dies, which impact on the controlling for cabling parameter and the quality for cabling are analyzed. To avoid the elongation or even breakage, on the unit of cabling, the tensile stress of off-spooling for the cabling of the 1st and the 2nd sub-cables must to be controlled smartly in real-time. Both the quantity and setting methods for dies, and controlling method to outer diameter of the final cable are the key factors for cabling. And several different dies and setting modes for dies are necessary to control the outer diameter. The cabling process and the technique route are fixed and a 765m long dummy cable of CICC was manufactured for ITER the last.
