Abstract
A method of compensating for thermal contraction of superconducting and cryo-resistive cables. The method includes the steps of determining a compensation length for a cable such that when the cable is subjected to an operating temperature, the cable is in or near a stress-free state, and installing the cable into a pipe such that portions of the cable extend outwardly past ends of the pipe. The method further includes the steps of marking each end of the cable such that the determined compensation length is visibly shown, forcing the cable into the pipe at an ambient installation temperature such that a cable pattern is formed therein, and maintaining the cable in the pipe to prevent the cable from being pushed out of the pipe.
