Abstract

One kind of highly flexible REBCO cable (HFRC) has been proposed recent years, which contains REBCO superconducting tapes wound onto a spiral tube. Under external loads, spiral tube is prone to complex deformation, leading to unpredictable characteristics of HFRC. In this paper, we analysis the deformation process of spiral tube under tension and torsion. Based on the geometrical relationship between tapes and spiral tube, the mechanical behavior of tapes in HFRC is further studied.
