How to process it affects the equivalent prediction of the entire conductor performance. According to the traditional composite theory, the following several predictions were carried: only consider the functions of the stainless steel conduit outside the cable body, the double insulation and the double shielding layer; the influence of the flexible cable body is neglect, so only consider the function of its internal helium tube; the material nature of the cable body is assumed the isotropism, which the elasticity modulus is 1-10 GPa (here taking 2 GPa); combining the homogenization theory with the composite damage theory.
