Abstract
The drawing of a metallic conductor (copper), an isolator (magnesia) and a metallic tube (copper) is one of the commonly used processes to produce electric cables with mineral isolation. In the first part of this paper, an upper-bound approach was used to analyze the cable drawing process without taking into account the winding effect, to evaluate the forming loads and to predict the optimum process conditions. In this second part of the paper, a modified fracture criterion in terms of the maximum tensile stress-strain energy is adopted to predict the workability of the drawing cables with winding. The results of modelling are compared with cable production data.
