Purpose: To analyse the phenomena in the stranded cable it is necessary to know how the contact resistance influenced the current repartition in the cable. The aims of our research are to find the dependence of the cable resistance on the design parameters. Design/methodology/approach: When current passes from one wire to another, the crucial parameter is the resistance of the contact region. The paper presents a method by which this region can be identified and relevant resistance measured. Comprehensive simulations were conducted for different types of wires and cables to assess the influence of design parameters on the current distribution and uniformity. Findings: The found in the course of the work was a method of identification of contact resistance and elaboration of parameters dependence. Research limitations/implications: The future research will be focused on the taking into account the nonhomogenity of the contact area. Practical implications: The presented method will by apply for the optimisation of design of the stranded electric power cable. Originality/value: The novelty is in the way the contact region is identified where current passes from one filament to another. Original relationships have been proposed showing the dependence of the contact region resistance on the design parameters of the cable and mechanical stress.
