Pozycja Dependence of the Contact Resistance on the Design of Stranded Conductors(2014) Zeroukhi, Youcef; Napieralska-Juszczak, Ewa; Vega, Guillaume; Komęza, Krzysztof; Morganti, Fabrice; Wiak, SławomirDuring the manufacturing process multi-strand conductors are subject to compressive force and rotation moments. The current distribution in the multi-strand conductors is not uniform and is controlled by the transverse resistivity. This is mainly determined by the contact resistance at the strand crossovers and inter-strand contact resistance. The surface layer properties, and in particular the crystalline structure and degree of oxidation, are key parameters in determining the transverse resistivity. The experimental set-ups made it possible to find the dependence of contact resistivity as a function of continuous working stresses and cable design. A study based on measurements and numerical simulation is made to identify the contact resistivity functions.
