8th International Conference on Crack Paths Experimental study of the mechanical behavior of the strain and friction resistance of PVC-coated copper cables Anass Gouya a,* , Maha Hinna b , Mohamed Meziane c , Hassan Chaffoui a , Elhoussine Atmani a a Nanostructure et Matériaux Avancés ,Mécanique et Thermofluide, FST Mohammedia, Hassan II University of Casablanca, BP 146 - Mohammedia, Morocco b Laboratoire de Virologie, Oncologie, Biosciences, Environnement et Energies Nouvelles, FST Mohammedia, Hassan II University of Casablanca, BP 146 – Mohammedia, Morocco c Laboratory of Materials,Energy and Control Systems, Faculty of sciences and Techniques, University of Hassan II Casablanca, Casablanca, Morocco Abstract In applications for renewable energy, as well as in the fields of automotive systems, networking, and information systems, the termination of copper cables with two materials the first of which is an outer insulating material for heavy-duty use and the second of which is an inner conductive material has long been a source of concern. In this work, experimental investigations were carried out on a single heterogeneous sample of different sizes to analyze and compare the performance of wire, strand, and cable diameter (1.2mm, and 1.3mm) for a seven-wire sample as well as cable diameter (2.8mm, and 3.0mm) for a forty-five wire sample. Two experimentaltests were conducted to optimize the mechanical and electrical behavior's characteristics. The experimental set up consisted of an Abrasion Oven machine (friction as a percentage) to determine the resistance of the cable insulation and conductor; a Shimadzu extraction machine; and tensile equipment to test the mentioned strings. Extensive studies were carried out to investigate the impact of different termination designs on rope performance under constant test circumstances. Given the results of the tensile and friction tests, the effects of dimensions on mechanical and electrical behavior can be optimized. The experimental results can be used asa basis for the design of future optimal automotive systems, as well as for the performance of renewable energies in transmitting electrical energy in control and instrumentation signals. © 2025 The Authors.
