Abstract: In this paper we propose a new method using finite elements
modelling to predict the impact of stranding and compacting process on a
conductor electrical resistance. The experimental work has highlighted the
complexity of physical phenomenon within the conductor caused by elastic and
plastic deformations and inters-strands electrical contact resistance. In
reality, electrical performance of a conductor depends on the nature of the
material and its metallurgical state, on the mechanical pressure and electrical
conductance of inter-strands contact areas. For these reasons, mechanical
models have been developed in Abacus software to study different parameters
involved in the stranding and compacting process to determine the actual
conductor shape, strands actual deformations, residual stresses and contact
pressure, etc. The deformed geometries were exported to COMSOL Multi-physics
software using ECAD IMPORT module. DC simulations were, then, performed to
analyze the electrical resistance of the conductor. Finally, the results
obtained by simulation have been compared to the measurements to determine the
accuracy of the models.
