A simple model was developed to predict the plastic behavior of a stranded conductor under tensile loading to fracture. Two cases are considered; the torque transmitted in the case of conductors with fixed extremities and the rotation angle in the case of free rotating conductors. The permanent set caused by bending and torsion during the stranding process associated with conductor fabrication was taken into consideration. The model predicts maximum failing load and total elongation, parameters currently used for design and selection of conductors.
