Abstract

Tension-torsion measurements were made with applied strain on ACSR, AACSR,ACAR, aluminum and aluminum alloy conductors, as well as on groundwires. Results were compared with predictions of a model based on mechanical properties of constituent wires and the geometry of the multistrand cable. True tensile strength of each cable was predicted accurately. Deviations were found in the torque values of cables containing galvanized steel strands. Interstrand friction, not considered in the model, is thought to be responsible for the deviation. Frictionless interaction of strands was found to be a reasonable approximation for aluminum and aluminum alloy stands.
