ABSTRACT:
The invention relates to ACSR conductors having two or more layers of conductor strands wound helically around a steel core, the layers being wound alternately in right-handed and left-handed helices. The AC/DC resistance ratio of such a conductor can be greatly reduced by appropriate selection of the lay factors of the strand layers in relation to the cross sectional areas of the respective layers. The unbalanced mechanical torque can also be greatly reduced by appropriate selection of the lay factors of the strand layers in relation to the means diameters of the layers and the outside diameter of the conductor.
