Abstract
PURPOSE:To reduce bending distortion occurring in a strand to prevent fatigue rupture, or prolong fatigue life by making a wire diameter of the strand arranged in the outer layer to be reduced. CONSTITUTION:The diameter of a wire-state body arranged in the outside of a stranded wire layer excep a strain tension wire or a stranded wire in the center is made to a 80-95 percent of that of a wire-state body arranged in an adjoining inner layer. This allows generated bending distortion at the time of electric wire vibration to be constrained, as a result, for instance, when the diameterreduced wire is used for replacing an existing transmission line, rupture or damage of an electric wire by electric wire vibration can be prevented, or at least life for vibration rupture or damage of the electric wire can be prolonged.
