Abstract : Bowing of aerial cable and its attendant phenomenon, fatigue failure of the metallic sheath of that cable, have been problems since the first lead-sheathed cable was supported by rings from a steel strand. The object of the project was to determine the coefficients of linear expansion of cable structures in order to formulate one tool to be used in two different attacks on the problem of bowing of metallic-sheathed cables: the first consisting of new construction methods to prevent bowing; the second consisting of methods of treating old cable in which the bows had led to an unreasonably high trouble rate.
