Abstract:
A self-supporting aerial cable includes an undulated core enclosed in an aluminum, inner shield, a plastic inner jacket enclosed in a steel, outer shield having an unjoined longitudinal overlapped seam, and a plastic outer jacket. The outer plastic jacket includes a first portion which encloses the steel shield and a second portion which encloses a steel support strand that extends longitudinally but which is spaced from the first portion, said first and second portions of the outer jacket being connected by a web. The unjoined seam of the outer shield allows forces which are imparted to the steel shield by its formation to be transferred to the inner jacket and the inner shield which causes the inner shield to engage portions of the core to maintain the core coextensive with the inner and the outer jackets.
