ABSTRACT:
An aerial duct having a first duct in which a support strand is contained for aerially mounting the aerial duct, and a second duct in which an inner duct or liner is contained through which a transmission or other cable is strung. A multiplicity of support strands or several braided support strands could be contained in the first duct. The first duct and second duct are joined by an intervening web so that the first and second duct have substantially parallel longitudinal axes. The inner duct has spaced apart ribs formed within its inner surface. Valleys are formed between the spaced apart ribs and adapted to retain lubricant placed therein for facilitating the passage of a transmission or other cable through the inner duct. The ribs can be either longitudinal, corrugated or spiral. If desired, the aerial duct and support strand could be made of an all-dielectric material.
