초록 ▼

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.

대표청구항 ▼

An aerial duct having multiple ducts for supporting transmission cable and the like comprising: a first duct formed from a first polymer; a support strand contained within said first duct, said support strand having a sufficient strength to hold the aerial duct suspended between pole supports; a second duct formed from said first polymer, said second duct having an inside surface and an outside surface, said second duct being joined to said first duct; a polymeric inner duct having a low coefficient of friction formed from a second polymer contained within said second duct having an exterior surface and an interior surface; and a multiplicity of ribs formed along the length of the interior surface of said inner duct, said ribs having a predetermined height and being spaced apart a predetermined distance so that valleys are formed therebetween, the inner duct having an internal diameter sufficiently greater than the external diameter of the transmission cable so that the transmission cable may be passed through the inner duct in direct contact with the ribs along the interior surface of said inner duct after the aerial duct has been suspended.
