Outdoor overhead supported transmission and distribution electrical and communication covered conductor and cable, whether the exterior cover is metal or plastic, is shiny and visible when newly installed in public view. These products may not become significantly dull until after many years of outdoor weathering. Many utilities have had to bury their transmission and distribution lines or building service drops because the public protested seeing them. This invention is for conductors which are inconspicuous and blend into the environment where they are to be used and the public would object if they were conspicuous. The exterior surface of the covers of these linear bodies are dulled or intermittently dulled so that they are not conspicuous and objectionable to the public. Non-specular jacketed light wave conductors are included. Several methods are claimed for these non-specularly dulled or camouflaged products. Cost and service life benefits are indicated for the plastic covered products. Non-specularly dulled and covered wire rope products are included.
A covered plurality of insulated conductors, which comprise:
A multi-sheathed gas pressurized communication cable with a plurality of insulated conductors, wherein the improvement comprises:
A covered communication cable with a plurality of insulated conductors, wherein the improvement comprises:
