Abstract

The present invention includes a high performance communications cable exhibiting reduced cross-talk between transmission media with one or more core support-separators having various shaped profiles defining a clearance that maintains spacing between transmission media. The core is formed of a conductive or insulative material to further reduce cross-talk and improve other electrical properties in addition to reducing flame and smoke spread. The cable and separators are comprised of polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins with and without inorganic additives including nano-clay composites. The core support-separators have both a central region and a plurality of shaped sections that extend outward from the central region and are solid, or partially solid, foamed, or foamed with a solid skin surface. In addition, the invention includes the incorporation of hollow ducts used to provide a pathway for conductor media before, during, or after installation of the cable.
