The present invention includes a high performance communications cable that provides for reduction or elimination of cross-talk between transmission media in combination with power conductors for wireless fidelity applications and includes one or more core support-separators having various shaped profiles which define a clearance to maintain a spacing and/or channel between the transmission media or transmission media pairs as well as for the power conductors. The core may be formed of a conductive or insulative material to further reduce cross-talk that is comprised of principally polymer blends that include olefin and/or fluoropolymer and/or chlorofluoropolymer based resins with and without inorganic additives. These unique blends offer both flame and smoke suppression while maintaining the characteristics necessary to improve electrical performance and allow for severe cost reduction over conventional separators. These polymers blends can also be utilized for fabricating shielding materials. The specially shaped core support-separators can be either interior to the cable jacket or be employed singularly without the benefit of a jacket and extend along the longitudinal length of the communications cable. Alternatively, with no jacket for cable completion, a portion of the separator wherein a thin layer of material can act as a type of skin for future mechanical protection is provided. The specially shaped core support-separators have both a central region as well as a plurality of shaped sections that extend outward from the central region that are either solid or partially solid, foamed or foamed with a solid skin surface. |
