COAXIAL CABLES HAVING IMPROVED SMOKE PERFORMANCE

A coaxial cable includes an elongate inner conductor. A dielectric laye r surrounds the inner conductor. A first outer conductor surrounds the dielectric layer and has perforations defined therein. A second outer conductor surroun ds the first outer conductor. A polymeric jacket surrounds the second outer conductor. The cable is adapted such that, when the dielectric layer is melted, at leas t a portion thereof and/or smoke therefrom can flow through the perforations in the firs t outer conductor. According to some embodiments, the second outer conductor defines a plurality of voids therein and, when the dielectric layer is melted, at leas t a portion thereof and/or smoke therefrom can flow through the perforations in the firs t outer conductor and into the voids. According to some embodiments, the second oute r conductor is braided.
