Abstract
A transmission cable having a nonhalogenated jacket and a nonhalogenated composition for use as a transmission cable jacket. The jacket is prepared from a nonhalogenated polyolefin based formulation having flame retardant, low corrosivity, low toxicity and low smoke characteristics. The jacket material insulates a core transmission medium such as a metallic conductor or optical fiber. The jacket is extruded about the core or insulator during manufacture. The inventive cable has a jacket formed of nonhalogenated polyethylene and nonhalogenated ethylene vinyl acetate and provides a combination of desired mechanical characteristics, improved performance and manufacturing features while eliminating undesirable corrosive products released during a fire.
