Abstract
A plenum rated cable having a core that includes a transmission medium of one or more copper or tin-copper conductors having thereon an insulating layer of an ethylene-chloro tetrafluoro ethylene composition. A first shield surrounds the core and extends longitudinally within and parallel to the length of the cable and includes a first layer of aluminum material and a second layer of cellulose acetate or polypropylene. The first and second layers are bonded together. A second shield surrounds the first shield and extends longitudinally within and parallel to the length of the cable and includes a first layer of aluminum and a second layer of cellulose acetate or polypropylene. The first and second layers are bonded together. A drain wire drains leakage within the cable generated from the current and allows for easy termination of the shield to the connector. A thermoplastic jacket encloses the drain wire and longitudinally surrounds the second shield and is made of a polyvinyl chloride composition.
