Abstract
A communication cable includes at least one twisted pair of electrical conductors each having a surrounding layer of electrical insulation formed from fluroethylenepropylene (FEP) and at least one additional twisted pair of electrical conductors each having a surrounding layer of electrical insulation formed from an olefin based compound. The cable includes a cable jacket encasing the at least one twisted pair and the at least one additional twisted pair of electrical conductors. The cable meets or exceeds the requirements of the Underwriter's Laboratory UL Standard 910 Test Method For Fire and Smoke Characteristics of Cables Used In Air-Handling Spaces.
Claims23
A communication cable for use in a plenum, said cable comprising:
- at least one twisted pair of electrical conductors, each of said electrical conductors of said at least one twisted pair having a single surrounding layer of electrical insulation formed from a first material which is fluroethylenepropylene (FEP);
- at least one additional twisted pair of additional electrical conductors, each of said additional electrical conductors of said at least one additional twisted pair having a single surrounding layer of electrical insulation formed from a second material which is an olefin based compound;
- a cable jacket encasing said at least one twisted pair and said at least one additional twisted pair;
- and
- wherein said cable meets or exceeds the requirements of the Underwriter's Laboratory UL Standard 910 Test Method for Fire and Smoke Characteristics of Cables Used in Air-Handling Spaces.
