ABSTRACT:
A jacketed electrical cable construction has low smoke and flame spread characteristics so that it is suitable for use in plenum air spaces in buildings with drop ceilings without the need for metal conduits. The cable includes a bundle of conductors which are insulated with poly(vinylidene fluoride), a wrapping of poly(tetrafluoroethylene) impregnated glass tape surrounding the bundle of conductors and a jacket of poly(vinylidene fluoride).
