Flame retardant and smoke suppressant composite electrical insulation, insulated electrical conductors and jacketed plenum cable formed therefrom |
摘要 |
A flame retardant and smoke suppressant electrical insulation composition for an electrical conductor comprises an inner layer and an outer layer. The inner layer, which contacts and surrounds the conductor, comprises a foamed polymeric material selected from the group consisting of polyolefins and polyurethane. The outer layer, which contacts and surrounds the inner layer, comprises a halogenated polymeric material and at least one outer layer additive to render the outer layer flame retardant and smoke suppressant. A flame retardant and smoke suppressant insulated electrical conductor comprises a length of electrically conductive material surrounded by the insulation composition. A flame retardant and smoke suppressant jacketed electrical cable comprises a plurality of insulated electrical conductors. An outer jacket, which substantially surrounds the insulated electrical conductors, comprises a halogenated polymeric material and at least one outer jacket additive to render the outer jacket flame retardant and smoke suppressant.
