ABSTRACT:
A dual layer shielded electrical cable is disclosed. The cable has at least a pair of insulated conductors, a metallic shield and a jacket surrounding the shield and insulated conductors. A first jacket layer made of flame retardant material surrounds the insulated conductors. A metallic shield then surrounds the first jacket layer. A second jacket layer then surrounds and seals the metallic shield against the first jacket layer, such that the insertion of the first jacket layer provides the cable with electrical signal attenuation and impedance characteristics equivalent to that of an unshielded cable with similar conductor insulation thicknesses. In another embodiment, a dual layer plenum rated electrical cable is disclosed. The cable has at least a pair of insulated conductors and a jacket surrounding the insulated conductors. Both the first and second jacket layer are made of a low-smoke and flame-retardant materials.
