Abstract:
The present invention is directed to a hybrid electrical cable (10) providing for power transmission or distribution and data and/or voice signal communications. In one preferred embodiment, the hybrid electrical cable includes a power cable (12) having a group of one or more high voltage power conductors for conducting power and one or more groups of low power signal conductors (30) for transmitting voice and/or data and/or control signals. The cable further includes a power cable insulation jacket (21) overlying the group of one or more power conductors. The power cable insulation jacket includes a soft magnetic material, preferably a soft ferrite magnetic material, for RF absorption. The cable additionally includes an outer grounded metallic jacket (60) or sheath overlying the power cable, the power cable insulation jacket and the one or more groups of low power conductors.
