Abstract: The present invention is directed to a high voltage, insulated electrical power cable suitable for use adjacent to one or more low power signal communications conductors in metal or plastic conduit or raceway. In one preferred embodiment, the power cable includes a first group of one or more conductors for supplying power and a power conductor insulation jacket enclosing the first group of one or more conductors. The power conductor insulation jacket includes a soft magnetic material that functions as an electromagnetic field shield in the radio frequency range of approximately 1 megahertz to 400 megahertz thereby protecting the integrity of signals transmitted on the adjacent signal communications conductors.

Abstract: The present invention is directed to a hybrid electrical cable 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 having a group of one or more high voltage power conductors for conducting power and one or more groups of low power signal conductors for transmitting voice and/or data and/or control signals. The cable further includes a power cable insulation jacket 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 or sheath overlying the power cable, the power cable insulation jacket and the one or more groups of low power conductors.

Abstract: An integrated power and data communications hybrid cable assembly for local area computer network is disclosed. The network includes a hybrid cable integrating both power supply and data communications into one physical cable. For each computer workstation served, a length of cable extends between a panel and an outlet. The panel includes a cabinet defining an interior region and an interior barrier dividing the cabinet interior region into a power section and a data section. The interior barrier includes barium ferrite to magnetically isolate the data section from the power section. The hybrid cable is electrically coupled between an outlet and the panel to provide power to a computer workstation electrically coupled the outlet and to provide for data transfer between the panel and the computer workstation.
