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.
