Abstract
The present invention provides two ribbon cable for conducting AC power and digital data signals respectively. A pliable insulating material holds together and electrically insulates the conductors on each ribbon cable. Conductive material, such as a conductive foil or conductive plastic serves to shield the electromagnetic interference generated by the transmitted AC power from the data conductors. The ribbon cables are folded in a protective outer jacket so that the conductive material is disposed substantially between the power conductors and the data conductors. This maximizes the electromagnetic interference shielding of the conductive material.
