An electric installation cable in which the insulated wires forming the core and serving to conduct electricity are bound together as one unit. For the simultaneous, undisturbed utilization of the cable for high frequency signals, the unit is made up of 4 cores (A) bound together to form a star-quad. A shield (3) made up of a plastic film (8) coated on both sides with aluminum is arranged over the cores (A). Tinned copper wires (4) are wrapped around the shield (3) to function as a ground wire (4) and a coat (5) of insulation material is arranged around the tinned copper wires (4).
