ABSTRACT:
Line for transmitting electric energy, with bundle conductors enclosing into the bundle a metal or dielectric cable incorporating optic fibers for telecommuniation. The cable, in correspondence of each spacer of the bundle, is supported in a position placed on the vertical led through the barycenter of the bundle and at a distance from said barycenter included in a range of .+-.35% of the diameter of the bundle (i.e. the diameter of the circumference defined by the barycenters of the subconductors; + for positions above the barycenter, --for positions below the barycenter). The spacers are set at a mutual distance included between 30 m and 85 m. The optic fibres cable is clamped onto each spacer either by means of bolt clamps forming part of said spacer, or by means of helical armor rods wound around the optic fibres cable and around a cable positioning clamp fixedly connected to said spacer.
