<p>An electric cable, particularly for heating systems, has at least one substantially flat conductor arranged within a substantially flat insulating sheath. The conductor is essentially formed by a conducting ribbon joined to an insulating ribbon, and has one or more folding lines extending longitudinally so as to form flaps that are narrower than the two ribbons and are folded onto themselves so as render the outer surface of the conductor an insulating surface.</p> |
