A flat power cable includes at least two cores of which at least two cores include a power transmissive insulated element and a protective sheath disposed in a radially external position with respect to the power transmissive insulated element. The cores are disposed on a common transversal axis and an outer armour contains the cores. Inside the armour, adjacent cores and an internal surface of the armour delimit empty interstitial spaces. The flat cable includes swellable fillers disposed in the empty interstitial spaces. In a transversal section of the cable, each of the swellable fillers, in an unswelled configuration, presents a cross section area smaller than a cross section area of the respective empty interstitial space. The swellable fillers swell by absorbing fluid the flat power cable is submerged in and enlarge, filling all the interstices, pushing against the cores and the armour and constraining the cable in its flat configuration.
