A process for the manufacture of an electric cable for very high voltages, of direct or alternating current, with solid laminated insulation, impregnated with fluid oil or with dry high pressure inert gas, formed by insulating bands of synthetic plastic material, with smooth surfaces spirally wound, essentially characterized by the fact that said smooth surfaces of the data are provided, before application, a thin layer of granular substance able to withstand the action of any impregnating oil, to leave undisturbed the dielectric characteristics of the insulation as a whole and to allow an optimal penetration of the impregnating fluid.
