Abstract: An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of insulated conductors have an inner protective layer extruded thereabout. A plurality of longitudinally extending ribs or fins or exterior ribbed or finned surfaces are formed outward of the inner protective layer between which exist a plurality of voids. An outer insulation layer can be formed in the same operation as the fins or ribbed surface and the inner layer or in a subsequent operation.

Abstract: An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of conductors have an inner protective layer extruded thereabout, a ribbed or finned surface exterior thereto which includes a plurality of longitudinally extending ribs or fins between which exist a plurality of channel regions, an outer insulation layer thereabout, and a material within the channel regions which provides self-sealing properties to the cable, all applied to the conductor as a combined multilayer, the inner layer and outer layer merging to form the fins therebetween.
