Naval power cable comprises a plurality of insulated electrical conductors, at least a pair of strip cords, a water blocking layer, and a jacket layer. Each electrical conductor has a longitudinal extent and is helically intertwined with the other electrical conductors, to form a core conductor assembly having at least a pair of outer interstices adjacent to the insulated electrical conductors. Each strip cord is disposed in and extends along one of the outer interstices of the core conductor assembly. The water blocking layer is disposed about the core conductor assembly and the strip cords, and prevents passage of water along interstices about the electrical conductors. The jacket layer is disposed over and adjacent to the water blocking layer. To provide a power cable construction which has superior physical strength, toughness and resistance to damage, the water blocking layer and jacket layers, are formed from first and second cross-linkable materials, respectively. Preferably, cross-linking is effected throughout the jacket layer, across the interface, and partially into the water blocking layer. Also disclosed is an improved method installing power cable of the present invention aboard naval vessels. The method ensures the formation of improved seals at cable transits, and permits installation of power cable aboard naval vessels with substantial savings in time and effort and added measures of worker safety.
