ABSTRACT:
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 a longitudinal extent and at least a pair of outer interstices adjacent to the insulated electrical conductors. Each strip cord is disposed along the longitudinal extent of the core conductor assembly and extends into and out of the outer interstices in a spatially periodic manner so as to permit the resulting power cable to undergo severe bends during cable istallation. 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. 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.
