Abstract: An electrically conductive filler. The filler having a substantially non-conductive core and a conductive layer. The conductive layer is wrapped around the core to form a closed loop thereby establishing conductivity from a bottom of the filler to a top of the filler by paths on each of two sides of the filler. Also disclosed is a method of making a web of conductive filler by placing a web of core material onto an interior surface of a web of conductive layer material. The webs of core material and conductive layer material are directed through a forming station for folding the conductive layer around the core.

Abstract: A cable and cable system is provided having a conductor and an insulation layer on an outer circumference of a conductor. The insulation layer is impregnated with a medium-viscosity insulating oil that has a viscosity of 10 centistokes (cst) to less than 500 cst at 60° C. The insulation layer includes an insulating tape that may be one or a combination of composite tape having a polyolefin resin film laminated with a kraft paper on both its sides and an insulating tape including a polyolefin resin film. The cable includes a metal sheath provided on an outer circumference of the insulation layer, and a reinforcing layer formed on an outer circumference of the metal sheath. The reinforcing layer reinforces the metal sheath by absorbing hoop stress exerted on the metal sheath. The cable system includes a submarine-portion cable and a land-portion cable, an oil stop joint box, and an oil feeding tank.

Abstract: The present invention is a low cost coaxial drop cable having excellent flexibility and shielding coverage. The shielded coaxial cable of the invention includes an elongate center conductor, a dielectric layer surrounding the center conductor, an electrically conductive shield surrounding the dielectric layer, a first plurality of elongate wires surrounding the electrically conductive shield, and a protective jacket surrounding the plurality of elongate wires. The elongate wires have an elliptical cross section with a major axis to minor axis ratio of from greater than 1:1 to less than 5:1. The present invention further includes a method of making the coaxial cable of the invention.
