A shield wire is formed of eight twisted insulated core wires 1, an inclusion 2 between these respective insulated core wires 1, a tape 3 laterally wound around an outer periphery of a core formed of the insulated core wires and inclusion, a drain wire 4 disposed on an outer surface of the tape, a conductive fiber braided body 5 formed on an outer peripheral surface of the tape so as to interpose the drain wire, a sheath 6 that forms an outer peripheral surface of the braided body, and an adhesive layer 7 between the braided body and sheath. A braided body 5 is adhesively integrated to the sheath 6 by an adhesive layer; thus, the braided body 5 is stripped with the sheath. This eliminates a need for a removal work of the braided body after stripping the sheath, thus ensuring good workability of the terminal processing.

A wiring harness includes an electric wire having a conductor part and an insulator, the insulator covering an outer periphery of the conductor part and containing a plasticizer, and a coaxial wire having an internal conductor, an internal insulator, an external conductor, and a sheath, the internal insulator provided on an outer periphery of the internal conductor, the external conductor provided on an outer periphery of the internal insulator, and the sheath covering an outer periphery of the external conductor. The coaxial wire is arranged adjacent to the electric wire. The coaxial wire comprises a film layer which is provided between the internal insulator and the external conductor and which prevents transfer of the plasticizer. A contact force between the internal insulator and the film layer is 1N or more.

A shielded electrical cable includes a conductor set and two generally parallel shielding films disposed around the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a parallel portion wherein the shielding films are substantially parallel. The parallel portion is configured to electrically isolate the conductor set.

A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

A shielded electrical cable includes a conductor set and a shielding film. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding film includes a cover portion partially covering the conductor set, and parallel portions extending from both sides of the conductor set.

A cable includes one or more conductor sets. Each conductor set includes one or more central conductors surrounded by a dielectric material. Shielding films are disposed on opposite sides of the conductor sets. In cross-section, cover portions of the shielding films in combination substantially surround each conductor set, and pinched portions of the shielding films in combination form pinched portions of the cable on each side of each conductor set. For at least one shielding film in a pinched portion, the conductive layer, but not the non-conductive layer, includes a break.

High reliability power cables for subsea application are provided. Example power cables provide enhanced resistance to partial discharge dielectric breakdown as well as resistance to explosive gas decompression, by eliminating micro-defects and voids at the interface between the insulation layer and the barrier layer during the cable manufacturing process. Lead metal, which is conventionally extruded as a primary barrier layer, is replaced in the example power cables by a gas-and-fluid-resistant thermoplastic that is co-extruded or tandem extruded with surface-modified insulation to promote bonding between the two layers. Elimination of lead metal in the example power cables also significantly reduces their overall weight. The improved resistance to partial discharge and resistance to rapid gas decompression translates to lower workover and lower cost of ownership.
