A method can include extruding polyethylene about a lead (Pb) barrier layer disposed about a conductor to form an assembly; and armoring at least one of the assemblies with metallic armor to form a cable. A power cable can include a conductor; a lead (Pb) barrier layer disposed about the conductor; a cushion layer disposed about the lead (Pb) barrier layer where the cushion layer includes crosslinked polyethylene (XLPE); and metallic armor wrapped about the cushion layer.

An implantable device and method of manufacture include a substantially hermetic polychlorotrifluoroethylene (PCTFE) enclosure with closely-spaced wires extending through a slit in the enclosure. A method for manufacturing the implantable device includes cutting a slit in a piece of polymer and extending a plurality of insulated wires through the slit. Each of the insulated wires are parallel to a neighboring wire of the insulated wires. The piece of polymer is thermally bonded around each wire of the plurality of insulated wires such that the piece of polymer is sealed around insulation of each wire with a portion of each wire extending through the piece of polymer.

The present invention relates to a method for producing a flexible substrate. According to the method of the present invention, a flexible substrate layer can be easily separated from a carrier substrate even without the need for laser or light irradiation so that a device can be prevented from deterioration of reliability and occurrence of defects caused by laser or light irradiation. In addition, according to the method of the present invention, a flexible substrate can be continuously produced in an easier manner based on a roll-to-roll process.

A wire harness includes electrical wires and an outer covering member. The outer covering member includes tube portions different in cross-sectional shape and size and a guiding shape portion between adjacent tube portions. The guiding shape portion guides the electrical wires when inserted. A cap is provided to each one end of the electrical wires, and the electrical wires are passed through the guiding shape portion with the caps facing frontward. A wire harness and a method for inserting electric conductive paths through the wire harness can enhance workability related to the electrical conductive paths and an outer covering member while suiting the wire harness to the shapes and the usage environments.

Well intervention apparatus is provided, the well intervention apparatus including a flexible hose to be lowered into a well, a stuffing seal which engages around the hose during lowering, at least one tool provided at a downhole end portion of the hose, and a plurality of individual tubes extending along an inside region of the hose and connecting to the at least one tool, each individual tube providing a fluid path for fluid communication between outside of the well and the at least one tool inside the well, and each individual tube being laterally supported in said inside region such that its lateral movement is restricted.

A technique facilitates construction and operation of a power cable which may be used to deploy an electric submersible pumping system downhole into a wellbore. The power cable is constructed to provide structural support of the electric submersible pumping system while also providing electric power to the electric submersible pumping system when located downhole in the wellbore. The power cable comprises at least one conductor and a plurality of layers selected and arranged to ensure long-term support and delivery of electrical power in the relatively harsh downhole environment.

A flex-resistant shielded composite cable includes a plurality of electric wires, a shielding layer and a tubular sheath. Each of the electric wires includes a conductor part which is composed of a twisted wire, which is formed by twisting a plurality of strands having a diameter of 0.05 mm or more and 0.12 mm or less, a nominal sectional area of the conductor being 8 sq or more, a covering part covering the conductor part. The shielding layer is formed of a braid formed by braiding plated fiber formed by performing metal-plating on anti-tension fiber and covers outer periphery of the plurality of electric wires. The tubular sheath is provided on the outer periphery of the shielding layer and made of an insulating resin.

A composite wiring includes: elastic wiring comprising an elastic tube, a conductor wire disposed inside the tube, and fixing portions that fix the conductor wire and the tube together at both ends of the tube in the lengthwise direction thereof, the length of the conductor wire between the fixing portions when the tube is in an unextended state being longer than the length of the tube between the fixing portions; other wiring separate from the elastic wiring; and a connection member that connects the conductor wire of the elastic wiring and a conductor wire of the other wiring by caulking in a state of being brought into contact with each other, the connection member having an interior section sealed in a watertight manner with a sealing material.
