DOWNHOLE CABLES AND METHODS OF MAKING THE SAME
A method and method of using a cable that includes a cable core. The cable core has an inner armor wire layer disposed thereabout. The inner armor wire layer has an outer armor wire layer disposed thereabout. The inner armor wire layer and outer armor wire layer have torque removed therefrom during manufacturing.
HEAT-SHRINKABLE TUBE, HEAT-SHRINKABLE CAP, AND METHOD OF WATERPROOFING ELECTRICAL WIRE BUNDLE
A heat-shrinkable tube or heat-shrinkable cap includes an adhesive layer disposed on the inner surface thereof, the adhesive layer including a low-viscosity adhesive layer formed of a resin having a viscosity of 10 Pa.Math.s or less at a shear rate of 1 s.sup.1 at the heat shrinkage temperature and a viscosity of 100 Pa.Math.s or more at a shear rate of 1 s.sup.1 at the maximum continuous use temperature. The heat-shrinkable tube or heat-shrinkable cap is used for waterproofing an exposed portion of electrical wires of an electrical wire bundle such as a wire harness, in which merely by placing the heat-shrinkable tube or heat-shrinkable cap over the exposed portion of electrical wires, waterproofing and water blocking between strands can be achieved, and outflow of the resin during heat shrinking does not occur. A method of waterproofing an electrical wire bundle uses the heat-shrinkable tube or heat-shrinkable cap.
CABLE HARNESS AND METHOD FOR PRODUCING THE CABLE HARNESS
A method for producing a cable harness, in particular for the motor vehicle industry, includes combining a plurality of individual lines into a line bundle. The line bundle is provided with a bundling element. The bundling element is constructed as a textile-like fiber interlacement or weave which is produced by applying a suspension including fibers and a binder to the line bundle. A cable harness produced by the method is also provided.
Cable, in particular for downhole use, and method of manufacturing such cable
The disclosure relates to a cable (100) comprising a core (102) and a plurality of reinforcing elements (107) arranged around the core (102) so as to cover the core (102), wherein each reinforcing element (107) includes at least a bundle of reinforcement fibers comprising at least one fiber and a thermoset matrix impregnating the bundle of fibers, wherein each reinforcing element (107) is individually tubed with a thermoplastic coating (112).
Downhole Cables and Methods of Making the Same
A cable that includes a cable core. The cable core has an inner armor wire layer disposed thereabout. The inner armor wire layer has an outer armor wire layer disposed thereabout. The inner armor wire layer and outer armor wire layer have torque removed therefrom during manufacturing.
FLEXIBLE ELECTRICAL CONDUCTOR COMPRISING ELEMENTS CONNECTED TO ONE ANOTHER BY TIG WELDING, AND METHOD FOR MANUFACTURING SUCH A FLEXIBLE ELECTRICAL CONDUCTOR
A flexible electrical conductor including an assembly comprising a flexible conductive core made of a first metal material and a sheath covering the conductive core and made of a second metal material having an electrical resistivity higher than the electrical resistivity of the first metal material; a first connection strip formed at least in part by the second metal material and connected to a first end of the assembly, wherein, at the first end of the assembly, the sheath and the first connection strip are bonded by TIG welding, and the conductive core and the first connection strip are bonded by fillet-brazing or soldering.
Apparatus for removing foil shield from cable
A system for removing a foil shield from a cable comprises an induction coil for inductively heating the foil shield of the cable, a cable feeding device for selectively passing the cable through the induction coil, a cutting blade for selectively removing at least a portion of the cable, and a sensor for detecting at least one characteristic of the cable.
Conductor blocking by means of intermittent filling with two component hardening composition
The present invention relates to the technical field of subsea power cables. More specifically, the invention relates to a subsea power cable comprising at least one cable core comprising a bundle of metal wires and more than one layer of a cured two-component hardening composition, wherein the more than one layer of the cured two-component hardening composition is intermittently provided along the longitudinal direction of the power cable. The present invention further relates to a method of manufacturing the power cable according to the invention.
