ELECTRIC CABLE WITH UNDULATED TUBING SEGMENTS FOR SUSPENSION IN A WELL SYSTEM AND METHOD OF ASSEMBLY THEREOF
An electric cable for powering a downhole tool in a wellbore. The electric cable includes a core including one or more electrically conductive wires and one or more electric insulating layers surrounding the conductive wires; a metal inner tube surrounding the core, where the metal inner tubing and the core includes one or more undulated segments with one or more curved outer extensions projecting outwards from a longitudinal axis of the electric cable; and an outer encapsulating tube surrounding the core and metal inner tube, where the outer surface of the metal inner tube has outermost portions at the curved outer extensions of the undulated segments that touch an inner surface of the outer encapsulating tube. A well system including the electric cable and a method of assembling the electric cable are also disclosed.
Seamless electrical conduit
Embodiments of the present disclosure generally relate to a unitary electrical conduit that includes a central conductor, a socket coupled to a first end of the central conductor, a male insert coupled to a second end of the central conductor a dielectric sheath surrounding the central conductor, and an outer conductor surrounding the dielectric sheath, wherein a substantially 90 degree bend is formed along a length thereof.
APERIODICALLY OVERLAPPING SPIRAL-WRAPPED CABLE SHIELD SYSTEM
An aperiodically overlapping spiral-wrapped cable shield system includes a cable having cable components such as a pair of conductors, at least one insulator surrounding the pair of conductors, and at least one drain wire. The cable also includes a cable shield that is spirally wrapped around the cable components with a varying wrap pitch that provides a plurality of overlapping cable shield portions with varying overlap areas. When signals are transmitted using the cable components in the cable, the varying overlap areas of the plurality of overlapping cable shield portions create a plurality of varying LC circuits that are configured to generate a resonance that does not exceed a signal integrity resonance threshold for a signals.
Pest-resistant cable jacketing
A protective jacket for cable includes (a) an exterior layer (1) free of a pest repellant, and (2) having external and internal facial surfaces; (b) an inner layer (1) having a shore d hardness of equal to or greater than (≥) 63, (2) including a pest repellant, and (3) having two facial surfaces; and (c) optionally, a tie layer in contact with the internal facial surface of the exterior layer and a facial surface of the inner layer.
Method of manufacturing electrical cable, and resulting product, with reduced required installation pulling force
Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
Method of manufacturing a non-circular electrical cable having a reduced pulling force
In various embodiments, a non-circular electrical cable having a reduced pulling force attributable to the exterior surface of an outer sheath, and method of producing the same is provided. In various embodiments, an outer sheath of the cable may comprise a first and second sheath layer, the second sheath layer being located external to the first sheath layer, and comprising a nylon material configured to reduce the pulling force necessary for installing the cable. In various embodiments, the first sheath layer may be extruded using a tube extrusion method into a substantially circular shape, and the second sheath layer may be extruded using a pressure extrusion methods onto the exterior surface of the first sheath layer while maintaining the at least substantially circular shape of the sheath. The sheath may then be pulled onto the surface of a plurality of conductors to form the non-circular electrical cable.
Automobile architecture
An automobile architecture includes a composite cable, a main electronic control unit, a subsidiary electronic control unit, a motor sensor, and a wheel velocity sensor. In the architecture, the composite cable connects the main electronic control unit and the subsidiary electronic control unit, and the motor sensor and the wheel velocity sensor are connected to the subsidiary electronic control unit.
Mounting and cathodic protection
Methods and apparatus are disclosed. The apparatus includes a substantially cylindrical mount body (350) comprising a first open mouth at a first end of the cylindrical body (350) and a further open mouth at a remaining end of the cylindrical body, a substantially cylindrical inner surface, and an outer surface that includes a plurality of spaced apart substantially parallel recessed regions that extends circumferentially around the body, wherein the cylindrical body (350) is tapered at each end and at least one securing element is located between the recessed regions.
Wiring member with resin molded portions and bracket
A wiring member includes wires, a resin molded portion that covers the wires, and a bracket attachment that is attached to the resin molded portion. The resin molded portion includes a bracket attachment portion that is formed with at least one flat surface portion. The bracket includes a first attachment portion that is configured to be attached to an attachment location, and a second attachment portion that is connected to the first attachment portion and is crimped to the bracket attachment portion while being in surface contact with at least one of the at least one flat surface portion.
End structure and sleeve of shielded cable
An end structure of a shielded cable 10 includes a core 11, an insulator 12 for covering the core 11, a foil 13 for covering the insulator 12, a braided wire 14 for covering the foil 13, a sheath 15 for covering the braided wire 14 and a sleeve 17 arranged between the braided wire 14 and the foil 13 exposed from an end part of the sheath 15. The end part of the sheath 15 and the sleeve 17 are separated from each other to form a clearance 50.
