A stress cone for reducing electrical stresses is disclosed for use on terminated ends of tubing encapsulated power cable used in surface applications in a subsurface well power system employing electric submersible pumps (ESPs). The stress cone comprises an annular section about a longitudinal axis for receiving a terminated end of the TEPC in its first end and for abutting the terminated metal TEPC end against a metal shoulder at its second end therein, and an insulation chamber axially aligned with and connected to the annular section. The chamber comprises a metal interior surface symmetrical about the axis. The insulated TEPC core (without outer metal sheath) passes through the insulation chamber along the axis and then exits. The ID of the TEPC metal sheath and the inside metal surface of the chamber form a smooth ground plane transition surface. Insulation material surrounds the TEPC insulation layer within the insulation chamber.

The water blocking gel comprises a polyolefin oil, wherein only a very small fraction of the polyolefin species have a molecular weight below about 2000. The gel also includes a thixotropic agent, and a thermal oxidation stabilizer. The gel is relatively low cost, does not cause substantially swelling of the polyolefin buffer tubes in contact therewith and does not degrade the buffer tube's physical properties.

A watertight inlet device for inserting a cable containing optical fibers into a chamber or a container, e.g. into a splice box. The device includes a metal solepiece for securing the strength members of the optical cable, and which plugs into and fixes to a tubular sealing body equipped with an external O-ring gasket and having its rear portion shaped to form a sealing stuffing box on the outer sheath of the cable. The rear of the nut of the stuffing box receives a clamp for retaining the cable. Once the device has been fitted, the resulting assembly is inserted into the inlet passageway until it abuts against a shoulder in the passageway. Then only the head of the securing solepiece and a groove in the body project inside the container, the groove then receiving a key or fork for retaining the assembly.

The present invention concerns a cable retention device, which also may be used for pipes or wires, to take up forces actuated by or on a cable (2) etc. Each cable (2) is received in a module, formed of two module halves (6, 55, 58, 62). The modules are received inside a rigid frame construction. The modules inside the frame construction are to be compressed. The compression is accomplished by means of a compression unit (36, 41) inside the frame construction and/or by assembly of the cable retention device.

A method for forming a protected disconnectable joint assembly includes providing a disconnectable joint assembly. The disconnectable joint assembly includes: an electrical transmission power cable including a conductor and a cable insulation layer covering the conductor, the conductor having a terminal end; an electrically conductive cable connector affixed to the terminal end of the power cable and having a connector coupling portion; a busbar including an electrically conductive busbar body, a busbar coupling portion extending from the busbar body, and a busbar insulation layer covering the busbar body; and a disconnectable coupling mechanism mechanically securing the cable coupling portion to the busbar coupling portion to provide a joint between the cable and the busbar. The disconnectable coupling mechanism is selectively operable to disconnect the cable connector from the busbar without severing the cable. The method further includes: providing a joint cover assembly including a tubular, elastomeric cold-shrinkable sleeve body; maintaining the joint cover assembly in an expanded state using a removable holdout device mounted within the sleeve body; mounting the joint cover assembly on the holdout over the joint between the cable and the busbar; and thereafter removing the holdout device from the joint cover assembly to release the sleeve body to contract onto the disconnectable joint assembly such that the sleeve body circumferentially surrounds the joint between the cable and the busbar, overlaps portions of the cable insulation layer and the busbar insulation layer adjacent the joint, and applies a persistent radially compressive load on the cable insulation layer and the busbar insulation layer.

A method for selecting components for a mixture to be injected into an interstitial void volume adjacent to a central stranded conductor of an electrical cable segment having the central conductor encased in a polymeric insulation jacket to enhance the dielectric properties of the cable segment. The method includes selecting an anticipated operating temperature for the cable segment to be used in selecting the components for the mixture to be injected into the interstitial void volume of the cable segment and selecting a minimum desired time period to be used in selecting the compounds for the mixture to be injected during which the dielectric properties of the cable segment are to be enhanced by the mixture. Next, first, second and third components for the mixture are selected to provide the cable segment with a reliable life at the selected operating temperature spanning first, second and third time periods, respectively.

A method for forming a connection assembly includes: forming an electrical connection between first and second electrical cables, the first cable including a first primary conductor and a first neutral conductor, the second cable including a second primary conductor and a second neutral conductor; and providing an integral, unitary cover assembly. The cover assembly includes: an inner elastomeric sleeve defining a cable passage to receive the electrical connection and the first and second primary conductors; and an outer elastomeric sleeve surrounding the inner sleeve. The method further includes: mounting the cover assembly on the cables such that the electrical connection and the first and second primary conductors extend through the cable passage; installing a first protective sleeve on a first neutral segment of the first neutral conductor; routing the first neutral segment and the first protective sleeve exteriorly of the outer sleeve to a second neutral segment of the second neutral conductor; and mechanically and electrically coupling the first and second neutral segments to thereby provide electrical continuity between the first neutral conductor and the second neutral conductor.

Methods of fabricating a microelectronic device having improved performance characteristics are disclosed which are characterized by using super critical fluid to perform a material removal step.

A removable cable gland includes a two-piece fitting which may be laterally assembled over a cable, as opposed to a cable being fed through an opening in the fitting. A two-piece compression nut may also be laterally assembled over the cable. The two pieces of the compression nut are slid together along a longitudinal direction of the cable by a tongue and groove arrangement. The two pieces of the fitting are plugged together in a direction perpendicular to the longitudinal direction of the cable. Once first threads of the fitting are engaged to second threads of the compression nut, the two-piece fitting is locked together by the surrounding compression nut. Simultaneously, the two-piece compression nut is locked together, such that the tongue may not slide longitudinally relative to the groove, due to the first and second thread engagement.

When coupled the shoulder portions form tubular projections that hold electrical conduits containing electrical wiring. A gasket is provided between the base and the cover to form a waterproof barrier. The tubular projections are perpendicular to walls of the cover and the base, and allow electrical wiring to be connected from multiple directions within a residence.
