An integral, unitary cover assembly for covering an electrical connection between first and second electrical cables each having a primary conductor and a neutral conductor includes an inner elastomeric sleeve, an outer elastomeric sleeve and an integral jumper assembly. The inner sleeve defines a cable passage to receive the electrical connection and the primary conductors of the first and second cables. The outer sleeve surrounds the inner sleeve. The jumper assembly includes an electrically conductive jumper conductor, a first jumper connector and a second jumper connector. The jumper conductor is interposed between the inner and outer sleeves and has first and second opposed ends. The first jumper connector is mounted on the first end of the jumper conductor and is configured to mechanically and electrically couple the neutral conductor of the first cable to the jumper conductor. The second jumper connector is mounted on the second end of the jumper conductor and configured to mechanically and is electrically couple the neutral conductor of the second cable to the jumper conductor.

A contact region of an electrically conductive member includes a contact area, a shroud and at least one projection. The contact area is provided to electrically engage a mating connector. The shroud is positioned proximate the contact area and is dimensioned to cooperate with a portion of the mating connector to align the mating connector in the contact area. The at least one projection is provided proximate the contact area, such that the at least one projection cooperates with a mating connector to limit the rotation of the mating connector relative to the contact area.

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.

Embodiments of the present invention include a T-body elbow arrestor having an elbow body. A surge arrestor is positioned in one portion of the elbow body extending from an intermediate portion of another portion of the elbow body. An end cap assembly is coupled to the elbow body that is electrically connected to the surge arrestor. A bushing receiving region is positioned in the elbow body extending from the intermediate section towards a first end of the elbow body that is configured to receive a bushing. An insulating plug is positioned in the elbow body extending from the intermediate section towards a second, opposite end of the elbow body. The insulating plug has an end in the intermediate section configured to be coupled to the bushing to secure the T-body elbow arrestor in an assembled condition.

A wrap-around cable sleeve for environmentally sealing a cable section is provided where the wrap-around cable sleeve includes a longitudinally extending body comprising an electrically insulating material and having a longitudinally extending portion with a corrugated lateral cross-section. The longitudinally extending portion has a flexural modulus of between about 4,000 and 100,000 psi. The longitudinally extending portion defines a portion of a cable chamber. The cable chamber extends at least substantially around the cable section when the body is wrapped around the cable section. The cable chamber has a range taking in a radial direction of at least about 15 percent. The present invention may provide a wrap-around cable sleeve for protecting electrical cable sections of various shapes and sizes from the environment, including moisture as well as sharp objects. Methods of making such wrap-around cable sleeves are also provided.

An electrical connector for use with a conductor includes a housing defining a port. The port includes an entrance opening, an exit opening, and a conductor passage extending between and communicating with the entrance and exit openings. The conductor passage is adapted to receive the conductor therethrough. Sealant is disposed in the conductor passage. The sealant is adapted for insertion of the conductor therethrough such that the sealant provides a seal about the inserted conductor. A penetrable closure wall extends across the conductor passage.
