An electric energy transmission aluminum part, an aluminum connector and a copper-aluminum joint. The electric energy transmission aluminum part includes an aluminum body (1) internally provided with a conical insertion hole (11) which penetrates through front and rear ends thereof. The conical insertion hole is provided with a maximum diameter end and a minimum diameter end. Both the aluminum connector and the copper-aluminum joint include the electric energy transmission aluminum part. The electric energy transmission aluminum part, the aluminum connector and the copper-aluminum joint not only avoid an insulation layer (3) from being crimped into a lead portion and increasing a resistance of the lead portion, but also prevent an indentation from being formed on the surface of the insulation layer (3) and causing breakdown, and further reduce an interference with a mating end environment, thus achieving a wide application range. In addition, the copper-aluminum joint can also save the processing working hours and resources.

An apparatus that melts and monitors sleeves for installation onto shielded cables. The apparatus includes a heat source for melting the sleeve, cable supports for supporting the cable during the melting process, a sensor system that is configured to measure a dimension of the sleeve during melting, and a computer that is connected to receive sensor data from the sensor system and send heater control signals to the heat source. The computer is configured to receive dimensional data from the sensor system, monitor that dimensional data by performing a dimensional analysis, and then deactivate or remove the heat source in response to dimensional analysis results indicating that the sleeve is fully melted (in the case of a solder sleeve) or only fully shrunken (in the case of a dead end sleeve) onto the cable.

A bail for forming a mechanical and electrical connection includes an inboard section and an outboard section. The inboard section includes an elongate, electrically conductive multi-strand conductor. The outboard section includes an elongate, electrically conductive solid rod conductor electrically connected to the multi-strand conductor.

The present disclosure describes a power cable connector. The connector includes a main body having a bore therethrough, a first threaded section, and a second threaded section; a back cover having a third threaded section configured engage the first threaded section of the main body; a pair of female conductor pins configured to be coupled to inner conductors of a power cable; an insulator having one or more recesses extending along an outer surface and a fourth threaded section configured to engage with the second threaded section of the main body, the insulator having a pair of inner channels extending therethrough sized to receive the pair of female conductor pins; an end cap including one or more recesses; and a locking nut including one or more protrusions extending radially inward. When the locking nut is inserted onto the insulator and end cap, the one or more recesses of the insulator and one or more recesses of the end cap are configured to receive and guide the one or more protrusions of the locking nut to secure the end cap to the insulator. Connector assemblies are also described herein.

An HVDC power cable joint assembly for jointing more than two power cables, including: a connection body including: a multi-branch conductor having at least two branches and a stem, a multi-branch conductor insulation system including: a connection body inner semiconducting layer arranged radially outside of the multi-branch conductor, a connection body insulation layer arranged radially outside the connection body inner semiconducting layer, a connection body outer semiconducting layer arranged radially outside the connection body insulation layer, N power cables, where N is the number of branches plus one, each power cable having a conductor, and a power cable insulation system surrounding the conductor, N power cable joints, each connecting a branch or the stem to a respective power cable, wherein each power cable joint includes: a conductor joint between one of the branches, or the stem, and a conductor of one of the power cables, a joint insulation system arranged around the conductor joint, the joint insulation system including a deflector layer, a field grading layer, a joint insulation layer and a joint insulation system outer semiconducting layer, and an outer cover housing the joint insulation system, and an external metal casing accommodating the connection body.

A solder sleeve for connecting a wire to another wire or to a terminal device is formed from an alloy comprised of 42 percent tin and 58 percent bismuth that has a eutectic melt point of approximately 138° C. The wire receiving portion, at least one side of the solder sleeve is in the form of a hollow tubular member that is extruded so as to lack a longitudinal seam, the opposing side may be in one of many forms. A thermochromic dye is mixed in with a flux layer located on a portion of the outer surface of the solder sleeve, the dye designed to change from a first color to a second color at the same temperature as the melting point of the alloy. The solder sleeve may be held within a heat shrink tube.
