Method for automated splicing and terminating low, medium, high, and extra high voltage cables
A system and method for additively manufacturing splices and terminations for extra high, high, medium and low voltage power cable includes providing an additive manufacturing machine having at least one print head. Cable ends can be secured within a chamber from which atmospheric air can be evacuated and replaced with non-oxidizing gas. A scanning device can determine the composition and position of the various constituents of the cable ends, from which information a controller can determine the printing sequence and print a termination or splice portion.
CONNECTION JOINT FOR CABLES FOR A CABLE STRINGING PLANT
Connection joint for cables for a cable stringing plant, comprising at least one first tubular element (18) to which a first segment (22) of a flexible member (19) is attached and positioned rotatable, at least with respect to a longitudinal axis (L) of the joint, inside a second tubular element (23) open at a first end and closed at the other end by a bottom wall (25); the bottom wall (25) comprises at least one hole (26) from which a second segment (27) of the flexible member (19) emerges; the second segment (27) is attached to a portion (32) of a third tubular element (31); the second and third tubular elements (23, 31) are provided on opposite ends with a corresponding hole (29, 35) directed substantially in a longitudinal direction and able to house a respective segment of cable (11a, 11b) to be laid.

COLD SHRINK CORE
The present disclosure provides a support core system for deploying a cold shrink rubber over a cable splice connection in an electrical distribution system. The support core system includes a first solid core, a second solid core, and a polyethylene terephthalate (PET) film. The first solid core is configured to fit over a cable in the electrical distribution system and hold a first portion of the cold shrink rubber in an expanded state. The cable includes the cable splice connection. The second solid core is configured to fit over the cable and hold a second portion of the cold shrink rubber in an expanded state. The PET film is positioned between the cold shrink rubber and each of the first solid core and the second solid core.

COVERING PROCESSING TOOL AND COVERING PROCESSING METHOD
Problem: To provide a covering processing tool and a covering processing method that can improve an operation efficiency of covering a cable connection portion. Solution: A covering processing tool is a covering processing tool that performs a covering process of a cable connection portion and is provided with a first tubular unit extending in an axial direction, a second to bular unit disposed so as to surround the first tubular unit on an outer peripheral side, and a third tubular unit disposed so as to surround the first tubular unit on the outer peripheral side. The second tubular unit is installed on the first tubular unit so when extracting a first diameter expansion holding member of the first tubular unit, by supporting the second tubular unit from an outer peripher al side, relative movement in an axial direction and a circumferential direction of the first tubular unit relative to the second tubular unit is suppressed.
Water-stop structure for wire harness
A water-stop structure including a water-stop tube is provided in which the water-stop tube can be brought into intimate contact with a water-stop region in a wire harness having a steep thickness gradient and thus water-stop performance is improved. The wire harness includes a first portion and a second portion that is thinner than the first portion. An inner water-stop tube covers the water-stop region ranging from the first portion to the second portion in a state where the inner water-stop tube is heated and shrunk. An outer water-stop tube covers the inner water-stop tube at a position between a portion on the first portion side and a portion on the second portion side in the water-stop region in a state where the outer water-stop tube is heated and shrunk.
Self-wrappable ePTFE textile sleeve and method of construction thereof
A self-wrapping textile sleeve that is abrasion, arc and water resistant and method of construction thereof is provided. The sleeve includes a wall having opposite edges extending in a lengthwise direction along a central longitudinal axis of the sleeve between opposite ends. The opposite edges overlap one another to form an inner tubular cavity. The wall has warp yarns extending in the lengthwise direction generally parallel to the central longitudinal axis and weft yarns extending generally transversely to the longitudinal axis between the opposite edges. The warp and weft yarns include expanded PTFE yarns, and the weft yarns further include heat-settable thermoplastic yarns. The heat-settable polymeric yarns impart a bias on the wall to bring the opposite edges into their overlapping relation.
LITZ WIRE SOLDER TERMINATION
A method for litz wire termination includes placing a ferrule over exposed conductors on an end of litz wire. The exposed conductors include a portion of the litz wire without an external insulation layer, and a portion at the end of the litz wire protrude past the ferrule. The method includes crimping the ferrule to the litz wire and placing the end of the litz wire with the ferrule in molten solder past the end of the ferrule. The method includes maintaining the litz wire in the molten solder until insulation on conductors of the litz wire is removed from the conductors in the molten solder and solder bonds to the conductors that are within in the molten solder. The method includes removing the litz wire from the molten solder and allowing the litz wire to cool until molten solder bonded to the conductors transitions to a solid state.
TOOL FOR FIXING A TEXTILE SLEEVE ABOUT AN ELONGATE MEMBER TO BE PROTECTED AND METHOD OF FIXING A PROTECTIVE TEXTILE SLEEVE ABOUT AN ELONGATE MEMBER
A tool for fixing a protective textile sleeve about an elongate member contained therein, and method of use thereof is provided. The tool includes a clamp assembly having opposed clamp members. Each of the clamp members has a clamp surface for abutting the textile sleeve. Each of the clamp surfaces includes a plurality of heating members operably connected to a source of power. The heating members within each clamping surface are supported for independent radial movement relative to one another in response to engagement with an outer surface of the textile sleeve to allow the clamp surfaces to automatically conform to the arcuate shape of the sleeve and elongate member being clamped therebetween.
