A single-core wire that is to be connected to a core wire of a coated electrical wire in which the core wire obtained by combining a plurality of element wires is coated with an insulating coating, including: a main portion in the shape of a solid bar extending in an axial direction; and an electrical wire fixing portion constituting part of the main portion, and having an inner wall arranged around an outer circumference of the core wire before the core wire is fixed and formed so as to be continuous, in which the core wire is fixed in a state of being surrounded by the inner wall.

In a joining method of an electric wire, an end of a first conductor is held by a holding surface of a first jig electrode from an outer circumference side and an end of a second conductor is held by a holding surface of a second jig electrode from an outer circumference side to butt and join the ends of the first conductor and the second conductor in the axial direction while heating the ends. Then, a melted material is bulged outward from an outer circumferential surface of a joining portion to a bulge molding portion formed to surround a joining portion of the ends of the first conductor and the second conductor.

A method of manufacturing a wire with a terminal includes a crimping process of crimping a crimping terminal on a wire by a terminal crimping apparatus that includes a first mold including a supporting surface supporting the crimping terminal, and a second mold disposed to face the supporting surface and including a recessed wall surface. The recessed wall surface includes a first wall surface and a second wall surface, and a third wall surface curved toward an opposite side of the supporting surface. The first wall surface and the second wall surface include inclined portions and parallel portions. The inclined portions are inclined with respect to the stroke direction so that an interval in the width direction becomes narrower toward the third wall surface. The parallel portions are parallel to the stroke direction. In the crimping process, the side wall surfaces of the first mold face the inclined portions in a state in which the first mold and the second mold come closest to each other in the stroke direction.

The present invention discloses a manufacturing process for a termination injection molding stress control module for cross-linked polyethylene insulated cable body, which comprises the steps of melting and cross-linking a cable factory insulation layer and a filling insulation; melting and cross-linking the cable factory semiconducting layer and a filling semiconducting layer; and melting and cross-linking the filling insulation and the filling semiconducting layer.

A wire overmold device including a carrier body having a distal end and a proximal end, a wire cap configured to engage the distal end of the carrier body, at least one of a jacketed cable and one or more wires at least partially enclosed between the wire cap and the carrier body, and an overmold formed over the proximal end of the carrier body and at least portions of the wire cap and the distal end of the carrier body, wherein the wire cap and the distal end of the carrier body protrude from the overmold.

Aspects of the present disclosure relate to providing cable assemblies for cellular base stations having remote radio head units located atop a radio tower. Each installation requires near-custom cabling, as the electrical resistance of the conductors of the cable assembly varies based on the length of the cable assembly, and because different operators and local governments require different color-coding of the conductors which are coupled to the power trunk. Accordingly, a power distribution system is provided herein wherein conductors of a trunk cable may be coupled to power jumper conductors at transitions. The transitions are generally cylindrical and comprise channels into which splicing lugs are seated. The conductors may be electrically coupled together and secured via set screws. Manufacturing costs may be reduced, as common configurations of trunk cables may be manufactured in higher quantity and coupled to power jumper conductors according to local requirements.

An energy kite may be coupled to a tether and ground station. The tether or other cables may need to be terminated, where one or more components of the cable need to be separated and terminated individually. In energy kite systems, it is common for the tether (or other cables) to have small mass and diameter. The termination may also include a first potted region with a softer potting material and a second potted region with a harder potting material.

An insulation system for jointing of high voltage conductors has an inner layer made of a crosslinked first polymeric semiconducting material, an intermediate insulating layer made of a thermoplastic polymeric insulating material, and an outer layer made of a second polymeric semiconducting material. The insulation system is adapted for surrounding the electric conductor joint.

A method of manufacturing flexible joints (300) in power cables (100, 200) is described, along with a corresponding system (400, 401). The flexible joints are made by joining the conductors (310, 320) of two cable sections to form a joint section (300) with a region of exposed conductor (22); fitting a mould (402) around at least a portion of the region of exposed conductor (22); and forcing a casting material (409) into the mould by transfer moulding to form an outer layer (350) around the region of exposed conductor (22).

This invention relates generally to connectors for wiring applications, more specifically, to a low signal loss (low impedance), shielded cable splice crimp ferrule system. A precision sized splice crimp ferrule is installed using a standard hand crimp tool with an associated symmetrical geometry die and positioner. When employed with other components to terminate the dielectric and the metallic shield over the metallic braid of a cable, the splice crimp ferrule system results in a low signal loss, shielded cable repair that can be used in many types of cable systems.
