Compressed stranded conductor, insulated electric wire, and wire harness
A compressed stranded conductor includes an inner layer strand having conductive wires which are twisted together, and an outer layer strand having conductive wires which are arranged around an outer periphery of the inner layer strand and are twisted together. The inner layer strand and the outer layer strand are compressed. An inner layer area reduction rate of one conductive wire of the inner layer strand is 29% or more and 32% or less. An outer layer area reduction rate of one conductive wire of the outer layer strand is 6% or more and 11% or less. A difference between the inner layer area reduction rate and the outer layer area reduction rate is 19% or more and 25% or less.
METAL CLAD CABLE HAVING PARALLEL LAID CONDUCTORS
A Metal-Clad (MC) cable assembly is provided. In one approach, the MC cable assembly includes a core having a plurality of conductors laid parallel to one another, each of the plurality of conductors including an electrical conductor and insulation, with or without a jacket layer. The MC cable assembly further includes a metal sheath disposed over the core. In some approaches, the MC cable assembly further includes an assembly tape disposed around the plurality of conductors. In some approaches, the MC cable assembly further includes a subassembly having a set of conductors, and an assembly jacket layer disposed over the subassembly. In some approaches, a polymeric protective layer is provided over an insulation layer of one or more of the plurality of conductors and the subassembly. In some approaches, a bonding/grounding conductor may also be cabled with the plurality of conductors.
EQUIPOTENTIAL MAT USING WIRE MESH NETTING
Disclosed is an equipotential (EPZ) matting for creating an equipotential zone at a work site. A wire mesh of the EPZ matting is constructed by first cutting desired lengths of cable and laying the lengths of cable parallel and adjacent to each other. The cables are then connected to one another at regularly spaced intervals along the cables using pressed metal ferrules. The connections are staggered as between adjacent cables to create an evenly spaced, open mesh pattern when the wire mesh is tensioned perpendicularly to the longitudinal axes of the cables when initially laid along side one another. The wire mesh is opened and pulled tight for use as EPZ matting on the work site. After work is completed, the mesh is closed and bundled for transport, storage, and re-use.
CABLE WITH NON-CIRCULAR GROUND WIRES
A cable with a non-circular ground wire is provided, including two wires, two ground wires, and an insulating tape; wherein the inner sides of the wires are in contact with each other; the ground wires are respectively arranged on two opposite sides of the wires; each ground wire at least includes a first side, a second side, and a third side; the first and second sides respectively contact the outer surfaces of the two wires, and the shapes of the first side and the second side respectively correspond to the shapes of the outer surfaces of the two wires; the insulating tape covers the outer surfaces of the wires and the third sides of the ground wires. Thereby, the mechanical properties of the cable of the present invention, such as small impedance variation of high-frequency signal transmission, transmission stability, structural flexibility and bending, can be significantly improved.
Method for producing a multi-core cable and correspondingly produced cable
A method for producing a multi-core cable includes arranging first and second contact elements in a contact carrier having first and second longitudinal channels connecting a contacting side to a cable side, and first and second through-openings respectively crossing the first and second longitudinal channels, and a second through-opening crossing the second longitudinal channel. The first and second longitudinal channels and the first and second through-openings are sealed in a fluid-tight manner by inserting two first sealing pieces into the first through-opening and two second sealing pieces into the second through-opening. In an injection-molding method, a connecting piece is formed connecting the contact carrier to the outer sheath of the cable by overmolding at least a rear section of the contact carrier comprising the first and second through-openings and a section of the cable protruding on the cable side.
FIBER-REINFORCED COMPOSITE CABLE WITH TOW AND POWER TRANSMISSION LINE
Provided is a cable including a stranded member floating-preventing element that can be easily peeled off.
A power transmission line core includes one core member and six side members twisted around the core member, each member obtained by impregnating a fiber bundle including a plurality of carbon fibers that are continuous in the longitudinal direction and bundled into the fiber bundle with a resin and curing the resin. A tow including a plurality of tow fibers that are continuous in the longitudinal direction and arranged flatly and densely is spirally wound around the surface of the power transmission line core in the direction opposite to the twisting direction of the side members. The tow is detachably entangled in the unevenness on the surface of the power transmission line core.
SEAL STRUCTURE FOR MULTICORE CABLE, AND SEAL MEMBER
A seal structure that includes: a multicore cable in which first to fourth electrical wires are enveloped by a sheath, the electrical wires extending out from an end portion of the sheath; a rubber plug through which the electrical wires pass, the rubber plug being fitted around the end portion of the sheath; a cap that is fitted around the rubber and presses the rubber plug inward; and a crimping member that is arranged adjacent to the rubber plug and is crimped around the sheath. The crimping member has a locking piece and a mating portion, and the cap has an extending piece and a receiving recession portion. Relative positions of the crimping member and the rubber plug are held by the mating portion of the locking piece and the receiving recession portion of the extending piece locking together.
FIELD GRADING MEMBERS, CABLES HAVING FIELD GRADING MEMBERS, AND METHODS OF MAKING FIELD GRADING MEMBERS
A field grading composite body includes a polymeric matrix and a particulate filler distributed within the polymeric matrix. Particles of the particulate filler include a core formed from a semiconductor material, an oxide mixed layer deposited on the core, and conducting oxide layer. The conducting oxide layer deposited on the oxide mixed layer to provide an electrical percolation path through the polymeric matrix triggered by strength of an electric field extending through the field composite body. Conductors and methods of making field grading composite bodies for conductors are also described.
Multi-Core Cable and Production Method Therefor
