A multi-conductor cable for a vehicle includes core wires respectively having a conductor formed by a plurality of twisted wires, and an insulating layer covering an outer periphery of the conductor, and a sheath layer disposed around the core wires. A marking portion is partially formed on an outer peripheral surface of the sheath layer, and a ratio of an arithmetic average roughness Ra2 of a peripheral region adjacent to the marking portion, with respect to an arithmetic average roughness Ra1 of the marking portion, at the outer peripheral surface, is 0.10 or greater and 0.90 or less.

A wiring harness assembly includes a plurality of electrically conductive wires encased within a substrate formed of a dielectric material, a location feature integrally formed with the substrate, and an opening defined in the substrate located within a predetermined tolerance relative to the location feature. A section of the plurality of electrically conductive wires is exposed within the opening.

Disclosed is a production process for slotting an outer conductor of a leaky cable, through which an integrated production line incorporating a metal strap slotting production line, a metal strap longitudinal coating production line and a sheathing production line is provided. A semi-finished product from a leaky cable insulation process is subsequently processed by laser in a numerical control laser cutting device for cutting out corresponding slot holes in a metal strap to produce a slotted outer conductor. Then the slotted metal strap is embossed, and directly coated on an insulator in a longitudinal coating forming mould of the outer conductor. The final sheathing process is completed in a sheath plastic extruding machine to produce a finished leaky cable product. The processes of the outer conductor of the leaky cable, including the raw material punching, the longitudinal coating forming, and the outer sheathing, are finished at one time.

A cable including a conductor surrounded by a covering layer, the covering layer formed from a thermoplastic vulcanizate composition which includes a continuous phase and a dispersed phase. The continuous phase is formed of a thermoplastic polyolefin. The dispersed phase is formed of a cross-linked elastomeric polyolefin. The thermoplastic vulcanizate composition passes the Hot Creep Test at 150 C. in accordance with UL 2556 (2013) and has a dielectric loss of 3 or less. Methods of forming cables with coverings are also disclosed.

A cable or a line and a method for producing a modified cable sheath (20) of an electric line or a cable (1) are provided and characterized by providing preferably spherical amorphous particles (30), and implanting the amorphous particles (30) into the cable sheath (20) in such a way that a plurality of the amorphous particles (30) penetrate into the surface of the cable sheath (20) just as deep as their diameter, less deep or only minimally deeper. Kinetic energy of the particles during bombardment is selected as a function of particle properties (e.g., size and/or mass) and at least one property of the cable sheath (e.g., strength of the cable sheath) such that the amorphous particles (30) penetrate into the surface of the cable sheath (20) as deep as their diameter, less deep or only minimally deeper than their diameter. The amorphous particles (30) can be glass spheres.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
