An electrical cable having improved abrasion resistance, hydrophobicity, and/or UV protecting properties comprises a conductor having a protecting sheath and/or jacket comprising a base polymer (such as a thermoplastic or thermoset) having an abrasion reducing agent, a lubricant, a hydrophobic agent, and/or a UV protecting agent mixed therein. The resulting cable jacket and/or cable sheath defines an outer surface having improved abrasion reduction properties, lubricating properties, hydrophobic properties, and/or UV protecting properties.

Three-wire communication cables are useful for operation with a vehicle as vehicular data communication cables. The cables include a cable core formed of three insulated wires twisted together at a defined pitch and a jacket surrounding the cable core. The cables can meet Mobile Industry Processor Interface (“MIPI”) C-PHY℠ standard (Version 1.2) as well as International Standards Organization (“ISO”) 6722-1 (2011) and 14572 (2011).

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.

Systems and methods for forming insulation on magnet wire are provided. An extruder that includes one or more rotating screws may receive a thermoset polymeric material and process the thermoset polymeric material to increase its pressure and temperature. An extrusion crosshead assembly in fluid communication with the extruder may receive the thermoset polymeric material and press extrude the thermoset polymeric material as insulation onto a magnet wire. A curing device may then cure the extruded insulation material.

Process for manufacturing a power cable includes: providing a power cable core having an electric conductor; providing a copper foil; providing a protective strip over the power cable core, the protective strip having a radially inner and outer surface and being made of copper with a coating; folding the copper foil around the power cable core so as to bring two longitudinal copper foil rims to contact one to the other; welding the two contacted longitudinal copper foil rims thus obtaining a copper sheath in form of a tube with a welding seam; reducing the diameter of the copper sheath to put it into direct contact with the power cable core and the protective strip; heating the protective strip and the copper sheath at a temperature higher than the melting temperature of the coating of the strip so that the coating fuses in the welding seam.
