An electric energy transmission aluminum part and a machining process therefor including an aluminum conductive device (1) and an aluminum cable, with the aluminum cable including an aluminum conductive core (2) and an insulation layer (3) cladding a surface of the aluminum conductive core (2). An exposed section of the aluminum conductive core (2) with the insulation layer (3) stripped from the aluminum cable and at least part of the aluminum conductive core (2) clad with the insulation layer (3) are crimped inside the aluminum conductive device (1). A transition section (4) with a trapezoidal axial cross-section is provided at a junction between the insulation layer (3) and the exposed section of the aluminum conductive core (2) in the aluminum conductive device (1). Taking the transition section (4) as a demarcation point, an inner diameter of an end of the aluminum conductive device (1) that is crimped with the insulation layer (3) is greater than an inner diameter of an end of the aluminum conductive device (1) that is crimped with the aluminum conductive core (2). At least one concave structure is provided on a periphery of the aluminum conductive device (1). The concave structure provided on the surface of the aluminum conductive device (1) can effectively prevent the aluminum conductive device (1) from moving relative to a clamp, so as to solve the problem of displacement or rotation of the aluminum conductive device (1) in the clamp during welding, and improve the welding efficiency and the yield.

A method can include extruding an electrically insulating elastomeric compound about a conductor where the electrically insulating elastomeric compound includes ethylene propylene diene monomer (M-class) rubber (EPDM) and an alkane-based peroxide that generates radicals that form decomposition products; cross-linking the EPDM via radical polymerization to form an electrically insulating layer about the conductor; heating the cross-linked EPDM to at least 55 degrees C. to reduce the concentration of the decomposition products in the electrically insulating layer; and disposing a gas barrier layer about the electrically insulating layer.

Flexible cables may include multiple power, ground, and signal traces, and include EM interference suppression devices within the cable itself. Signal traces may be shielded by ground traces. The body of a cable may be divided into lateral portions through which different types of traces extend. One lateral side of a cable body may include a stack of power traces, while another lateral side of the cable body may include ground and signal traces. EBG patterns may be incorporated into ground traces. Capacitors may be positioned within the cable along its length, mounted between power and ground traces, for decoupling.

A purpose of the present invention is to make a wiring member easy to bend in a suspension wiring module connecting a vehicle body-side device and a vehicle wheel-side device. This suspension wiring module comprises a suspension wiring member, which includes a transmission line main body and one or more covering layers covering the transmission line main body. At least one section of the suspension wiring member is a cabin-external section that is positioned outside of the cabin of the vehicle. In the cabin-external section, an arc-shaped groove is formed in an outer covering, which is the covering layer that is located furthest to the outside among the one or more covering layers.

In a base member arrangement section, a plurality of wire-like transmission members are divided into at least a first wire-like transmission member bundle and a second wire-like transmission member bundle, and the cover member is fixed to the base member at positions on both sides of the first wire-like transmission member bundle and the second wire-like transmission member bundle and a position between the positions on the both sides to cover the first wire-like transmission member bundle and the second wire-like transmission member bundle. In a non-base member arrangement section, the plurality of wire-like transmission members include a large bundle part where the first wire-like transmission member bundle and the second wire-like transmission member bundle are bundled together.

A composite cable is provided with plural wires each having a metal conductor and an insulator, a binder layer that bundles the plural wires together, a shield layer composed of a metal conductor and arranged around the binder layer, and a sheath covering around the shield layer. An outer diameter of the sheath is 2.0 mm or less. An amount of the metal conductor per unit length used in the shield layer is 0.4 times or more and 0.7 times or less than an amount of the metal conductor per unit length used in the plural wires.

An electric wire includes a flat stranded conductor having a flat shape in cross sectional view and configured by a plurality of conductive wires each having a wire diameter of 1.2 mm or less and which are stranded to each other, and a flat covering portion that is an insulator and covers the flat stranded conductor. The flat covering portion has a uniform elongation of 43.5% or more.
