In an electrical construction, grounding refers to a work for connecting a part of an electrical circuit or electrical equipment to the ground using a conductor.

Since the ground maintains approximately the same potential, circuit parts connected to the ground through a low-resistance conductor may be considered to have a uniform potential value, and a conductor connecting an electric device to the ground is called a grounding conductor or grounding wire.

The grounding wire is used with an insulating coating formed on the wire for the purpose of safety in processing. In the underground, the grounding wire is used in the form of a bare wire without the insulation coating for the purpose of close contact with the ground. The grounding wire can be used as a single wire when the size is small, however, if the size becomes large, several strands of wires are twisted and used in the form of a stranded wire.

A conventional grounding wire installed in the ground is composed of a single stranded wire, so an inner surface of the stranded wire does not come into contact with the ground, so it is difficult to lower the grounding resistance value.

Therefore, there are provided a flat array grounding wire and a grounding method using the same, in which the flat array grounding wire is configured to lower the grounding resistance value by greatly increasing the surface area in contact with the ground by arranging the grounding wires used for a grounding work in an electrical construction on a flat plane, so that the construction cost can be reduced as the grounding resistance value is lowered.

A wiring member includes: a wire-like transmission member including a transmission wire body and a covering for covering the transmission wire body; a sheet material to which the wire-like transmission member is fixed; and a cover formed of a material different from a material of the covering, covering the wire-like transmission member from a side opposite to the sheet material, and fixed to the sheet material, wherein the sheet material includes a first fixing part to which the covering is directly fixed and a second fixing part which is directly fixed to the cover more easily than the first fixing part and to which the cover is directly fixed.

The wire harness 11 disclosed by the present specification includes: a sheet-shaped base member 12; and a plurality of covered electric wires W fixed side by side along the base member 12, in which the transverse cross-sectional area of at least one of the plurality of covered electric wires W is different from the transverse cross-sectional area of another covered electric wire W, and the thickness of the covered electric wire W is substantially the same as the thickness of the covered electric wire W adjacent thereto.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.

A high-speed transmission cable and a cable end connector including the same are provided. The cable end connector includes a connector body and the high-speed transmission cable that includes at least one cable assembly, at least one transmission line, and an insulating material. The at least one cable assembly includes multiple ground wires and multiple differential pairs that are arranged at fixed intervals and in parallel with each other, an insulating layer, and at least one shielding layer. Each of the differential pairs includes two signal wires that are adjacently arranged, and is located between two adjacent ones of the ground wires. The insulating layer covers the ground wires and the differential pairs. The at least one shielding layer is located at an outer side of the insulating layer. The insulating material covers the at least one cable assembly and the at least one transmission line.

A cable includes an insulating part and one or more conducting parts disposed inside the insulating part. The insulating part includes a polymer resin layer with a product of shrinkage ratios C.sub.MD*TD, which is expressed as a product of a longitudinal shrinkage ratio and a transverse shrinkage ratio, of less than 0.24.

The present disclosure relates to a glueless repeatable finger attachment apparatus and method of monitoring a fuel cell voltage comprising the same.

An adapting cable structure includes a cable, a first circuit board and a second circuit board. The cable is used to transfer a power signal or a control signal. The first circuit board includes a plurality of contacting parts and a plurality of first welding parts. Another end of the cable is on the second circuit board and the plurality of the contacting parts are located at two sides of the first circuit board. The plurality of welding parts are connected to one end of the cable. Furthermore, a pattern of a text or a specific design is placed on the cable. The pattern is used to improve the appearance or the identification of the cable.

A flat electrical cable comprises a conductive core having a core sheath and a cooling channel having a cooling channel sheath. The cooling channel and the core extend mutually parallel to one another along a length of the cable and are integrally joined to one another by a web extending along the core and the cooling channel.
