2. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   Overhead lines or overhead wires are used to transmit electrical energy to trams, trolleybuses or trains. Overhead line is designed on the principle of one or more overhead wires situated over rail tracks. Feeder stations at regular intervals along the overhead line supply power from the high-voltage grid.

3. Jump wire - Wikipedia

   en.wikipedia.org/wiki/Jump_wire

   Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...

4. Jump start (vehicle) - Wikipedia

   en.wikipedia.org/wiki/Jump_start_(vehicle)

   Jump starting a vehicle. Crocodile clips, also called automotive clips, on a set of jumper cables. A jump start, also called a boost, is a procedure of starting a motor vehicle (most commonly cars or trucks) that has a discharged battery. A temporary connection is made to the battery of another vehicle, or to some other external power source.

5. Wire gauge - Wikipedia

   en.wikipedia.org/wiki/Wire_gauge

   In commerce, the sizes of wire are estimated by devices, also called gauges, which consist of plates of circular or oblong form having notches of different widths around their edges to receive wire and sheet metals of different thicknesses. Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to ...

6. High-voltage cable - Wikipedia

   en.wikipedia.org/wiki/High-voltage_cable

   A high-voltage cable (HV cable), sometimes called a high-tension cable (HT cable), is a cable used for electric power transmission at high voltage. A cable includes a conductor and insulation. Cables are considered to be fully insulated. This means that they have a fully rated insulation system that will consist of insulation, semi-con layers ...

7. Third rail - Wikipedia

   en.wikipedia.org/wiki/Third_rail

   Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") for the purpose. On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used.

9. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈkoʊ.æks /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. The term coaxial refers to the inner conductor and the ...
