  2. Bus duct - Wikipedia

    en.wikipedia.org/wiki/Bus_duct

    In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal [1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity. It is an alternative means of conducting electricity to power cables or cable bus.

  3. Feedthrough - Wikipedia

    en.wikipedia.org/wiki/Feedthrough

    A feedthrough is a conductor used to carry a signal through an enclosure or printed circuit board. Like any conductor, it has a small amount of capacitance . A "feedthrough capacitor" has a guaranteed minimum value of shunt capacitance [ clarify ] built in it and is used for bypass purposes in ultra-high-frequency applications. [ 1 ]

  4. Busbar - Wikipedia

    en.wikipedia.org/wiki/Busbar

    The busbar's material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but electrical substations may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars.

  5. Aluminium-conductor steel-reinforced cable - Wikipedia

    en.wikipedia.org/wiki/Aluminium-conductor_steel...

    Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.

  6. Drill pipe - Wikipedia

    en.wikipedia.org/wiki/Drill_pipe

    Standard max upset dimensions are specified in API 5DP, but the exact dimensions of the upset are proprietary to the manufacturer. After upsetting, the tube then goes through a heat treating process. Drill pipe steel is commonly quenched and tempered to achieve high yield strengths (135 ksi is a common tube yield strength).

  7. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    The current density inside round wire away from the influences of other fields, as function of distance from the axis is given by: [6]: 38 Current density in round wire for various skin depths. Numbers shown on each curve are the ratio of skin depth to wire radius. The curve shown with the infinity sign is the zero frequency (DC) case.
