  2. Earthing system - Wikipedia

    en.wikipedia.org/wiki/Earthing_system

    Grounding connectors. Connectors for earthing installation are a means of communication between the various components of the earthing and lightning protection installations (earthing rods, earthing conductors, current leads, busbars, etc.). For high voltage installations, exothermic welding is used for underground connections.

  3. RG-6 - Wikipedia

    en.wikipedia.org/wiki/RG-6

    The number was assigned sequentially. The RG unit indicator is no longer part of the JETDS system (MIL-STD-196E) and cable sold today under the RG-6 label is unlikely to meet military specifications. In practice, the term RG-6 is generally used to refer to coaxial cables with an 18 AWG (1.024 mm) center conductor and 75 ohm characteristic ...

  4. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    RG-62 is a 93 Ω coaxial cable originally used in mainframe computer networks in the 1970s and early 1980s (it was the cable used to connect IBM 3270 terminals to IBM 3274/3174 terminal cluster controllers). Later, some manufacturers of LAN equipment, such as Datapoint for ARCNET, adopted RG-62 as their coaxial cable standard. The cable has the ...

  5. F connector - Wikipedia

    en.wikipedia.org/wiki/F_connector

    The F connector is an inexpensive, gendered, threaded, compression connector for radio frequency signals. It has good 75 Ω impedance match for frequencies well over 1 GHz [2] and has usable bandwidth up to several GHz. Connectors mate using a 3/8-32UNEF thread. The female connector has a socket for the center conductor and external threads.

  6. Ground and neutral - Wikipedia

    en.wikipedia.org/wiki/Ground_and_neutral

    A ground connection that is missing or of inadequate capacity may not provide the protective functions as intended during a fault in the connected equipment. Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage.

  7. Electrical termination - Wikipedia

    en.wikipedia.org/wiki/Electrical_termination

    A terminating resistor for a television coaxial cable is often in the form of a cap, threaded to screw onto an F connector. Antenna cables are sometimes used for internet connections; however, RG-6 should not be used for 10BASE2 (which should use RG-58) as the impedance mismatch can cause phasing problems with the baseband signal.

  8. Electrode line - Wikipedia

    en.wikipedia.org/wiki/Electrode_line

    Many long-distance HVDC systems use sea or ground return for the DC neutral current since this is considerably cheaper than providing a dedicated metallic return conductor on an overhead wire or cable. The ground electrode is separated from the converter station so that current returning through the ground electrode does not cause corrosion of ...

  9. MIL-DTL-5015 - Wikipedia

    en.wikipedia.org/wiki/MIL-DTL-5015

    MIL-DTL-5015 is a United States Military Standard which covers heavy-duty circular electrical connectors with soldered or crimped contacts. [1] They are used for both digital and analog signals, as well as power distribution, and are common in various fields, including defense, aerospace, and industrial machinery. [2]
