  2. Underground power line - Wikipedia

    en.wikipedia.org/wiki/Underground_power_line

    An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...

  4. Electrical conduit - Wikipedia

    en.wikipedia.org/wiki/Electrical_conduit

    An electrical conduit is a tube used to protect and route electrical wiring in a building or structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes. Conduit is generally installed by electricians at the site of installation of electrical equipment.

  5. Direct-buried cable - Wikipedia

    en.wikipedia.org/wiki/Direct-buried_cable

    Direct-buried cable (DBC) is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any other cover, sheath, or duct to protect it. [1] Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil acidity.

  6. Electrical wiring - Wikipedia

    Electrical panels, cables and firestops in an electrical service room at a paper mill in Ontario, Canada. Electrical panels are easily accessible junction boxes used to reroute and switch electrical services. The term is often used to refer to circuit breaker panels or fuseboxes. Local codes can specify physical clearance around the panels.

    Electric wiring. conduit - underground for line voltage, vulnerable locations, under or in constructed elements-pavements; cable, wire - underground per codes for line and low voltage, above ground at stake-mounted and tree mounted fixtures. Light fixtures - fixed location - line voltage (120 V U.S. or 240 V Europe) and low voltage (12 V U.S.) [2]

  8. Directional boring - Wikipedia

    en.wikipedia.org/wiki/Directional_boring

    Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant ...

  9. Armoured cable - Wikipedia

    en.wikipedia.org/wiki/Armoured_cable

    In electrical power distribution, armoured cable usually means steel wire armoured cable (SWA) which is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11 kV Cable and 33 kV Cable – and is found in underground systems, power networks and cable ducting.
