  2. Direct-buried cable - Wikipedia

    en.wikipedia.org/wiki/Direct-buried_cable

    Cross-section of 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 ...

  3. Underground pneumatic boring - Wikipedia

    en.wikipedia.org/wiki/Underground_pneumatic_boring

    The valve reopens, and the cycle repeats. The friction between the tool and the earth keeps the tool from sliding back. Tool speed is controlled by manipulating the air supply to the tool. This air supply valve is outside the tool and remains accessible to the operator. As the tool pounds through the ground, it compresses the soil.

  7. Underground power line - Wikipedia

    en.wikipedia.org/wiki/Underground_power_line

    Underground cable locations are not always obvious, which can lead to unwary diggers damaging cables or being electrocuted. Operations are more difficult since underground cables' high reactive power produces large charging currents, making voltage control more difficult. Large charging currents arise due to the higher capacitance from ...

  8. Outside plant - Wikipedia

    en.wikipedia.org/wiki/Outside_plant

    Outside plant cabling, whether copper or fiber, is generally installed as aerial cable between poles, in an underground conduit system, or by direct burial. [2] Hardware associated with the outside plant must be either protected from the elements (for example, distribution frames are generally protected by a street side cabinet) or constructed ...

  9. Power cable - Wikipedia

    en.wikipedia.org/wiki/Power_cable

    A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power . Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
