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. 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 ...

4. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Outdoor applications may require the jacket to resist ultraviolet light, oxidation, rodent damage, or direct burial. Flooded coaxial cables use a water-blocking gel to protect the cable from water infiltration through minor cuts in the jacket. For internal chassis connections the insulating jacket may be omitted. [examples needed]

5. Underground power line - Wikipedia

   en.wikipedia.org/wiki/Underground_power_line

   Underground cables need a narrower surrounding strip of about 1–10 meters to install (up to 30 m for 400 kV cables during construction), whereas an overhead line requires a surrounding strip of about 20–200 meters wide to be kept permanently clear for safety, maintenance, and repair.

6. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   This is similar to the preceding, but rated for dry or wet environments and conductor temperatures up to 75 °C (167 °F), [18] and is commonly used in subsurface conduits which may fill with water. A great deal of THWN wire is actually dual-rated, and meets THHN the specification as well, so may be used in wet environments up to 75°C or dry ...

7. 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.
