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. RG-6 - Wikipedia

   en.wikipedia.org/wiki/RG-6

   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 impedance .

   One may also be referred to as a services tunnel, services trench, services vault, or cable vault. Smaller cable containment is often referred to as a cable duct or underground conduit . Direct-buried cable is a major alternative to ducts or tunnels.

5. Power cable - Wikipedia

   en.wikipedia.org/wiki/Power_cable

   Cables intended for direct burial must consider damage from backfill or dig-ins. HDPE or polypropylene jackets are common for this use. Cables intended for subway (underground vaults) may consider oil, fire resistance, or low smoke as a priority. Few cables these days still employ an overall lead sheath.

6. Teck cable - Wikipedia

   en.wikipedia.org/wiki/Teck_cable

   Teck cables in industrial installation. Teck cable is a very versatile power cable because it may be used where subject to limited mechanical damage, it is resistant to water, petrochemicals, and sunlight. It may be used for direct-earth burial and if properly sealed at the connection point, in explosive atmospheres such as gasoline dispensing ...

7. 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.
