   A utility pole, commonly referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and ...

3. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   Rural distribution is mostly above ground with utility poles, and suburban distribution is a mix. [1] Closer to the customer, a distribution transformer steps the primary distribution power down to a low-voltage secondary circuit, usually 120/240 V in the US for residential customers.

4. Pothead - Wikipedia

   en.wikipedia.org/wiki/Pothead

   A three phase electric circuit terminated with a pothead Crossarms with two three phase electric circuits terminated with potheads. A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers. [1]

5. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   Power lines and supporting structures can be a form of visual pollution. In some cases the lines are buried to avoid this, but this "undergrounding" is more expensive and therefore not common. For a single wood utility pole structure, a pole is placed in the ground, then three crossarms extend from this, either staggered or all to one side. The ...

6. Transmission tower - Wikipedia

   en.wikipedia.org/wiki/Transmission_tower

   Transmission tower in Toronto, ON Single-circuit three-phase transmission line Transmission towers on a hill field. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines.

7. Service drop - Wikipedia

   en.wikipedia.org/wiki/Service_drop

   In electric power distribution, a service drop is an overhead electrical line running from a utility pole, to a customer's building or other premises. It is the point where electric utilities provide power to their customers. [1] The customer connection to an underground distribution system is usually called a "service lateral".
