2. Transmission tower - Wikipedia

   en.wikipedia.org/wiki/Transmission_tower

   A transmission tower (also electricity pylon, hydro tower, or pylon) is a tall structure, usually a lattice tower made of steel that is used to support an overhead power line. In electrical grids, transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from ...

3. Insulator (electricity) - Wikipedia

   en.wikipedia.org/wiki/Insulator_(electricity)

   t. e. Ceramic insulator used on an electrified railway. Three-core copper wire power cable, each core with an individual colour-coded insulating sheath, all contained within an outer protective sheath. An electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons ...

4. All-dielectric self-supporting cable - Wikipedia

   en.wikipedia.org/wiki/All-dielectric_self...

   All-dielectric self-supporting (ADSS) cable is a type of optical fiber cable that is strong enough to support itself between structures without using conductive metal elements. It is used by electrical utility companies as a communications medium, installed along existing overhead transmission lines and often sharing the same support structures ...

5. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   Earthing systems. v. t. e. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [ 1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.

6. Substation - Wikipedia

   en.wikipedia.org/wiki/Substation

   A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

7. History of Poles in the United States - Wikipedia

   en.wikipedia.org/wiki/History_of_Poles_in_the...

   Poles had even higher crop yields than the local Americans because of their labor-intensive efforts and willingness to try lands previously disregarded as worthless. Poles succeeded rapidly; in Northampton in 1905, Poles were 4.9% of the population and owned 5.2% of the farmland. By 1930, they made up 7.1% of the town and owned 89.2% of the ...
