2. Overhead line - Wikipedia

   en.wikipedia.org/wiki/Overhead_line

   Overhead lines, like most electrified systems, require a greater capital expenditure when building the system than an equivalent non-electric system. While a unelectrified railway line requires only the grade, ballast, ties and rails, an overhead system also requires a complex system of support structures, lines, insulators, power-control ...

3. Overhead power line - Wikipedia

   en.wikipedia.org/wiki/Overhead_power_line

   Low voltage overhead lines may use either bare conductors carried on glass or ceramic insulators or an aerial bundled cable system. The number of conductors may be anywhere between two (most likely a phase and neutral) up to as many as six (three phase conductors, separate neutral and earth plus street lighting supplied by a common switch); a ...

   A pair of shoes can be seen hanging from the wires (center-left, far right) A utility pole is a column or post, usually made out of wood or aluminum alloy, [ 1 ] 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 street lights.

6. 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 ...

7. All-dielectric self-supporting cable - Wikipedia

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

   All-dielectric self-supporting cable. 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 ...
