Overhead power line - Wikipedia
An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles.
Electric power transmission - Wikipedia
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a transmission network.

Transmission Lines: Types, Function & Grid Infrastructure
Transmission lines are crucial in delivering electric power from generating stations to consumers. These vital power system components ensure that electrical energy reaches homes, businesses, and industries efficiently and safely.
The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites, etc.) via lower voltage lines.
