275kV overhead line is a vital part of the extra-high voltage (EHV) transmission network. Its primary purpose is to efficiently transport large blocks of power from major power generation sites (like power plants or wind farms) to regional substations. By operating at such a high voltage, power can be transmitted over hundreds of kilometers with minimal energy loss. This is the "superhighway" of the electrical grid, connecting the generation network to the distribution network that serves our cities and towns.
