what is the purpose of transmission towers in electrical grids?

the primary purpose of transmission towers in electrical grids is to support and carry high-voltage overhead power lines that transmit bulk electric power over long distances. specifically, transmission towers serve the following key functions:

support overhead conductors/power lines: transmission towers provide the structural support needed to keep the heavy high-voltage conductors (wires) elevated and suspended at a safe height above the ground. this allows power to be transmitted efficiently over long distances.

maintain clearances: the towers are designed to maintain minimum safe clearances between the energized conductors and the ground, buildings, vegetation, etc. proper clearances prevent electrical discharges and ensure public safety.

span obstacles: transmission towers allow power lines to span over obstacles like rivers, roads, railways by providing the required height clearance.

carry ground wires: many transmission towers also carry overhead ground wires or shield wires at the top, which protect the power lines from direct lightning strikes by providing a conductive path to ground.

facilitate grid interconnections: transmission towers and lines interconnect power plants, substations, and regional grids, enabling the transmission of electricity over long distances and facilitating the integration of diverse energy sources.

accommodate fiber optic cables: some transmission towers also carry fiber optic cables for communication and monitoring purposes, optimizing the infrastructure.

all in all, transmission towers are critical components of the electrical grid, designed to reliably and safely support the overhead high-voltage conductors that transmit bulk electric power from generation sources to substations and distribution networks over long distances.
