by Expert-6 answered Sep 27, 2024

Could you specify what aspect of power transmission lines you're most interested in? Are you looking for a general overview, their components, or perhaps their function in the electrical grid?

A power transmission line is a high-voltage electric line used to carry electricity over long distances from power plants to substations or distribution centers. These lines are designed to transmit large amounts of electrical energy efficiently, often at voltages ranging from tens of thousands to hundreds of thousands of volts. They can be overhead lines supported by towers or underground cables, and their design minimizes energy loss due to resistance while ensuring safety and reliability in delivering electricity to consumers.
