Large power line towers, also known as high-voltage transmission towers, are critical infrastructure components designed to transport electricity over long distances from power plants to local distribution networks. These towers are engineered to handle much higher voltages than the distribution towers, often carrying tens of thousands to hundreds of thousands of volts. Their design and construction are pivotal for ensuring the efficiency and security of the power transmission system.
