The global shift toward renewable energy requires a more robust and flexible grid. To meet this demand, modern overhead transmission lines are being constructed with a focus on increasing capacity, efficiency, and reliability. This includes the use of high-temperature low-sag (HTLS) conductors, which allow for higher power transfer without requiring new towers or significant structural modifications. We also see a growing trend in using advanced monitoring systems, often integrating with smart grid infrastructure, that provide real-time data on line conditions, enabling more efficient power distribution and reducing losses.
