Sag is the vertical distance between the highest point of support and the lowest point on a suspended conductor. This "dip" in the conductor is a critical factor in the design and maintenance of overhead transmission lines. At Ningbo Changshi, we recognize that proper sag management is essential for ensuring safety and reliability. Without the right amount of sag, the conductor may experience excessive tension, leading to potential breakage or inadequate clearance from the ground, buildings, or other infrastructure.
