Sag refers to the downward dip of the conductor between two support poles, while tension is the pulling force on the conductor. Calculating both is critical for:

• Safety: It ensures that the conductor maintains safe clearances from the ground and other objects, especially under varying weather conditions (e.g., high temperatures causing sag, or ice/wind loads increasing tension).

• Structural Integrity: It prevents excessive tension that could stress and potentially damage poles and fittings.

• Cost and Efficiency: Proper sag and tension ensure the correct amount of conductor is used, avoiding unnecessary costs and potential line failures.

We provide a wide range of tension stringing equipment designed for the precise control of sag and tension during installation, which is vital for the long-term reliability of a 33kV line.
