In the sag formula, what does 'T' represent?

The sag formula is an important aspect of overhead line design, particularly for power distribution. In that context, the variable 'T' specifically represents tension. When calculating the sag of a cable or conductor, there are various forces acting on the line, including weight and tension. Tension is crucial as it helps determine how much sag a cable will have under its own weight and any additional loads.

Understanding 'T' as tension allows for the application of the sag equation, which is essential for ensuring that conductors are installed with the appropriate sag to avoid issues like excessive stress on cables, potential short circuits, or clearance issues with the ground or structures.
