The sag in a transmission line conductors depends on several factors. These factors are discussed below:

Conductor Material:
The material used in the construction of the conductor affects its sag. Conductors made up of different materials have different thermal expansion coefficients, which result in varying amounts of sag. For instance, aluminum conductors have higher thermal expansion coefficients than steel conductors. Therefore, they tend to sag more when exposed to high temperatures.

Height of the Tower:
The height of the tower affects the sag of the conductor as it determines the span between two towers. The longer the span, the more the conductor sags. Therefore, taller towers can help reduce sag as they increase the height of the conductor above the ground.

The Tension in Conductors:
The tension in the conductor affects the sag as it determines the force acting on the conductor. The higher the tension, the less the sag. Therefore, increasing the tension in the conductor can help reduce sag.

Conclusion:
In conclusion, the sag in a transmission line conductor depends on several factors such as the conductor material, height of the tower, and the tension in conductors. A combination of these factors can be used to reduce sag and maintain the stability of the transmission line.
