Answer 1

Stringing chart

The stringing chart gives the data per sag to be allowed and the tension to be allowed in a transmission line for a particular temperature.
The stringing chart represents a graph of sag and tension vs temperature.
The stringing chart is prepared by calculating the sag and tension on the conductor under the worst conditions such as maximum wind pressure and minimum temperature by assuming a suitable safety factor.
As we want low Tension and minimum sag in our conductor but that is not possible as sag is inversely proportional to tension.
It is because low sag means a tight wire and high tension whereas low tension means a loose wire and increased sag.
Therefore, we make a compromise between the two but if the case of temperature is considered and we draw a graph then that graph is called a Stringing chart.
