The sag in an overhead transmission line is given by:
where, S = Sag
W = Weight per unit length of the conductors
L = Length of span
T = Tension of the conductor
Explanation
Sag is proportional to the square of the length of the conductor span.
S α (1/T)
So, If supports are at equal levels and tension in an overhead line is increased to two times, then sag decreases to half of the previous value.
