"WebJan 19, 2024 · Sag is defined as the difference in level between points of supports and the lowest point on the conductor. Sag of conductor’s between two poles can be determined by \(S = \frac{{W{L^2}}}{{8T}}\) Where, S is the sag of conductors. W is the weight per unit length of the conductor. L is the length of span. T is the tension in the conductor " - Sag and tension of conductors
