WebThe sag in overhead line is a length in between support point of conductor and the lowest point on the conductor of transmission and distribution overhead line. Calculation of Sag: The sag & tension of conductor may be calculated in the following condition:-. a) When the supports are at equal levels. b) When the supports are at unequal levels. WebA bent shape forms in the conductor due to the same two supports at the same level. In comparison to the conductor’s span, Sag is fairly small. The stress at the supports is almost equivalent to the tension in the conductor at any point. The Sag span curve has a Parabolic shape. Each conductor point’s stress always works tangentially.

WebSag. In many cases the reason designers wish to know the conductor sag is to understand the tension in the conductor. Sometimes conductor stringing tensions are supplied as mid-span sags since before the advent of LineSmarts sag was easier to measure than tension. As part of the tension calculation the sag is also calculated. WebThe final sag shape of conductors is used to select support point heights and span lengths so that the minimum clearances will be maintained over the life of the line. If the conductor is damaged or the initial sags are incorrect, the line clearances may be violated or the conductor may break during heavy ice or wind loadings.
