Abstract:
This paper looks into the factors affecting sag in conductors while erecting an overhead line, it is very important that conductors are under safe tension. If the conductors are too much stretched between supports, the stress in the conductor may reach unsafe value and in certain cases the conductors may break due to excessive tension. The conductor sag should be kept to a minimum in order to reduce the conductor material required and to avoid extra pole height for sufficient clearance above ground level. It is also desirable that tension in the conductor should be low to avoid the mechanical failure of conductor and to permit the use of less strong supports. The effects of sag on electrical construction were examined. Also, a look into the solution to effect of sag were examined. The meaning sag was not left out. This write up suggested ways to reduce the effect of sag on overhead line conductors.

Keywords: conductor, electrical, line, over head, tension, transmission, sag.
