What is Sag “is sag a necessity or evil” Discuss. The straight distance between the two poles gives the shortest distance. Therefore to minimize the length of conductor, one may stretch the conductor to make it straight. However if the conductor is stretched too much, beyond its safe value, then conductor may break due to … Read more
Span Lengths of Electrical Transmission Line The distance between the two adjacent poles is known as span length. It is generally denoted by ‘l’ (L) and specified in meters. The location of the supports (towers) depends upon the profile of the land along which transmission line is to be run. This means the span length … Read more
