Abstract :
A simple and accurate method is described for compiling stringing charts for overhead transmission lines, for either horizontal or inclined spans. All calculations can be carried out with a 20 inch slide rule, and no tables of functions are required other than those included in this paper. The procedure is the same for horizontal and for oblique spans. Moreover, no. loss of accuracy is suffered as the inclination of the span is increased. The final result is obtained by means of a graphical solution which, in principle, is based upon the Thomas chart.
