ON THE REDUCTION OF WIND LOADING ON OVERHEAD TRANSMISSION LINE

(1981)

Abstract

The reduction of wind loading on the transmission line conductor is a major design factor from the standpoint of economical construction. To realize this reduction, the authors investigated the surface drag coefficient of various kinds of conductor models, by means of wind tunnel experiments, and have succeeded in obtaining some empirical formulae. And using these formulae, we have developed special surface configuration which gives a 40% reduction in drag coefficient, compared to that of ordinary conductors, at the maximum wind velocity used for the design of overhead lines in Japan.
