A note on galloping conductors

The results of wind tunnel tests on a series of two-dimensional modela simulating circular cables with various ice formations are presented. The stability of small oscilla\uad tions of a transmission line in a steady wind normal to the \ub7 span is considered9 and the wind tunnel result.s are used to calculate the behaviour of a cable with D shaped fairings. The results of dynamic tests with an oscillating model show reasonable agreement with the theoretical predietions.Peer reviewed: NoNRC publication: Ye
