The non-resonant dynamic galloping of an iced, electrical transmission line is studied. Conditions and trends for the initiation of galloping have been given previously. Boundaries are presented here at which a periodic plunge or torsional motion loses stability and bifurcates into a quasi-periodic (mixed-mode) motion. Specific attention is given to the overall effects of an iced line's eccentricity and its inertia to mass ratio. These effects are shown to be more complicated than those for the corresponding co-centric line. [References: 5]
