导线振动是指导线的周期性运动。根据频率和振幅的不同，导线的振动大致可分为3种：高频微幅的微风振动、中频中幅的次档距振动和低频大振幅的舞动。3种振动都会给导线和输电线路造成破坏。
弯曲振动频率对导线微动寿命影响不大。
The frequency of bending vibration has less effect on the fretting life of conductor.
分析表明，断线的冲击荷载将对导线和输电塔均产生较大的动力放大效应，风荷载将加剧断线引起的振动。
The results show that the dynamic impact loads on broken wire cases will magnify response of the conductors and tower. Wind loads will aggravate the vibration caused by the sudden cable rupture.
最后，给出了输电塔体系纵向振动时考虑导线影响的界限，提出了输电塔-导线体系纵向振动的简化抗震计算方法。
At the end, the simplified method of aseismic calculation is presented for the in_plane vibration of the transmission tower_lines system.
