在中等风速（约5英里/小时）下，最常遇到由横向风作用引起的输电线路振动现象。并且其特征在于相当高的频率（每秒5到15个周期）。和小振幅（直到几个电缆直径）。这种类型的振动是由在金属丝后面形成的“卡门”涡流引起的，这是很容易理解的。
PHENOMENA of vibration in transmission lines due to the action of a transverse wind are encountered most frequently at moderate wind velocities (about 5 miles per hr.) and are characterized by rather high frequencies (5 to 15 cycles per sec.) and small amplitudes (up to a few cable diameters). This type of vibration is caused by the “Karman” vortices forming behind the wire and is well understood.
