The purpose of installing protective hardware in overhead transmission lines

The purpose of installing protective hardware in overhead transmission lines :


1) due to the wind action of overhead transmission lines and lightning arresters, the periodic oscillating in the vertical plane will be caused, and a series of standing waves with small amplitude are formed at the whole span.


2) if the wire vibrate for a long time, additional mechanical stress will be generated, which will cause fatigue fracture of the conductor along with the passage of time.


3) periodic vibration may also cause the steel foot to loose and fall off, the fittings wear and tear, and even destroy the tower.
