Installation Position Of The Screw Anti-vibration Device On The Overhead Line

Installation position of the screw anti-vibration device on the overhead line

How much do you know about the screw anti-vibration device? The screw anti-vibration device, also known as the anti-vibration whip, is used in the overhead line installation and use, often applied to ADSS optical cable, is the use of its anti-vibration part to produce damping effect on wind vibration, consumption and weaken the energy of optical cable vibration, so as to protect the optical cable. So where is the screw shock absorber installed on the overhead line?

The spiral shock absorber is composed of a shorter gripping section and a longer damping section. The role of the gripping section is to effectively grip the optical cable, so that the spiral anti-vibration whip is firmly fixed on the cable, and the damping section is to consume the optical cable vibration energy, so that the breeze vibration on the optical cable is weakened. Hearing this, will everyone think that this is not the reason for hanging the shock hammer on the high voltage overhead line? Is it the same? Anti-vibration hammer and anti-vibration whip must not be the same, first from the

appearance can be seen that one is a spiral PVC round rod and the other is two small hammers, in addition, the anti-vibration hammer is the use of the inertia of the hammer head, so that its steel strand produces internal friction consumption of overhead line vibration energy, The spiral shock absorber is a kind of device that dissipates the vibration energy through the impact with the cable, so as to eliminate or reduce the vibration generated by the laminar wind when the cable is

running.

The screw shock absorber is installed on the tensioning clip or the overhang clip above, ADSS cable below 100 meters span do not consider, 200 meters span set up tensioning clip, one side of the overhang clip. Use two on each side for 300 meter span erection. Three cables are used on the side of the 400-meter span, and the cable anti-shock hammer is configured on the side of the 500-meter span. The screw shock absorber is easy to install, and the wear degree of the wire is very small, and the use of the screw shock absorber is non-metallic material with very good corrosion resistance.
