Vibration Damper

It can restrain the Aeolian vibration and wave of the optic fibre cable.
Product process

Vibration Damper for electric power cable is divided into two types, including spiral vibration damper and 4D vibration damper.

 

Installation quantity, installation site and installation distance of vibration damper under each span length should be confirmed in according to the line circumstance.

Spiral Vibration Damper

Spiral Vibration Damper is made of engineering plastic which is high strength, aging resistance and high elastic; it will not cause any mechanical damage to the optical fibre cable. 


Spiral Vibration Damper is widely used in ADSS cable installation. Each Spiral Vibration Damper is composed of a short part of grip section and a long vibration attenuation section. The grip section can effectively close upon the cable to make sure the spiral vibration damper is firmly fixed on the cable; the vibration attenuation section create damping effect through mutual crash with the cable, to consume the cable vibration energy, so that the Aeolian vibration on the cable can be weaken. 

 

 

4D Vibration Damper and Armor Rod

4D Vibration damper is composed of two different weight hammers stranded galvanized steel wire with high elasticity and high-intensity, and aluminum alloy clamp.


The 4D series Vibration dampers we provided are Stockbridge Tuning Fork, with four resonant frequencies, the frequency range is from 3Hz to 150Hz. With wide frequency range, the 4D vibration damper can highly consume vibration energy, and effectively dissipate the energy caused by cable Aeolian vibration, reduce cable vibration horizontal, extend the cable service life. 


Vibration Damper can be installed on both OPGW and ADSS cable. Armor rods are needed when it is installed on OPGW and ADSS cable. 


Armor rods are also called Vibration damper protective rods. Because of the concentrated stress, vibration damper will cause some damages to the cable. The armor rods provide proper stress distribution on the optical cable and protect the cable.

 

 

Non-slip type Vibration Damper with armor rods

Non-slip type vibration damper is composed of hammer and helical clip. It can reduce the breeze fatigue damage of wire and optical cable. But if the vibration damper produce the slip it will cause greater damage to the wire, so must be ensure to installed with reasonable weight and position.


The non-slip type vibration damper we provided with particular weight and reasonable shape design ,it can produce multi resonant frequencies and effective absorption the different frequencies of vibration. Adopting the helical structure form of installation, it have large adhesion area and evenly distributed the Adhesion force, without stress concentration, can keep the constant installation moment of force, ensure the products don't have any slip phenomenon, effectively prevent the fatigue damage of cable, extension the wire service life.
