Product Description

What's Vibration damper? 
Vibration dampers are usually used in high voltage and extra-high voltage electrical energy overhead transmission lines to handle aeolian and galloping or dancing vibrations in the transmission lines' conductors. The dampers are designed in such a way that they attenuate the line vibrations by reaching the same frequency as the cable that has wind-induced vibrations.
 

Vibration damper for OPGW&ADSS Specification 

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 hyperactive rods Because of the concentrated stress,vibrationdamper will cause some damages to cable. the armor rods not only provide proper stress distribution on the optical cable but also protect cable well. 

    

 

For OPGW vibration damper, Here we introduce our 4D Vibration damper which is composed with two different weight hammers stranded galvanization steel wire with high elasticity and high-intensity, and aluminum alloy clamp. the product specificaiton as below: 

 

 

The 4D Vibration dampers we provided are Stock-bridge 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.

We can supply more other type vibration dampers. eg: DB type. FD/FG type and FD-L type,FDZ type etc which aren't listed, please contact us for your requirement. we always here with you. now just do it.
