English
- 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.
Vibration Damper (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.
