Vibration Damper & Armour Rod for OPGW / ADSS Cables

The TX Series Vibration Damper and Armour Rod by Telexc is engineered to protect overhead power and fiber optic cables from wind-induced vibration, fatigue, and mechanical damage. Designed for OPGW, ADSS, and conductor systems, the solution effectively suppresses aeolian vibration while evenly distributing stress along the cable surface.

Using a multi-resonance tuning fork principle, the TX vibration damper dissipates vibration energy across a wide frequency range. The accompanying armour rods provide additional reinforcement at clamp contact points, preventing abrasion, strand damage, and long-term fatigue.

Installation Guide

1. Select a damper model based on cable impedance and span length

2. Choose clamp diameter according to cable and protection rod size

3. Install dampers as per the vibration analysis scheme

4. Orient the hammer heads toward the tower

5. When required, install armour rods before damper mounting

6. Maintain a minimum 50 mm clearance from the rod ends
