Product Description

Specification

Product Description:
The Fd Vibration Damper (also known as Conductor Shock Absorber) is an essential power line accessory designed to mitigate aeolian vibrations, galloping oscillations, and wind-induced fatigue in overhead transmission conductors and optical ground wires (OPGW).

Engineered with high-damping rubber cores and hot-dip galvanized steel weights, it effectively dissipates vibrational energy (3Hz–150Hz) to prevent conductor damage and prolong cable lifespan. Suitable for HVAC/HVDC lines (33kV–1000kV), railway catenary systems, and fiber optic cables.

 
Key Features:

- Dual-Function Design – Controls vibrations + micro-shocks for conductors & OPGW

- Multi-Material Options – HDG steel / stainless steel / aluminum alloy

- Wide Compatibility – Fits conductors 8mm–50mm (custom sizes available)

- Standards Compliance – IEC 61897, IEEE 524, EN 50388

- Zero-Maintenance – Weather-resistant for 30+ years

Applications:

- Transmission lines (132kV–1000kV)
- OPGW/ADSS optical cable protection
- High-speed rail catenary systems
- Offshore wind farm power cables
