Fdn Galvanized Stockbridge Vibration Damper Electrical Power Fitting
Product Overview
This FDN Type Vibration Damper (also called vibration absorber, wind damper, power line damper) is a high-performance power fitting specially designed for overhead transmission lines, distribution lines and ADSS/OPGW optical cable systems. It adopts advanced casting technology, which is the core solution to suppress wind-induced vibration of conductors and cables, effectively preventing fatigue damage, strand breakage and cable failure at suspension points, ensuring the long-term safe and stable operation of power grids and communication lines.

Product Features
- 1. Efficient Vibration Damping Performance
- With classic Stockbridge dual-weight design and high-quality cast hammer heads, it generates reverse vibration to offset wind-induced energy. It effectively reduces conductor vibration amplitude, eliminates stress concentration, and suppresses wind galloping and aeolian vibration for longer line service life.
- 2. Wide Compatibility & Easy Installation
- It is compatible with various conductors (ACSR, AAC, AAAC) and ADSS/OPGW optical cables. The bolted clamp allows quick, tool-free installation, saving time and labor, with anti-slip design for enhanced stability.
