Amortisseur de vibration

Le damper de vibration de la série 4D est un raccord de réduction des vibrations dédié aux câbles optiques. Adoptant un design de bloc de poids différentiel avec des poids grands et petits, il protège les câbles contre les dommages causés par la fatigue induite par les vibrations. Il présente un fonctionnement stable et une compatibilité avec une large gamme de spécifications de câbles.

Introduction du Produit :

The 4D-series vibration damper mainly consists of three components: aluminium alloy clamp, high-tensile galvanized-steel messenger cable and galvanized cast-iron weights. The weights are bonded to the messenger cable by glue. Featuring four resonant frequencies, the product operates across a frequency range of 6 Hz – 120 Hz, delivering a much broader effective damping bandwidth compared with conventional Stockbridge dampers.

Core Advantages：

Broad-frequency Vibration Damping: Equipped with four resonant frequencies and an operating frequency range of 6 ‑120 Hz, it provides a far wider effective damping bandwidth than ordinary vibration dampers. It achieves outstanding damping performance and extends the service life of cables and fittings.
Reliable Connection: Weights are bonded to the messenger cable by glue, delivering firm connection and excellent anti-fatigue performance.
Corrosion-resistant Materials: Key components are made of aluminium alloy and galvanized steel, suitable for complex service conditions of outdoor transmission lines.
