ممتص الاهتزاز

يعتبر المثبط الاهتزازي من سلسلة 4D موصل اهتزازي مخصص لكابلات الألياف الضوئية. يعتمد تصميم كتلة وزن تفاضلية مع أوزان كبيرة وصغيرة، ويحمي الكابلات من أضرار التعب الناتجة عن الاهتزاز. يتميز بعملية مستقرة وتوافق مع مجموعة واسعة من مواصفات الكابلات.

مقدمة المنتج:

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.
