4D Series Vibration Dampers

1. The weights of 4D series damper are different, small one and large one. This type damper has 4 resonant frequencies from 6HZ to 120HZ, allowing the dampers to be effective across a much wider frequency range than standard Stockbridge dampers.
2. Connection weights with messenger cable by glue, offering better damper effectiveness and working life.
3. The 4D series dampers are suitable for use on all conductor and earth wire constructions including ACSR, AAC, AAAC and galvanized steel wire, aluminum-clad steel wire with covering the range of sizes from 7.5mm to 34mm.

Spiral Vibration Dampers

1. Effectively reduces levels of Aeolian vibration on cables.
2. Has a helically formed dampening section sized for interplay of damper and cable, to provide the action/reaction motion that opposes the natural vibration wave. A smaller gripping section gently grips the cable so that cable and fiber are not damaged or distorted and there is no optical signal loss.
3. ADSS cables tend to vibrate at higher levels than other cables of comparable size, mainly due to their relatively lighter weight. Also the soft nature of their jackets and internal construction requires special consideration.
