Spiral Vibration Dampers

 

SVD Series Spiral Vibration Dampers are designed to eliminate the damage caused by Aeolian vibration and reduce overall vibration on bare cables. Made of weather-resistant, non-corrosive plastic, these dampers have a large, helically-formed damping section sized for the cable. A smaller gripping section gently grips the cable. Each damper is marked with the conductor range and color coded to indicate the cable diameter size range. Line design, temperature, tension, wind flow exposure and history of vibration on similar construction in the location are factors to consider when determining the amount of protection required. Installation can be on both sides of the support location—at least one hand-width from the ends of Armor Rods or cable hardware.

DESCRIPTION

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 theaction/reaction motion that opposes the natural vibration wave.

3.A smaller gripping section gently grips the cable so that cable and fiber are not damaged ordistorted and there is no optical signal loss.

4.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.

5.The degree of protection needed for a specific application depends on a number of factors suchas cable type, line design temperature, tension, and exposure to wind flow.
