The spiral vibration damper is to dissipate the wind power input on the ADSS cable to prevent critical stress,it’s composed of a helical formed plastic rod. About one fifth of the overall length of the helix is of smaller diameter .This section is used to attach the damper and provides a completely reliable grip on the ADSS cable , the remaining section is for damping so that the helix has no close contact to the cable, its anti-vibration part to produce damping against wind vibration,it significantly disperses and reduces power caused by cable vibration to protect cable very well.
Select the proper type and quantity of spiral vibration damper according to cable diameter and span length .(For the detail , Referring relative table).
The damper must be installed in such a way that the gripping section is placed towards the tower and the damping section towards the free span .No special tools are required for installation.
