Spiral vibration isolator
It’s suited for ADSS cable and OPGW cable whose diameter is less than 12mm. The spiral vibration damper is the interferometric vibration isolation equipment which makes damping action to consume the power of cable vibration and inhibits the cable vibration, as a result, protect the cable.Specification table

Instruction
1. Choose the spiral vibration isolator according to the cable diameter.
2. After installation, the tight part should be close to the tower/tower side, and the distance between the corner of tight part and the corner of tension clamp or suspension clamp should be about 12cm. We can install several spiral vibration isolators along the cable, or install several ones in the same place simultaneously.
3. Ensure the amount of every span according to the tension and the size of span, generic disposition is:
Span | Amount |
<100m | 0 |
100-250m | 2 |
250-400m | 4 |
400-800m | 6 |
