Vibration Damper/Armour Rod

Vibration Damper/Armour Rod

■ Introduction:

The company offers a 4D series of anti-vibration hammer tuning fork design for Stockbridge, multi-resonance sound damping devices, mainly used for weakening and fragmentation of fiber optic cable due to aerolian vibration generated by the impact energy.

■ Configuration for OPGW Dampers:

OPGW dampers are typically used based on the cable diameter and span. The recommended quantity of dampers per span is as follows:

 

For cables with a diameter of less than 12 mm:

• 100–300 m span: 2 dampers

• 300–600 m span: 4 dampers

• 600–900 m span: 6 dampers

 

For cables with a diameter between 12 and 22 mm:

• 100–350 m span: 2 dampers

• 350–700 m span: 4 dampers

• 700–1000 m span: 6 dampers

• 1000–1200 m span: 8 dampers

■ Configuration for ADSS Dampers:

ADSS dampers are similarly installed based on cable diameter and span length. The recommended number of dampers per span is:

 

For cables with a diameter of less than 12 mm:

• 100–250 m span: 1 damper

• 250–450 m span: 2 dampers

• 450–700 m span: 4 dampers

 

For cables with a diameter between 12 and 22 mm:

• 100–250 m span: 1 damper

• 250–500 m span: 2 dampers

• 500–800 m span: 4 dampers

• 800–1000 m span: 6 dampers

Note: For critical spans, the number of dampers should be adjusted for safety, either by increasing or decreasing the quantity.
