Non-slip type vibration damper is composed of hammer and helical clip. It can reduce the breeze fatigue damage of wire and optical cable.
Non-slip type vibration damper is composed of hammer and helical clip. It can reduce the breeze fatigue damage of wire and optical cable. But if the vibration damper produce the slip it will cause greater damage to the wire, so must be ensure to installed with reasonable weight and position .
The non-slip type vibration damper we provided with particular weight and reasonable shape design ,it can produce multi resonant frequencies and effective absorption the different frequencies of vibration. Adopting the helical structure form of installation, it have large adhesion area and evenly distributed the Adhesion force, without stress concentration, can keep the constant installation moment of force, ensure the products don't have any slip phenomenon, effectively prevent the fatigue damage of cable, extension the wire service life .
Specification of Non-slip type Vibration damper
| Type | Available Dia.of Cable | Weight(kg) | |
| Min. (mm) | Max.(mm) | ||
| 4D-20Y | 7.5 | 22 | 1.4 |
| 4D-30Y | 7.5 | 22 | 2.5 |
Recommend allocation of vibration damper for OPGW
| Cable Dia.(mm) | Span(m) | |||
| d<12 | 100~300 | 300~600 | 600~900 | |
| 12≤d<22 | 100~350 | 350~700 | 700~1000 | 1000~1200 |
| ( recommend quantity of vibration damperlspan) | 2 | 4 | 6 | 8 |
Note: For safety reason, quantity of vibration damper would rather surpass than lack at critical span.
