OPGW Vibration Damper

Structure：

Securing clamp (Aluminum alloy )

Messenger cable –(Galvanized steel wire)

Counter weights–( Galvanized forged steel)

Function:

Damper adopts special tuning fork type structure, it can generate four resonance frequencies which can cover actual ADSS/OPGW optical cable vibration range. After installing damper, the vibration amplitude of cable reduce syntony so as to suppress the conductor vibrations and ensure life of calbe, with satisfactory result in vibration proof.

The dampers are used to absorb the cable vibrations , The number of dampers is determined by the environmental conditions, the distance between towers, the type of ADSS/OPGW optical.

OPGW Accessories Hardware:

1.Splice closure
junction box is mainly used for protecting the fiber optic junction between two cables and reserve a section of fiber optic for maintenance in the box. The box has good leakproofness, anti-water and damp-proof feature and can not corroded in the power line.

                                                                            Joint box2. Suspension Clamp

Assembly with reinforced suspension clamp and neoprene inner covering ,especially designed for OPGW cables includes grounding clamps for tower connection .

3. Dampers
The dampers are used to absorb the cable vibrations , The number of dampers is determined by the environmental conditions, the distance between towers, the type of OPGW cable and the installation parameters

Structure
1. Clamp–(Aluminum )
2. M-12-rod-(Galvanized steel )
3. Support body –(Galvanized steel )    
4. Lock screw—( stainless steel )
 
5.Tension Assembly
Preformed tension especially designed for OPGW cable Includes grounding clamps for tower connection ,when the distance between two anchor towers is greater than maximum length of OPGW cable drums, there are special tension assemblies for installation in suspension towers, allowing a cable joint to be included.

                                           Dead-end fitting( Single)

Structure
1. Straight shackle -( Galvanized fogged steel)
2. Extension Link( Galvanized laminated steel )
3. Dead end –(Compression aluminum clad steel)
4. Thimble —(Cast galvanized steel)
5. Protection Splice–(Compression aluminum clad steel)
6. Ground clamp –(Aluminum)
 
Configuration 
There are three types of assemblies for installation in tension towers :
1.Passing tension assembly : for intermediate towers
2.Splicing tension assembly : for towers with joint boxes
3.Final tension assembly : for final towers
