OPGW Transmission Line Fittings , Iron Spiral Vibration Damper
* 4D vibration damper Function:Preformed rod gripping vibration
hammer is improved one of common SH4D vibration proof hammer’s
gripping part. Its vibration proof property is similar with the
* 4D vibration damper Feature:Use preformed rods for gripping part
and the gripping part is firm and steady, safe and reliable. This
can avoid the displacement of vibration proof hammer for loosing of
the aluminum splint dues to the longtime using, the displacement is
worse when the cable’s slope is bigger. Using preformed rods for
gripping can also omit armor rods and its structure is simple and
installation is convenient. Don’t need any tools.
* 4D vibration damper Composition:vibration proof hammer and
gripping preformed rods.
* Spiral Vibration Damper 1.Simple structure 2.Good anti-vibration
Hammer: Be made of Hot Galvanized Iron.
Suspension line: 19 shares a special galvanized steel strand.
Clamp: Aluminum Alloy.
Preformed armour rods: Aluminum Alloy.
Introduction&Application of vibration damper
Damper (VSD) by a certain weight, the size of the hammer, high
elasticity, high strength galvanized steel wire and high strength
aluminum alloy clamp, etc.Parts. Cover wide frequency range, high
power dissipation of energy, can effectively lead breeze vibration
of dissipation of energy, reduce the vibration levels of lead,
extend long wire life. Can be directly installed on the wire, when
installed in the overhead ground wire composite (OPGW) on, the need
to install the damper on the special care lines.
1. Such as the damper installation location falls within the
twisted wire on, you do not care lines installed directly to the
2. If the calculated vibration damper cable installation position
falls on, you need to protect installation of lines, and pay
attention to retaining the end of the line distance of at least the
end of twisted wire 50mm.
3. If the calculated vibration damper installation location falls
outside the twisted wire on, you can shift a little, direct
installation, including twisted wire, but outside the twisted wire
from the vibration center of the end of more than 50mm.
4. Hammer towards: sledgehammer head-pole side.

Spiral vibration damper is made of PVC material with high strngth
and elasticity. It is recommended for vibration insulation of ADSS
fiber and OPGW fiber.
Simple structure, convenient installation, easy maintaining, and
little limit to installation position.
Spiral vibration proof damper consists of gripping section and
vibration proof section.
Spiral vibration damper is made of high-strength, antigenic and
high-elasticity PVC plastic, easy
to install and operate. It’s an interference type damper to
attenuate vibration amplitude by
impact with its damping section and especially designed for ADSS
cable and OPGW cable of
diameter less than 12mm.
For cable diameter(mm)
Grip length L1 (mm)
Total length L2(mm)
Note: meaning of letters and numbers: FL-spiral vibration damper;
"-" after suitable cable
It dissipate energy by shocking with the cable, so decrease the
vibration in the wind, protect the fiber and fitting
