OPGW Transmission Line Fittings , Iron Spiral Vibration Damper


Quick Detail:


* 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 common one.

* 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 function


Description:


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 installation.

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.
