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.
Suspension Clamp Application
Preformed suspension clamp is mainly used on the overhead transmission line, ground wire and so on. Its function is similar with common suspension clamp. Its advantage will present mostly on the line with ultrahigh voltage of more than 110KV and large span. The suspension clamp has two types. One is single suspension clamp and the other is double suspension clamp. The double suspension clamp is suitable for the line whose span is over 800 meters or corner between 30 and 60 degree.
