Description
helical suspension clamp for OPGW Cable
OPGW preformed suspension clamp is mainly used to support the suspend OPGW cable. It is suitable for the OPGW cable, conductor and grounding wire on transmission line. It is recommended used on the line with turning angle less than 30 degree.
This helical suspension clamp is the connecting fitting that hangs OPGW cable onto the poles/tower in
the transfer line, the clamp can decrease the static stress of cable at hanging point, improve anti vibration capacity and restrain dynamical stress caused from wind vibration. It also can ensure that the cable bend doesn't exceed allowable value and cable doesn't generate bend stress. By installing this clamp, the various harmful stress concentrations can be avoided, so the additional damage wastage shall not occur in the optical fiber within the cable.
For example
Application to RTS≤70KN OPGW
The broken strength:70KN.The holding strength 14%-20%RTS
Features
1. High mechanical Strength
2. Steel strip type suspension clamp suitable for small cable passing through small span line.
3. Small span tangent clamp.
4. Easy installation of rust and corrosion protection.
Application
