OILES Cable Vibration Damper

Cable-stayed bridge cables are inherently prone to swaying due to tension, and winds above a certain wind speed or winds during rainfall can cause large vibrations.
The Oiles Cable Vibration Damper is a device that suppresses those cable vibrations via the shear resistance of an Oiles viscous body.

• The Oiles Cable Vibration Damper consists of its cover, which is attached to the cable, and its body, which is mounted on the girder.
• The body is divided into two chambers that are filled with viscous material. The cover’s oscillator (two thin plates inside the attached cover) is inserted from above, creating four shear surfaces on the viscous body. (The dimensions below are for reference only). ）

• Inspections
  If the damper is subjected to strong winds such as typhoons or vibrations caused by earthquakes with an intensity greater than 5, conduct a temporary inspection to confirm that there is no damage to the mount or main body and that there is no leakage of viscous material.

• The Oiles viscous body is a high-viscosity polymer with excellent flame resistance, weather resistance, and thermal stability.
• The Oiles viscous body degrades little over time and can maintain vibration control a long period of time.
