Vibration of Transmission Line And How To Eliminate It

The vibration of the output line usually has the following types and elimination methods:

External product :Depending on the properties of optical cables, different products are selected to reduce vibration. For ADSS optical cables, helical vibration damper is the best choice. This product is made of PVC that is resistant to high temperature and UV rays, and has good durability and flexibility. For OPGW optical cables, vibration dampers are the best choice. By selecting appropriate models with different cable diameters and fixing them with armor rods, vibration dampers can effectively reduce vibration.

Cable own vibration: Most cables reduce vibration through wind vibration. This effect is particularly significant in high-altitude cables.

Optimize line design: Reduce the stress on the cable by shortening the length of a single cable between towers.

Adjust the wire tension: Adjust the cable tension strength according to the actual situation to avoid excessive or too small vibration caused by too high or too low tension, which affects the operation of the power system.

Maintenance and protection of power systems: Regularly check the status of cables and power towers, pay special attention to rust, and maximize the life of cables.

The vibration and elimination methods of the output circuit are different,choosing according to the actual situation.

Reducing the damping force of the cable is mainly divided into the cable itself and external reduction, which can protect the cable and extend its service life.
