Improve The Vibration Resistance And Anti-galling Capability Of Suspension Clamps.

In transmission line structures, section cable suspension clamp serves as both a suspension point and conductor support. To address line galloping caused by wind vibration and ice loads, one design solution involves introducing a damping mechanism into the suspension structure of section aerial cable suspension clamps, dissipating vibration energy through an additional mechanism.

The "suspended anti-galloping device" utilizes an air damper and spring system. By incorporating a variable-diameter flow channel, when the conductor vibrates under dynamic loads, the kinetic energy is converted into elastic potential energy, which is then dissipated through airflow friction, thereby reducing the amplitude and frequency of vibration.

In this structure, section angle suspension clamp is located at the top to fix the conductor, while the lower section is a sealed damper containing a piston and spring. When vibration occurs, the piston moves, causing a change in the air chamber volume, resulting in air pressure fluctuations that generate a reaction force. Combined with the flow-limiting orifice design, this further introduces air resistance and frictional energy dissipation. This process corresponds to the absorption and suppression of energy during conductor vibration.
