Fd/FF/Fr/Fdz 35-630mm2 Overhead Conductor Damping Device Power Fittings Dampers Anti-Galloping Devices

The overhead power lines are affected by meteorological conditions such as wind, ice, and low temperature, causing the lines to vibrate and dance. The vibration frequency is high and the amplitude is very small. The wind vibration causes the overhead wire to be repeatedly bent at the suspension point, causing material fatigue, resulting in strand breakage and wire breakage accidents. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flashover, resulting in serious accidents such as line tripping, power failure or burning of wires. A shock hammer is just a length of iron rod. Because it is hung at the suspension point of the line tower pole, it can absorb or weaken the vibration energy, change the swing frequency of the line, and prevent the line from vibrating or galloping. The hammer head is gray cast iron, painted, and the rest are hot-dip galvanized steel.
The anti-vibration hammer is designed to reduce the vibration of the wire caused by the wind. The pole position of the high-voltage overhead line is relatively high, and the span is relatively large. When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working conditions are the most unfavorable where the conductor is suspended. Due to multiple vibrations, the wire will be fatigued and damaged due to periodic bending. When the span of the overhead line is greater than 120 meters, an anti-vibration hammer is generally used for anti-vibration.
Factors causing vibration: distance, tension, wind speed, wind direction, ground wire and cable structure size, etc.
Scope of application: It is suitable for suppressing the vibration of wires and ground wires on overhead power lines.
Function: Eliminate or reduce the vibration caused by various factors during the operation of the optical cable, and protect the optical cable fittings.
