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.Composition: galvanized cast iron hammer head, hot-dip galvanized steel stranded wire, aluminum alloy clamp, stainless steel bolts, etc. Features: The anti-vibration hammer adopts a special tuning fork structure, which can generate four resonant audio frequencies, which can well cover the vibration frequency range of wires and ground wires in reality. It can form a stable vibration frequency, and can well control various levels of breeze vibration, thereby eliminating wire fatigue and ensuring the life of wires and ground wires. Advantages: 1. With the typical Harrow design, the frequency protection is sufficient to spread in the wide frequency range from 6Hz-150Hz, and there are four resonance frequencies in this range. 2. The hammer head is glued to the wheat harvesting hanging wire, which can bear the mechanical load under the conditions of installation, maintenance and operation. 3. The shape design does not accumulate ice or water. 4. The installation side does not cause damage to the wires and ground wires. 5. Anti-vibration hammer adopts anti-corona design, which can prevent corona from happening. 6. Anti-vibration hammer The hammer head adopts a tuning fork structure, which can generate 4 resonance frequencies and effectively absorb vibrations of different frequencies. 7. Pre-twisted installation is adopted, the adhesion is evenly distributed, the stress is concentrated, and there will be no slippage. 8. Easy to install, without any special tools, it can be quickly and easily installed on site with bare hands, and can be completed by one person.
