Product Introduction
Transmission Line Aluminum Alloy Vibration Damper
On the high voltage overhead line, a small hammer is often hung on the wire near the two sides of the insulator. This small hammer is called the anti-vibration hammer, which is designed to reduce the vibration of the wire due to wind pull. The pole position of high voltage overhead line is high and the gap is large. When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working condition of the conductor suspension is the most unfavorable. Due to multiple vibrations, the conductor will suffer fatigue failure due to periodic bending. When the overhead line file distance is greater than 120 meters, the anti-vibration hammer is generally used to prevent shock. The installation position of the anti-vibration hammer should be determined according to the construction requirements. After the anti-vibration hammer is installed, it can produce a motion opposite to the vibration phase of the wire, so that the vibration of the wire can be eliminated or weakened.
Precautions for installing a shock hammer
1, according to the calculation, if the installation position of the anti-vibration hammer is on the inner skein, it is not necessary to install the wire protection bar, and it can be installed directly.
2. If the calculated installation position of the anti-vibration hammer falls on the optical cable, it is necessary to install a wire protection bar, and pay attention to the distance between the end of the wire protection bar and the end of the twisted wire at least 50mm.
3. If the installation position of the shockproof hammer falls on the outer strand, it can be offset a little and installed directly on the inner strand, but the center of the shockproof hammer is more than 50mm from the end of the outer strand.
4, drooping head toward; The sledgehammer heads towards the tower.
Since December 1998, the 4D series anti-vibration hammer has been introduced into China, and nearly 1 million sets have been used in transmission lines and power optical cables. Compared with the traditional national standard anti-vibration hammer, it has better appearance, anti-corona and anti-radio
