A shock hammer is just a piece of iron rod. Because it is hung at the suspension point of the tower pole of the line to absorb or weaken the vibration energy, change the swing frequency of the line, and prevent the line from vibrating or dancing; the hammer head is made of gray iron, painted, and the rest are hot-dip galvanized steel parts; The anti-vibration hammer is designed to reduce the vibration of the wire due to the wind; the high-voltage overhead line has a high pole position and a large span. When the wire is affected by the wind, it will vibrate. When the wire vibrates, the working conditions at the suspension of the wire are the most unfavorable; due to repeated vibrations, the wire will suffer fatigue damage due to periodic bending; when the span of the overhead line is greater than 120 meters, a shock-proof hammer is generally used to prevent shock.
