4D-20 pre-twisted wire anti-shock hammer
Release time:
2019-12-06 01:13
The anti-vibration hammer is designed to reduce the vibration of the wire due to wind shock. The high-voltage overhead line has a high rod position and a large pitch. When the conductor is affected by wind, it will vibrate. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will undergo fatigue damage due to periodic bending. When the overhead line spacing is greater than 120 meters, the general use of shockproof hammer shockproof.
On high-voltage overhead lines, a small hammer is often hung on the conductor near both sides of the insulator. This small hammer is called an anti-vibration hammer, which is set up to reduce the vibration of the conductor due to wind shock. The high-voltage overhead line has a high rod position and a large pitch. When the conductor is affected by wind, it will vibrate. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire will undergo fatigue damage due to periodic bending. When the overhead line spacing is greater than 120 meters, the general use of anti-vibration hammer shockproof. For steel core aluminum wire, the weight of the shock-proof hammer is
w = 0.4 d-2.2 (kg)
where d -- outer diameter of wire (mm)
Installation check
The installation position of the shock-proof hammer shall be determined according to the construction requirements. After the anti-vibration hammer is installed, it can produce motion opposite to the vibration phase of the wire, so that the wire vibration is eliminated or weakened.
The installation of the shockproof hammer shall be equipped with the protective line, so when configuring the shockproof hammer, the monofilament diameter * 2 of the cable with the protective line is generally the model of the optical cable shockproof hammer.
