70 section OPGW optical cable conductor pre twisted wire anti vibration hammer hot-dip galvanized steel twisted wire tuning fork hammer

Description :

　　On high-voltage overhead lines, a small hammer called an anti vibration hammer is often hung on the wires near the insulators on both sides, which is designed to reduce the vibration of the wires caused by wind force. High voltage overhead power lines have high pole positions and large spans, and when the wires are subjected to wind force, they will vibrate. When the wire vibrates, the working conditions at the wire suspension are the most unfavorable. Due to multiple vibrations, the wire may experience fatigue failure due to periodic bending. When the span of overhead power lines is greater than 120 meters, anti vibration hammers are generally used to prevent vibration. For steel cored aluminum wire, the weight of the anti vibration hammer is

　　W=0.4d-2.2 (kg)

　　In the formula, d represents the outer diameter of the wire (in millimeters)

　　The anti vibration hammer is composed of a certain mass of heavy hammer, high elasticity, high-strength zinc steel stranded wire and wire clamp
