Description
Technical Field

[0002] On high-voltage overhead lines, a small hammer is often hung on the conductors near both sides of the insulators. This small hammer is called an anti-vibration hammer. The anti-vibration hammer is designed to reduce the vibration of the conductors caused by wind. The poles of high-voltage overhead lines are high and the span is large. When the conductors are affected by wind, they will vibrate. When the conductors vibrate, the working conditions at the conductor suspension point are most unfavorable. Due to multiple vibrations, the conductors will suffer fatigue damage due to periodic bending. When the overhead line span is greater than 120 meters, anti-vibration hammers are generally used for vibration prevention.
[0003] The existing anti-vibration hammer is installed on the outside of the optical cable by winding a steel wire rope around a wire clamp. After installation, the anti-vibration hammer cannot ensure the stability of the connection with the optical cable. Once the steel wire rope is oxidized and loses its toughness, the anti-vibration hammer is easily caused to fall due to vibration, and cannot play the role of shockproofing for the optical cable. In order to solve this problem, an optical cable anti-vibration hammer is proposed. Utility Model Content
