Description

Technical Field

[0001] The utility model relates to the technical field of spacer dampers, in particular to a two-split ball-joint spacer damper. Background Technique

[0002] The two-split ball-joint spacer damper is a device used to support and protect conductors. It mainly consists of a chuck body and a connecting rod, and is connected by a ball joint, so it is named the ball-joint spacer damper. The two-split ball-joint spacer damper is usually used in overhead transmission lines, especially on the two-split conductors of 220 kV and 330 kV.

[0003] The ball-joint spacer damper is usually installed in the middle of the span, one every 50 - 60 meters, and its own weight will generate an additional tensile force on the conductor. This continuous gravitational force causes fatigue of the conductor near the clamping point, thereby reducing the mechanical strength of the conductor. Due to the spacer damper falling under gravity, the conductor is more likely to vibrate under the action of wind. Long-term gentle vibration will cause damage to the conductor near the clamping point, such as broken strands or cracks, further reducing the service life of the conductor. Therefore, it is necessary to provide a two-split ball-joint spacer damper to disperse the tensile force at the clamping point and improve the gripping force of the spacer damper.
