“…In order to comprehensively evaluate the damping performance and antivibration efect of the new quadbundle spacer damper, the stifness-damping method was utilized in the tests. Te test results of a variety of regular quad-bundle spacer dampers [20] and the new quad-bundle spacer damper were selected for cross-contrast analysis. Specifcally, the damping performance of the new quadbundle spacer damper was evaluated by comparing their damping constant and their torsional stifness, and the antivibration efect of the new quad-bundle spacer damper was assessed by comparing the vibration energy dissipation in a single cycle.…”

Aiming at improving the handling efficiency and acquiring the satisfactory antivibration effect and damping performance, a quad-bundle spacer damper of 500 kV extra high voltage transmission lines was designed and developed based on a new rubber structure. Firstly, a mathematical vibration model of the spacer damper was constructed, and the structures of the defect-prone parts of the spacer damper were analyzed. Then, the structure was optimized based on the defect analysis, the clamp with fast installation as well as removal and the damper joint with superior performance were designed. On this basis, a new quad-bundle spacer damper was developed. Last but not least, the handling efficiency of the new quad-bundle spacer damper was evaluated, and performance tests were conducted according to the IEC standards. The evaluation and test results show that the handling efficiency, antivibration effect, and damping performance of the new quad-bundle spacer damper are significantly improved compared with those of the regular quad-bundle spacer damper, which provides a guarantee for the safe operation of 500 kV extra high voltage transmission lines.
