Features a preform structure that ensures even distribution of clamping strength between the damper and conductor across a 30-60cm length area. This design effectively protects conductors and prevents stress concentration.
Utilizes rotation and swing of hammers at both ends to generate rated frictional damping force, enabling galvanized iron wire strands to slide against each other and dissipate swing energy efficiently.
Stockbridge dampers are engineered to reduce wind-induced vibration in overhead transmission line wires. As essential cable accessories, they ensure the integrity and longevity of electrical systems by minimizing vibration-related damage.
- High probability of conductor vibration due to unstable airflow causing breeze vibration
- Small amplitude (typically under 10mm) with high frequency (3-100Hz)
- Significantly affected by terrain, span, erection height, and tension
- Vibration waves distribute as standing waves with sine waveform patterns
