1. Damping and Vibration Reduction
Uses silicone rubber as the damping element, which effectively absorbs conductor vibration energy and reduces vibration amplitude.
Provides excellent suppression of both aeolian vibrations (high-frequency, low-amplitude) and sub-span oscillations (low-frequency, large-amplitude), minimizing fatigue damage to conductors.
2. Lightweight Structure
Typically adopts a double-plate structure made of aluminum alloy, offering low mass to reduce conductor load.
Meets anti-corona requirements for high-voltage applications by optimizing surface geometry and material conductivity, suppressing partial discharge.
3. Fixed Spacing Maintenance
Ensures four-split conductors maintain a constant inter-phase spacing, preventing sub-conductors from whipping or colliding under loads such as:
Wind force (aerodynamic induced vibrations)
Ice loads (uneven mass distribution)
Short-circuit currents (electromagnetic repulsion/attraction)
Maintains the conductor bundle’s geometric stability, ensuring consistent electrical performance (e.g., uniform potential gradient, reduced corona loss).
