How Does A Small Size Damper Reduce Vibration in Transmission Lines?

At high altitudes, high-voltage cables are usually more affected by the wind because the wind encounters less resistance at high altitudes. The wind vibration of the cable itself will reduce the resistance to protect itself, but cables on the seaside and cables in monsoon climate areas are often affected by typhoons, the cable itself cannot absorb shock, therefore we need Small Size Dampe.

The quantity of Small Size Damper depends on the pitch range. 100-300 meters requires 2 pieces, 300-600 meters requires 4 pieces, 600-900 meters requires 6 pieces, and 1000-2000 meters requires 8 pieces.

The working principle of Small Size Damper

Fixing: Choose different models according to the clamp dia range, and then use the arour rod to fix it on the cable.

Dispersed damping force: When the wind is too strong, the damper uses the gravitational inertia to cause friction between the armor rod and the cable to neutralize the damping force brought by the wind, thereby dispersing the impact of the wind on the cable.

Small Size Dampers are installed on high-voltage cables to reduce wind-induced vibrations by using gravitational inertia and friction to disperse the impact, with the quantity depending on the cable span.
