Information

Vibration Dampers work to cancel damaging fatigue caused by wind-induced vibration.Most tuned damping devices operate best near their natural frequencies. vibration dampers are designed for efficient transfer and dissipation of energy over a wide spec_x005ftrum of frequencies. They feature all aluminum clamp construction to match expansion/contraction of conductor and break-away bolts for easy installation and proper torque.

Product Description

1.The vibration damper is composed of galvanized cast iron hammer head, hot-dip galvanized steel strand, aluminum alloy clamp, etc. It is durable and the quality is guaranteed.

2.Can effectively suppress the breeze vibration of the optical cable and wire,safe and reliable.The installation of pre-twisted wires or bolts improves stability and reduces slippage.Unique shape is easy to eliminate water and ice deposits, special weather does not affect the use, high efficiency.

3.Using a typical unique design, the basic principle is to dynamically absorb energy, frequency protection is sufficient to spread in a wide frequency range from 6Hz-150Hz, and there are four resonance frequencies in this range.
