Product Introduction

Product Description

Stockbridge Damper

Stockbridge damper is used to control or suppress the wind induced vibration of overhead conductors. The Stockbridge damper targets oscillations due to aeolian vibration; it is less effective outside this amplitude and frequency range. Aeolian vibration is nothing but winding induced oscillation which has amplitude of millimeters to centimeters and a frequency of 3 to 150 Hz. Aeolian vibration causes damaging stress fatigue to the cable. It causes failure of conductor strands. It is connected at two end of the transmission power line span. The vibration damper has a length of steel messenger cable. Two metallic weights are attached to the ends of the messenger cable. The center clamp, which is attached to the messenger cable, is used to install the vibration damper onto the overhead conductor.

Materials

Helical rods: aluminium clad steel

Clamp: aluminium alloy
Counterweights: galvanized steel

Messenger cable: galvanized steel

Features：

Control aeolian vibration in each span of the line within the internationally accepted limits with the minimum number of units Maintain damping capacity over the entire range of ambient temperatures and for the whole expected life of the line Be free from corona at the maximum voltage of the line when installed on the phase conductors Be installed and removed on energized lines; Be maintenance-free for the whole expected life of the line Maintain a suitable grip on the cable resisting the loosening effect of vibrations Guarantee that individual components are secured against becoming loose in service
