Twisted Pair Vibration Damper
PLP's Twisted Pair Vibration Damper is designed to withstand the high dynamic stresses of twisted pair conductor autorotation while mitigating aeolian vibration. Autorotation is a torsional instability under wind flow that can cause rotational oscillation about the span axis, causing high stresses at conductor connections. Autorotation has been observed to damage Stockbridge-style dampers for twisted pair conductor. The Twisted Pair Vibration Damper utilizes an elastomer damping element and elastomer lined clamp to withstand autorotation and provide sufficient aeolian vibration damping.
-
Elastomer damping element designed to withstand the stresses associated with autorotation better than a Stockbridge damper for twisted pair conductor
-
Specially designed elastomer-lined clamp reduces static and dynamic stresses on the conductor
-
Elastomer damping system was initially developed in conjunction with Hydro-Québec for severe environment applications
-
Corona-free up to 345 kV
