Vibration dampers

APPLICATION:

VORTX Dampers respond to wind induced line vibration that is characterized by high frequency, low amplitude motion due to aeolian vibration. The VORTX damper with Large and Small weights can achieve greater power dissipation and frequency response performance than "symmetrical weight" Stockbridge damper designs.

VORTX Dampers can be clamped directly onto most aluminum based conductors including ACSR, AAC, AAAC and ACAR. PLP® Protector Rods should be considered for applications on aluminum conductors with relatively soft outer aluminum strand construction such as ACSS. Protector rods are designed to reduce direct clamping stress on cable vulnerable to surface or core damage – this

includes fiber optic cable designs such as ADSS and OPGW.

Generally as conductors and cables increase in size they tend to vibrate at lower frequencies. The VORTX Damper is more effective for larger size conductors while the Spiral Vibration Dampers (see Helical fittings ) are generally more effective for the smaller diameter cables that can vibrate at much higher frequencies.

The degree of protection required on a specific line depends upon a number of factors such as: *line design, local climate, tension, exposure to wind flow, and line vibration history in the area*. With assistance from your local PLP Sales Representative, the necessary information can be assembled for review and followed up with detailed PLP recommendations for your system.

VORTX Dampers meet the requirements of International Standard IEC 61897.
