Cushion-Grip Spacer Damper (Type “B” & Type “C”)

For standard 18″ (457mm) sub-conductor spacing, the catalog numbers is: CGSDT-X45YZ.
Where "T" is "B" for Type “B” or “C” for Type “C”.

"YZ" is taken from the conductor range table. X is 2 for Twin, 3 for Tri, 4 for Quad, 6 for Hex.

For Example: CGSDB-34529 is a Type “B” Spacer Damper for a Tri Bundle of conductors within a diameter range of 1.107″ to 1.146″ (28-29 mm).

Armor-Grip Suspension

For repair of fatigue-damaged conductors, a specially designed ARMOR-GRIP Suspension can be applied over Armor Rods to extend the life of the conductor. Wrench-formed rods must be removed when conductor fatigue occurs under them; a splice is then applied to the fatigued area and the AGS Unit is applied over the splice. When considering the use of this product, consult the Factory for an engineering recommendation.

For use on: ACSR, All-Aluminum, Aluminum Alloy,AWAC©, Compacted All-Aluminum, Compacted ACSR, ACSS, ACSS/TW.

Armor-Grip Suspension Double

For Line Angles Between 30˚ and 60˚

For use on: ACSR, All-Aluminum, Aluminum Alloy, AWAC© Compacted All-Aluminum Compacted ACSR, ACSS, ACSS/TW.

Spiral Vibration Damper

Length: Assists in identification of conductor size, corresponding to tabular information appearing on following page.

Damping Section: Helically scaled for interplay of damper and conductor, to provide the action/reaction motion that opposes the natural vibration wave.

Note: Water/Canyon Crossings – due to the increased potential of laminar wind flow, an additional 50% more dampers per span should be added to the standard recommendations above for adequate protection. In areas that are prone to high levels of vibration or conductor tension is in excess of 18% RBS, consult Preformed Line Products for specific recommendations. Thermal Rating (Continuous) 125°C.

Vibration Damper For Over-head Shield Wire

The range of DOGBONE vibration dampers is a development resulting from our extensive experience and research in the field of conductor vibration control. The DOGBONE damper concept is based on the known and proven principles of the Stockbridge damper but embodies improvements which increase both power dissipation and range of frequency response beyond those of standard Stockbridge types. The performance of the DOGBONE vibration damper has been further improved using the latest CIGRE and IEEE recommended methods including I.S.W.R. Power Dissipation and Mechanical Impedance Testing.
