Product Description

Uses: Usage

 It dissipate energy by shocking with the cable, so decrease the vibration in the wind, protect the fiber and fitting.

 

Features:

A, one type shock absorber. It is very useful for a little diameter high frequency transmission line and optic fiber cable.

 

B, gripping section make sure that the cable don't move, the damping section provide mechanical interaction between damper and conductor.

 

C, easy installation.

 

D, Eliminates damage caused by wind and god vibrations

 

E, Reduces overall vibration of bare conductors

 

F, Made of weather-resistant, non-corrosive plastic

 

H, Large spiral damping section for cables, with smaller clamping section to gently clamp conductors

 

I,Marked conductor ranges and color coded to indicate cable diameter size ranges

 

J, Available in standard and high quality span lengths

 

Applications.

Distribution Range

Conductors between 0.250 in. and 0.500 in. outside diameter

Spans over 800 feet

Order Information:

Confirm the configuration quantity of every helical vibration rod according to the span in the transmission line.:

number	Span L（m）	Configure of each span (root)
1	100 not less than L less than 250	2
2	250 not less than L less than 500	4
3	500≤L＜750	6
4	750≤L＜1000	8

How to Install a Spiral Vibration Damper (SVD)

Spiral Vibration Dampers need to be placed in the proper location to ensure success. They should be mounted near but not in contact with the following support devices (leave approximately 6-8 inches of clearance)

 

Armor bars

Cable suspension clips

dead center

or other electrical hardware.

SVD installation is easy and follows more or less the same procedures of all manufacturers.

 

Step 1: Properly install the ADSS (All Dielectric Self-Supporting) cable between poles or any fixed points along the line. This should be done according to the manufacturer's instructions.

 

Step 2: Place the SVD close to the ADSS cable, with the grip end away from you and the damping area close to you. This is done to determine the proper clearance to allow before beginning installation.

 

Note: As previously stated, the SVD should not touch the armor bar or any hardware at the end. There should be approximately 8 inches of clearance from the end of the hardware to the SVD.

 

Step 3: Install the SVD by quickly wrapping the wire from the gripping end or tighter end. Continue until the entire length of the SVD wraps around the cable.
