Aerial Cable Damper

• Aluminum alloy.

• Designed to use the force of wind to aerodynamically reduce oscillation of

cable.

• Supplied with special heavy duty lashed cable supports and “D” lashing

clamps to secure to strand.

• Assembly instructions provided.

Installation:

1. Select proper size cable guard for application.

2. Place guard on cable over horizontal slots in Aerial

Cable Damper (ACD).

3. Insert lashed cable supports through horizontal slots.

Use two wraps and secure by bending end over top

of buckle. Allow 1/4” clearance between cable and

top of the ACD. The ACD must be allowed to swing

free with the wind.

4. Position lashing clamps inside lashed cable supports

and secure. Lashing clamps will restrict longitudinal

movement to cable area protected by cable guards.

5. Placement – The number of ACDs varies with the

length of cable span and terrain. The following is

recommended as a guide for maximum effectiveness.

Level Ground – Locate at span’s center for 125-170

ft. spans (Fig. 1). On spans 170-300 ft., locate two

ACDs, each one-fourth the total span length from

either pole. (Fig. 2)

Steep Grade – Locate one-tenth total span length

from pole at lower level on 125-170 ft. spans. (Fig 3).

On spans 170-300 ft., two ACDs are required. Locate

one at one-fourth the total span length from lower

pole. Locate second ACD halfway between first ACD

and uphill pole. (Fig. 4).

Note: When installing on Fig. 8 cable:

1. ACD should be secured to exposed strand.

2. ACD will have limited dampening effective in

extreme high wind conditions.
