Back-Pull/Stationery Reel - Making Expansion Loops and Lashing

Make Your Expansion Loop Prior to Lashing

If an expansion loop is called for (see Aerial Installation/3.4), attach the mechanical bender to the strand and

form the loop per the manufacturer’s directions. Do not remove the bender until at least 50 ft (15

meters) of the cable has been lashed.

Attach the Lashing Wire Clamp

Place the lasher on the strand. Wrap the lashing wire twice around the strand

in the same direction as the twist in the strand and in the lay of the strand.

Pass the lashing wire between the washers of the lashing wire clamp without

overlapping the wire. Wrap the wire around the clamp to the post on the

opposite side of the clamp and wrap it twice around the post. Cut the wire

and tuck it between the halves of the lashing wire clamp. Use

appropriate-sized spacers to prevent the cable from rubbing against the pole

hardware. NOTE: it is essential that double lashing be used with two or more

cables, all trunk cables and at street and RR crossings.

Place the cable within the lasher. A cable positioner may be arranged ahead of the lasher for extra guidance as

the lasher is pulled toward the reel. Pull the lasher toward the reel with a wire or rope.

It is important to minimize the sag on cables as they enter the lasher. Leave the cable blocks in place until the

lasher is close enough to support the cable. As the lasher approaches cable blocks, either remove them with a

cable block lifter or push the cable blocks to the next pole by utilizing a cable block pusher.
