INSTALLATION INSTRUCTIONS

CONVENTIONAL

COMPRESSION SPLICES

FOR
ACSS CONDUCTORS


The
full
-
tension
splice assembly consists of a steel sleeve and an aluminum splice body.
P
arts are
marked
with die size, manufacturing date and FARGO catalog number

(steel sleeve) or part number
(aluminum splice body).

Aluminum body marks also include conductor type and size.



1.

Prior to installation the conductor must be clean, straight and in lay.

Any bend
in conductor
section to b
e spliced will tend to make
splice
fittings
bow during compression.

2.

Conductor t
ensioning grips
should be at least (10) feet from
conductor ends
to reduce aluminum
strand birdcaging during compression of the
aluminum
splice
tube.
Tension grip
s

must be of a
size and type approved by the conductor manufacturer.

3.

Remove the protective plastic and end caps. Be sure the bores of the fittings are clear of foreign
matter. Do not remove any of the grit coating inside the steel barrel.

Ins
ert the conductor into
the
aluminum

splice
body and slide the
splice
body over the conductor
, allowing working room to
install the steel splice sleeve on conductor core
.

4.

Cut
-
mark the aluminum strands at a distance, from conductor end
s
, equal to the depth o
f the bore
in the
s
teel
sleeve
plus

¾” to
1


to allow f
or elongation of the steel
sleeve
b
arrel during
compression. Tape wrap
the conductor

¼ inch to
the span side of the cut mark. Expose the steel
core by removing the aluminum strands to the cut mark.
Do not nick the steel strands while
cutting away the aluminum strands
.

5.

Moun
t

the SH
die

set

specified on steel deadend barre
l in press
. I
nsert conductor core into the
steel
sleeve until it bo
ttoms in the sleeve bore.
L
ubricate die faces and steel

sleeve
half to be
compressed first
with
light
-
weight
oil

or spray lubricant
.

With sleeve seated in one die half, make
the first compression at the knurl mark on sleeve
side
with conductor core inserted. Continue
compressions out to sleeve end. Overlap crimps sli
ghtly
-

to prevent the formation of ridges
between adjacent crimps. Assure complete die closure with each crimp.
Keep
steel barrel
lubricated and fully seat
ed

in one die half as dies close.
A BOWED

STEEL SLEEVE
MAY
PREVENT THE ALUMIMUNM BODY FROM SLIDING INTO PLACE
.
-

Repeat the process
to
compress opposite side conductor core into the
steel sleeve.

6.

Mark conductor on both sides of the
steel sleeve center
, at a distan
ce equal to half the length of
the aluminum splice

plus 2

inches. These
marks

will be used to center
the aluminum body

over
the steel sleeve.

7.

Mount the AH die set specified on the aluminum splice body in the press.

8.

With a clean stainless steel wire brush (V
-
brush
type
recommended),
aggressively

brush

the
conductor
end on
the joint side where the aluminum splice body is parked
. Brush the full
conductor
circumference
from
tape wrap
to
just
short of the aluminum body
centering mark
.
Immediately a
pply a generous coat of
FARGO Hi
-
Temperature Joint Compound (HTJC)

over
the
j
ust
-

b
rushed conductor surface
.

9.

If installing splice with span under hoist tension, back off hoist to shift
span
tension to the
fully
compressed

steel sleeve. This will pull the conductor straight on both sides of the joint and allow
the aluminum splice body to slide more easily into place.

Having the conductor pulled straight will
also minimize bowing of the alumi
num deadend body as it is compressed.

As hoist tension is
shifted to the steel
sleeve
, confirm that the aluminum conductor end
s

do not move away from the
steel
splice sleeve ends
. If any aluminum slip
occurs
, reverse it by re
-
applying full hoist tension.

10.

Slide the aluminum splice body over the compound
-
coated area to near the tape
-
wrapped
conductor end. Remove tape wrap. Wire brush the exposed end strands and immediately coat
with HTJC.

11.

Aggressively
wire brush

conductor
on the second joint side

between

the tape wrap

and
aluminum body centering mark
. Fully coat the area just brushed
wi
th HTJC.
Slide the aluminum
body until it
just
captures the
conductor strand ends on second joint side.
Remove tape wrap and
aggressively brush the
small area exposed by

tape removal. Immediately coat this small area with
HTJC.

12.

Slide the aluminum
splice
body over the steel
sleeve
until
it is centered between the marks
applied
in step 6. Remove and set aside the splice body filler port plug.

13.

With a caulking gun, inject
F
ARGO Hi
-
Temperature Joint Compound (HTJC)
, through the filler
port
, until compound begins to flow out between the aluminum body and
conductor at one
end
of
the splice.

Hammer the aluminum plug into the filler
hole until it is flush with the splice tube
su
rface, and
peen
plug at one edge to help secure it in place
.

14.

L
ubricate
AH
die faces
and
aluminum body crimp

zone
with
light
-
weight oil

or clean plastic wrap
material
.

(I
f plastic used as lubricant, ensure that it wraps completely around the
splice
tube
,

fully
covering both die face during each compression).

F
ir
mly seat
the splice
body
in one die half

and

make the first compression at the knurl
mark on first splice side.

Continue with overlapping
compressions
to the end
s

of the
splice
. Keep the compression zone
s

well lubricated and keep
aluminum body seated in one die half as dies close
. Repeat for opposite splice side.

15.

Remove the hoist and tension grip
s

and spray the c
onductor
spans with WD40, or equivalent,
penetrating lubricant
in
the area
s

where the grip
s
had been applied.
Using a wood or rubber
mallet
,

tap the conductor strands in the areas where the grips had been to loosen strand
-
to
-
strand
binding caused by tension grip pressure. This will help work expanded strand (birdcage) out into
the span.

NOTE: DO NOT CRIMP
SPLICE
IN THE REVERSE DIRECTION

16.

As c
ompressions are completed
,

wipe off excess joint compound as it is expelled from the
deadend body.
R
emove any
die
flash and file or sand for a smooth appearance.
