For use with Kits Repair 11A, 11B, 11C and 11D
Kit contents
Wraparound liner (two pieces)
2 Aluminium foils
2 Cleaning tissues
2 Branch-off clips
2 SCOP (small cable overheat protection)
2 Desiccant packs (16gm)
2 Abrasive strips
Alminium sheet (one piece)
1
Typical joint
4 Make a mark approx 50mm either side
of each cable butt. This will be the total
length of the joined liners.
Notes
1 Observe safety precautions as laid down
in the Engineering Safety Guides.
2 See ISIS EPT/CJT/C020 for general
information on D-Side closures.
3 “C” nozzle should be used for
installation.
4 Support the joint ensuring the cable
ends are supported before
commencing installation.
2 Using the supplied cleaning tissue, clean
all cables either side of the cable ends for
approx 200mm.
3 Circumferentially abrade the cleaned
areas using the abrasion strip.
5 All cables of 30 pair or less require
SCOP’s, if they are required add a second
mark 20-30mm towards the joint opening.
6 Starting at the inner most mark wrap the
SCOP as shown in the photograph.
7 Tape the signed and dated desiccant to
the joint bundle.
8 Wrap and install one liner with fingers in
line with the mark 50mm from the butt. Tape
the centre of the liner and then tape the
fingers down onto the cable. The tape should
not extend more than 5mm onto the cable.
9 Wrap and install the second liner over
the first with the fingers in line with the
50mm mark. Tape the middle together as
shown in the photograph. Tape the fingers
onto the cable, again the tape should not
extend more than 5mm onto the cable.
10 Make a mark 90mm from each end of
the liner then add a second mark
20-30mm nearer to the joint.
11 Measure the distance between the two
outer marks on the cables, this will be the
sleeve length.
12 Using side cutters cut the sleeve to
length. Cut the flap ends at an angle of 45°.
13 Apply the aluminium foils onto the
cables at the inner mark away from the joint.
Apply foils around the SCOP’s in line with the
foils on the cables.
14 Cut the aluminium sheet to the total
length of the installed liners. Wrap the liners
with the aluminium sheet, tape the ends of
the sheet down over the liner fingers as
illustrated in the photograph.
15 Wearing gloves wrap the sleeve around
the liner. Pull the flexible channel over the
rails (Puller 18 may be used for this
operation). Using side cutters cut the
channel, the channel should overlap the ends
of the sleeve by one complete channel
segment.
To reduce the danger of sharp edges
the cut should be angled as shown in
the photograph.
16 Insert any branch-off clips ensuring that
the clips are totally inserted. The sleeve
opening should be proportionally divided
according to the cable diameters. Tape the
cables together to hold the sleeve and clips
in position.
17 Support all cables and sleeve before
shrinking down. Using a ‘C’ nozzle start
heating the sleeve at the centre opposite the
channel slowly working your way to the
channel area making sure the temperature
paint (T.I.) has changed from green to black.
18 Continue shrinking as described in
17 moving progressivery towards one end of
the sleeve. Shrink the transition area in one
go.

19 Press the channel with a blunt tool to
follow the form of the shoulder.
20 Repeat steps 17 to 20 towards the other
end of the sleeve. Wait 15 minutes approx
before cable handling.Tape over the ends of
the channel.
Re-entry Procedure
21 Using the junior hacksaw, cut through
the rail and make circumferential cuts in the
sleeve halfway down the transition on both
ends. Do not cut through the liner.
22 Using a “D” nozzle, gently heat one side
of the centre section of the sleeve, below the
white line and between the circumferential
cuts, until soft. (NB. Do not overheat).
23 Using the tip of a knives chipping, score
along the heated side of the sleeve between
the circumferential cuts, making sure that the
aluminium foil has been scored. Allow to
cool.
24 Use the removal wire, hacksaw or
pincers to cut off the remaining sections of
the channel on the sleeve ends. Do not heat.
25 When cool, using pincers, remove the
sleeve and aluminium sheet from the liner.
26 Remove the cardboard liner.
Re-closure procedure
27 The joint should be re-closed using a
new Kit Repair 11.
Please refer to the re-closure notes on next
page for additional information.

Re-closure Notes
SCOP position
Existing clip
Existing closure end
1. All aluminium foils must be removed from the existing cables, the cables should be cleaned and abraded following steps 2 and 3 on page 1.
2. Existing clips if fitted do not need to be removed.
3. The new liners should be taped down onto the existing closure ends, the tape must not extend onto the cables.
4 All cables of 30 pairs or less require SCOP’s, if SCOP’s where fitted to cables on the original closure they should be positioned as in, fig 1 above.
5. The new sleeve length to be cut should be 200mm longer than the existing closure length. The sleeve when installed must extend beyond each
end of the existing closure ends by 100mm.
6. Measure and mark the cables 100mm each side of the existing closure ends. Add a second mark 20-30mm nearer to the existing closure ends.
If SCOP’s have been fitted carry this mark across to the SCOP’s.
7. Follow steps 12 to 21 on pages 2 and 3.
For cable additions, apply two scops to cable if 30 pr or less as shown in fig. 2 above.
