cut the insulation without damaging the layers
beneath.
If the instructions are not followed correctly,
or if any of the insulation layers or the copper
foil are incorrectly cut, then the integrity of
the lightning protection is affected.
Refer to Figure 21 on page 36 for the
following instructions (1 to 11).
1. At a distance of 600 mm (23 5 ⁄
8
in.) from
the end of the cable, carefully cut a shallow
notch into the black outer insulation no
deeper than 1 mm, (
3 ⁄
64
in.). Then, using
the insulation cutting tool, cut around the
circumference of the black outer insulation
until the copper screen underneath is
exposed, (see photo 3).
2. Using a knife, carefully cut the outer
insulation of the cable to a depth of no
more than 1 mm (
3 ⁄
64
in.), for the full
600 mm (23 5 ⁄
8
in.), in the direction of the
end of the cable. Be sure not to cut so deep
as to expose or damage the copper layer
underneath. Starting from the end of the
cable, carefully remove the outer insulation
and discard.
3. Carefully clean up the friction cut,
removing any burrs for a neat finish.
4. Fit the roll spring 20 mm ( 6 ⁄
8
in.) from the
end of the outer insulation over the exposed
copper tape.
5. From the end of the cable, remove the
copper tape up to the roll spring, exposing
the black semi-conductive material by
unrolling, then tearing the tape up and back
over the edge of the roll spring at about a 45˚
angle. (If necessary, carefully cut about 6 mm
of the copper tape up against the roll spring
with a knife and then tear over the spring).
The Insulation Cutting Tool uses
friction to cut into the sheath and is
less likely to damage the layers
underneath than using a knife. When
the instructions call for the knife to be
used, be sure not to cut any deeper
than instructed.
