1
Cut the cable
5
mm from the centerline of the bushing.
2
Remove the outer sheath for a distance of
130
mm.
3
Remove the copper tape screen and fabric tape to a point
25
mm from
the outer sheath and secure it with a wrap of adhesive tape.
Do not remove the graphite varnish at this stage.
4
Cut longitudinal split(s) in the outer sheath to a point
40
mm from the edge.
5
Using a blunt tool, make a slight funnel of the outer sheath to fit the earthing device underneath the sheath.
6
Install the earthing device underneath the outer sheath. Have it protruded by maximum
20
mm.
7
Cleat the outer sheath using the stainless steel straps. Twist straps twice around the cable and fold back the ends
to avoid sharp edges.
8
Apply 2 layers of semi-conductive tape, (50% stretch, 50% overlap), as follows: start taping on
the metal straps (ensure the splits are covered), up to a point
40
mm behind the outer sheath. Without cutting the
tape, apply a second layer back to the start.
9
Remove the core insulation from the conductor for a distance of
30
mm.
a
Using an appropriate solvent thoroughly remove the graphite coating up to the semi-conductive
tape.
z
Slightly round-off the edge of the core insulation.
Do not sharpen in cone-shape.
