REMOVAL OF THE CORE INSULATION
A. Compression type contacts (Type TBC-X)
core insulation
1 A. For compression type contacts : remove the core insulation from the conductor for a distance « C » mm
(C = depth of contact bore + 10 mm).
1 B. For mechanical type contacts : remove the core insulation from the conductor for a distance « C » mm
(C = depth of contact bore + 10 mm).
edge of the outer sheath
water sealing mastic (type NGAF)
2 Slightly bevel the edge of the core insulation. Do not sharpen in cone-shape.
3 Thoroughly clean core insulation. Always wipe towards the screen wires.
4 As a protection, wrap a few turns of adhesive tape around the conductor end.
5 Remove field control mastic strip, type MFC, from coated paper. Apply the mastic on the cutback edge of the
semi-conductive screen, covering approximately 5 mm of the extruded semi-conductive screen and 5 mm of the
core insulation. Push the mastic in place while stretching it progressively until both ends overlap and tear-off the
excess mastic. Using the coated side of the paper, squeeze the mastic tightly in place on the step of the
semi-conductive screen.
6 For outdoor applications: Wrap another layer of water sealing mastic (type NGAF). Start taping 25 mm from
the end of the outer sheath over the first mastic layer and the screen wires and continue up to a point 10 mm on
the semi-conductive screen. Make a cone-shape.
INSTALLATION OF THE CABLE REDUCER
1 Lubricate* the indicated area : core insulation, mastic, semi-conductive screen and inner surface of the reducer.
2 Slide the reducer down the cable.
3 Remove the protective adhesive tape from the conductor.
