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.

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.

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.
