Nexans MONOi Single Core Heat Shrinkable Termination

Product Information

The MONOi/MONOe-1 is an indoor/outdoor single core heat shrinkable termination used for solid insulation cables withXLPE-HEPR insulation. It is suitable for cables with a voltage rating of up to 12 kV. The termination assembly includes a red mastic MBA, copper screen wires, a semi-conductive layer, a lug, a stress relief mastic pad MACD, and a red tube GT12.

Product Usage Instructions

1. Prepare the cable by cutting the exceeding length.
2. Remove the outer sheath for the specified length (L) as mentioned in the table. Abrade the outer sheath for 100 mm and clean it with solvent.
3. Apply a layer (20% overlap) of red mastic MBA for a length of 30 mm.
4. Fold back the copper screen wires and temporarily fix them at 150 mm from the cut sheath using PVC tape.
5. Remove the semi-conductive layer, leaving 40 mm out of the outer sheath without damaging the insulation.
6. Bare the conductor for the specified length (C) based on the type of lug being used.
7. Position the lug and either crimp it or break the screws in case of a bolted lug, following the manufacturer’s instructions.
8. Apply a layer of red mastic MBA (20% overlap) over the screen wires, covering the previous layer of MBA. Fill the cavities over the lug with red mastic MBA.
9. Wrap the exposed conductor with red mastic MBA, stretching it until reaching the lug barrel diameter. Also, wrap the same mastic around the lug barrel.
10. Remove the protective paper from the MACD pad. Apply the stress relief mastic pad MACD, starting from the cut outer sheath.
11. Slide the red tube GT12 (stress control + insulation) until the top edge of the red mastic MBA applied over the cable lug.
12. Start heat shrinking from the top downwards.
13. Remove the PVC tape previously applied on the screen wires and split them into two parts. Wrap the wires at the bottom of theshrunk tube, making a ring. Twist the screen wires, cut straight, and either crimp or screw the grounding lug.
14. For outdoor termination only, slide the antitracking sheds atspecified distances from the bottom edge of the shrunk tube andheat shrink them.
15. Dispose of all waste according to environmental regulations.

ASSEMBLY OF THE TERMINATION

1. Prepare the cable and cut the exceeding length.
2. Remove the outer sheath for the length “L” (“L” see the table).
   • Abrade the outer sheath for 100 mm and clean with solvent.

TYPE| OUTDOOR TYPE
SECTION RANGE (mm2)| 25 ÷ 95| 70 ÷ 240| 95 ÷ 300| 185 ÷ 400| 400÷ 630| 630 ÷ 1000| 800 ÷ 1200| 1200 ÷ 1600
L (mm)| 450| 450| 450| 450| 450| 450| 450| 500

1. Apply a layer (20% overlap) of red mastic “MBA” for 30 mm length.
2. Fold back the copper screen wires and fix them temporarely at 150 mm from cut sheath with some turns of pvc tape.
3. Remove the semi-conductive layer leaving 40 mm out of the outer sheath taking care not to damage the insulation.
4. Bare the conductor for the length “C” (“C”= inside depth of lug) for bolted lug or “C+5mm” in case of compression lug.
5. Position the lug and crimp it or break the screws in case of bolted lug following the manufacturer’s instructions.
6. Apply a layer of red mastic “MBA” (20% overlap) over the screen wires covering the previous layer of “MBA”. Fill the cavities over the lug with red mastic “MBA”.
7. Wrap around the exposed conductor the red mastic “MBA” stretching it, wrap till reaching the lug barrel diameter. Wrap also the same mastic around the lug barrel.
8. Remove the protective paper (the one with the printing) from the MACD pad. Apply the stress relief mastic pad “MACD”, lightly stretched, starting from the cut outer sheath.
9. Slide the red tube “GT12” (stress control + insulation) till the TOP edge of red mastic “MBA” applied over the cable lug.
10. Start heatshrinking from the top downwards.
11. Remove the PVC tape previously applied on the screen wires and split them into two parts; wrap the wires at the bottom of shrunk tube (one round) making a ring. Twist the screen wires, cut straight and crimp OR screw the grounding lug.
    • INDOOR TERMINATION IS FINISHED
12. ONLY FOR OUTDOOR TERMINATION
    • Slide the first antitracking shed at 160 mm from the bottom edge of shrunk tube and heatshrink.
    • Slide the remaining shed and heatshrink. Different number of sheds and tail lengths available upon request.
