1.The installation site should be free from dust, dry and ventilated.

2.Check whether installation tools and terminal accessories are complete. 

3.Check whether cable accessories match the cable correctly. 

4.Measure 760mm from the cable end and strip off the cable outer sheath.

5.Keep 30mm of steel armor at the bottom and strip off the rest. 

6.Leave 20mm of inner sheath at the root, strip off the remaining inner sheath of the cable and the filler and be careful not to scratch the cable's copper shielding layer.

 7.Separate the three phases and wrap the copper shield at the end of each phase cable with PVC tape.

9.Embed the copper shield grounding wire into the three-phase bifurcation of the cable with a triangular cushion cone, divide the grounding wire into three strands and solder each strand firmly to the copper shielding layer, then fix the grounding wire to the steel armor with a constant force spring and solder firmly, wrap the constant force spring with PVC tape, and wrap filler tape for sealing.

11.Keep 60mm of copper shield upward from the branch sleeve and cut off the rest; make phase identification with PVC tape respectively.

12.Leave 20mm of the semi-conductive layer upward and cut off the rest; be careful not to damage the main insulation layer when stripping the semi-conductive layer.

13.Polish the surface of the insulation layer with fine sandpaper and be careful not to polish the semi-conductive layer.

14.Clean the surface of the insulation layer toward the semi-conductive layer with cleaning paper.

15.Apply silicone grease evenly on the surface of the insulation layer.

16.Slide the stress tube over to overlap 20mm of the copper shield and heat it to shrink.

17.Slide the insulation tube over to overlap the finger end of the breakout boot by 20mm, heat and shrink evenly from bottom to top; if the insulation tube is too long, cut off the excess after cooling.

18.According to the terminal hole depth plus 5mm, cut off the main insulation of each phase at the top

19.Insert the cable lugs and crimp them according to the national standard, and file down the edges, corners and burrs. 

20.Wrap sealant around the cable lug crimping area to fill the gap between the insulation layer and the lug as well as the lug indentation.

21.Slide the sealing tube over and fix it by heat shrinking. 

22.Slide the marker tube over and fix it by heat shrinking.

23.Slide the three-hole rain skirt over to above the breakout boot and heat it to shrink. Then slide the single-hole rain skirt over and heat it to shrink; the distance between rain skirts is 140mm, with two rain skirts for each phase.
