Consac Cable Joints

These type of cable joints must only be installed by Trained & Competent Jointers using the approved and correct Consac cable jointing tools.

Consac Cable Construction

1.  Extruded PVC or polythene oversheath cable jacket
2.  Layer of bitumen containing corrosion inhibitor
3.  Extruded smooth aluminium sheath
4.  Paper belt insulation
5.  Paper core insulation
6.  Solid aluminium conductors

How To Remove The Aluminium Sheath From Consac Cable

1. Mark the aluminium sheath at the cable joint centre and make an additional two extra marks at 60 degrees to form an arrow – this arrow MUST point to the cable jointer
2. Select the correct cutting wheel for the Consac sheath stripping tool according to the cable cross sectional area. The 45 thousands of an inch cutter is used for 70mm to 120mm cable, the 70 thousands of an inch cutter is used for 150 to 240mm cable
3. Set the angle of the Consac sheath cutting tool to 60 degrees, using the front control wheel and scale
4. Using the rear pressure control wheel, open then close the tool onto the first of the 60 degrees marks. Apply the light pressure then rotate the tool outward along the cable until it butts up to the PVC sheath edge, this should occur at tool bottom dead centre
5. Repeat this operation, moving the cable jointing tool forward and backward along the cable, gradually increasing the pressure using the rear wheel. Continue this process until scuff marks from the shoulders of the cutting wheel appear along the edges of the cut, then stop
6. Remove the cable cutting tool and re-set the cutter angle to 60 degrees on the opposite hand. Re-fit the tool and repeat operations 4 & 5. Remove the tool on completion
7. At the point where the two tool cuts join, use the edge of a six inch half round file to deepen the cut until the underlying papers begin to appear. The flat side of the file must point towards the inside of the arrow
8. Using a hammer and pliers lift the point of the arrow – wearing insulating gloves unpeel the aluminium sheath from the cable until the ends of the cut are reached. The sheath should now appear as shown in the illustration pointing away from the cable jointer
9. Fit PVC binders at the points where the underlying papers are to be terminated
10. Bear the cut part of the sheath flat with a pair of wooden beaters
11. Holes can be punched in the aluminium sheath where required using a special purpose hole punching tool

Note: Using approved cable cleaning wipes ensure that the prepared Consac cables are cleaned thoroughly and all dirt, debris or contaminants are removed.
