2. Determine jacket cutback; mark cable.
Cutback must be long enough to allow positioning of insulated conductors
without violating the bend radius (usually 10 times the diameter of the
cable) and fit within the min/max dimensions shown in Table 2.
*Note: If a sealing boot is to be used, at least 4" (102mm) of jacket must be
visible extending from the conduit opening.
Table 2:
Voltage Class
5 & 8kV
15kV
25kV
35kV
**If greater length is required, order bulk tubing.
3. Remove outer jacket.
Remove the outer jacket (and/or armor) and any filler or bedding tapes
around all three phases to the mark made in Step 2.
Note: Do not cut into the shielding layer or phase insulation.
4. Position rejacketing tubes.
If using UniShield cable, discard rejacketing tubes and go to Step 7.
Place one rejacketing tube (larger diameter) over each phase. Bottom of
tube should be within 1" (25mm) of the jacket cutback.
5. Shrink rejacketing tubes in place.
Shrink in place beginning at the cable jacket end. Work the torch around
each tube and to the end of the phase with a smooth brushing motion to
ensure even shrinkage.
