C. Sealed Splice Configurations for Unshielded Wires and Cables for High Temperature - One Wire
to One Wire - Tape, Sleeve
For the conditions that are applicable for:
• The repair of a wire or a cable with a splice, refer to Subject 20-10-13
• The selection of the correct sealed splice configuration, refer to Paragraph 1.C.
Refer to Figure 97.
(1) Find the CAU of the conductor.
Refer to Paragraph 1.D. for the procedure to calculate the CAU of the conductor.
(2) If the CAU of the conductor is less than the minimim CAU for the butt splice, increase the CAU of
the conductor.
Refer to:
• Table 15 for the minimum CAU of the butt splice
• Paragraph 2. for the applicable conditions and procedures for the increase of the CAU.
(3) Make a selection of a butt splice from Table 15.
Make sure that the splice has the smallest CAU range that can accept the total CAU of the
conductor.
(4) Find the crimp barrel size of the splice from Table 15.
(5) Make a selection of a crimp tool from Table 46.
(6) Make a selection of a Temperature Grade D insulation tape from Table 52.
(7) Make a selection of a Temperature Grade D heat shrinkable sleeve from Table 51.
