• The shield sleeve material.
NOTE: If it is necessary, the strands at the end of the shield sleeve material can be moved apart
to make it easier to put the shield sleeve material on the cable.
(9) Make a selection of an applicable Temperature Grade B conductor splice configuration for one
wire to one wire. Refer to Paragraph 9.A.
(10) Assemble each conductor splice. Refer to the applicable procedure given in Paragraph 9.A.
(11) Assemble the end of the shield splice opposite the end with the shield sleeve material.
(a) Move the outer ferrule on the shield sleeve material.
(b) Move the strands of the shield apart and make them straight.
(c) Align the forward end of the inner ferrule with the end of the outer jacket.
(d) Fold the strands of the shield back on the inner ferrule to make the strands of the shield
symmetrical around the circumference of the ferrule.
(e) Align the end of the shield sleeve material with the end of the strands of the shield that are
folded back.
(f) Align the rear end of the outer ferrule with the rear end of the inner ferrule.
Make sure that:
• The outer ferrule goes around the shield sleeve material
• The rear end of the outer ferrule does not extend farther than the rear end of the inner
ferrule
• The rear end of the outer ferrule is a maximum of 0.06 inch from the rear end of the
inner ferrule.
(g) Crimp the ferrules.
(12) Do Step 10.H.(11) again to assemble the other end of the shield splice.
Make sure that the shield sleeve material is pulled tightly before the ferrules are crimped.
(13) Remove the shield and the shield sleeve material that extend farther than the rear end of the
inner ferrule on each end of the shield splice.
(14) Tightly wind a layer of the tape on the splice assembly that:
• Starts 0.50 inch ±0.25 inch farther than the rear end of the ferrule at one end of the splice
• Stops 0.50 inch ±0.25 inch farther than the rear end of the ferrule at the other end of the
splice
• Makes a 50 percent overlap.
(15) Tightly wind a second layer of the tape on the splice assembly that:
• Starts 1 inch minimum farther than where the first layer of tape stops
• Stops 1 inch minimum farther than where the first layer of tape starts
• Makes a 50 percent overlap.
(16) Assemble a lacing tape wire harness tie on each end of the splice assembly approximately 0.25
inch from the end of the tape. Refer to Subject 20-10-11.
Make sure that the Temperature Grade of the lacing tape is Temperature Grade B or higher.
