(5) Assemble the Cable A side of the splice configuration:
(a) Put the conductor of Wire A1 in one of the splices so that the end of the conductor is aligned
with the center of the splice.
(b) Crimp the splice.
(c) Put the conductor of Wire A2 in the other splice so that the end of the conductor is aligned
with the center of the splice.
(d) Crimp the splice.
(6) Assemble the Cable B side of the splice configuration:
(a) Put the conductor of Wire B1 in the open end of the splice that has Wire A1 of Cable A so
that the end of the conductor is aligned with the center of the splice.
(b) Crimp the splice.
(c) Put the conductor of Wire B2 in the open end of the splice that has Wire A2 of Cable A so
that the end of the conductor is aligned with the center of the splice.
(d) Crimp the splice.
(7) Align the center of each seal sleeve with the center of each splice.
(8) Shrink each sleeve into position.
(9) Push the shield tube toward Cable B until the forward end of the tube is against the end of the
cable jacket of Cable B.
(10) Attach the end of the shield tube to the shield of Cable B:
(a) Twist the end of the shield tube down so that the end of the tube is tight against the shield of
the cable.
(b) Push one of the solder sleeves toward Cable B until the rear edge of the solder ring is 0.10
inch from the end of the outer jacket of the cable.
(c) Apply heat to the center of the solder sleeve until the solder melts and flows into the shield
tube and the shield of the cable.
(11) Attach the remaining free end of the shield tube to the shield of the Cable A:
(a) Pull the shield tube across the splice so that it is tight.
(b) Remove the length of the shield tube that makes an overlap with the end of the outer jacket
of the Cable A.
(c) Do Step 16.D.(10) again.
(12) Align the center of the outer sleeve with the center of the seal sleeves.
NOTE: On each end of the splice assembly, the outer sleeve should make approximately a 1.0
inch overlap with the cable jacket.
(13) To shrink the outer sleeve into position:
(a) Apply heat from the center of the sleeve toward one end of the sleeve until the longitudinal
line cannot be seen.
(b) Apply heat from the center of the sleeve toward the other end of the sleeve until the
longitudinal line cannot be seen.
