• The seal sleeve.
(4) Put a seal insert on Cable B or Cable C.
(5) Assemble the Cable A end of the splice:
(a) Fold the conductor of Cable A back on itself so that the end of the conductor is aligned with
the end of the insulation.
(b) Push the conductor into one end of the splice so that the end of the conductor is aligned
with the center of the splice.
(c) Crimp the splice.
(6) Assemble the other end of the splice:
(a) At the same time, push the conductors of Cable B and Cable C into the other end of the
splice so that the end of the conductors is aligned with the center of the splice.
(b) Crimp the splice.
(7) Align the center of the seal sleeve with the center of the splice.
(8) Shrink the seal sleeve into position.
(9) Push the shield tube toward Cable B and Cable C so that the rear end of the tube is against the
end of the cable jacket of Cable A.
(10) Attach the end of the shield tube to the shield of Cable A:
(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 the small solder sleeve toward the end of the cable until the rear edge of the solder
ring is 0.10 inch from the end of the cable jacket.
(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 shields of the Cable B and Cable C:
(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 jackets
of the Cable B and Cable C.
(c) Twist the end of the shield tube down so that the end of the tube is tight against the shields
of the cables.
(d) Push the large solder sleeve toward Cable B and Cable C until the rear edge of the solder
ring is 0.10 inch from the end of the cable jacket.
(e) 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.
(12) Push each seal insert toward the splice until the forward end is against each solder sleeve on
each side of the splice.
(13) Align the center of the outer sleeve with the center of the seal sleeve.
NOTE: On each end of the splice assembly, the outer sleeve should make approximately a 1.0
inch overlap with the seal insert.
