5. Once the wedge is inserted, use a hammer and drift pin or other appropriate tool to seat
the wedge by hitting on the triangular end of the casting. Several hits should be made to
seat the wedge.
6. A heavy hex nut (PN-3908G for 1” fitting) or heavy square nut (PN-4959G for 3/4” fitting)
has to fit inside the housing. Once the wedge has been seated, check to make sure the
nut will fit. If it will not, reseat the wedge.
7. After the wedge is properly seated, one (1) wire of the cable must be bent over the end of
the wedge.
8. Insert the appropriate hex nut in the housing.
9. Place the left-hand threaded stud (PN-3537G for 1” fitting or PN-105204G for 3/4” fitting)
or right-hand threaded stud (PN-3536G for 1” fitting or PN-105205G for 3/4” fitting) in the
housing and into the nut. Screw the stud into the nut until it will not go any further. A
minimum of two threads of the stud must show beyond the nut.
10. With the field applied fitting attached, follow the steps for a “Factory Applied Fitting” section
to connect the two cables with a turnbuckle.
Torpedo Cable Splice
When two cable ends are spliced together other than where spliced with a turnbuckle, a Torpedo
Cable Splice can be used. The Torpedo Cable Splice (PN-4099G) assembly is made up of two
(2) housings, one of which has threads on it, a threaded ring, and two (2) triangular wedges. See
Figure 8.
Warning
:
The distance from the torpedo splice to any other fitting must be 100’
[30 m] or greater.
Perform the following steps to complete a splice:
1. Ensure that the cables have a clean square cut by using a saw with an abrasive blade or
an electric band saw.
2. Insert the cut end of the cable through the triangular end of the threaded Torpedo fitting.
3. Separate one of the wires from the others by bending it out of the way.
4. Cut the remaining twenty (20) of the twenty-one (21) wires off about 1/2” to 3/4” (13 mm
to 19 mm) from the end of the cable. Care should be taken to not nick the separated wire.
5. With the wires cut off, separate the cable with two flathead screwdrivers and insert the
tapered triangular wedge (PN-4199B).
6. With the wedge inserted into the cable, drive the wedge into the housing until the twenty
(20) wire strands are flush with the end of the housing. Bend the one (1) extended wire
of the cable over the end of the wedge.
7. On the other cable, place the threaded ring on it so the threads inside the ring are towards
the end of the cable.
8. On this same cable, follow Steps 1-7 to assemble the cable in the fitting.
9. Place the two (2) Torpedo Cable pieces together and connect them with the threaded ring.
Tighten the connection with a pipe wrench(s), ensuring no more than two threads are
shown after the connection.
Note:
No more than two threads should be shown after the connection.
