PART A- SPLICING WD-1( )/TT
1.
The strongest part of a communications link is its weakest point, and at times you will find that
this will also apply to your field wire lines. This section will cover splicing and repairing field wire.
You will learn the procedures to repair WD-1( )/TT first since it is the easiest to use and most common
wire found in units today.
2
The expedient splice will be used because all repairs done to a line in the field have to be an
expedient method of restoring communications. Expedient means suited to the circumstances or
situation; a means to an end; a device used in an emergency; makeshift. The expedient splice fits all
those definitions.
3.
You have to learn the correct procedure to make an expedient splice.
a.
Cut the ends of the wires even; straight across. (See Figure 2-1.)
b.
Separate the conductors.
c.
Cut one conductor of each pair 6 inches shorter than the other. Use the length of the TL-
13A to measure. This is necessary so that the bare wires do not touch. (See Figure 2-1.)
Figure 2-1. Conductors staggered for splicing.
d.
Remove the insulation. Remove 1 to 2 inches at a time being careful not to cut any of the
wires. If you do cut any wires, start over. Keep 1/2 inch insulation on the end of the wire to keep the
individual wires together. (See Figure 2-2.)
