PART D - TENSION BRIDGE
33. When it is time to connect two cables together, you need to reduce the
amount of tension on the connectors.
Heavy strain can eventually cause a
disconnect within the connector between the wires and the pins.
To
eliminate this possibility, you should install a tension bridge in the
cable. This also provides slack to permit access to the cable for testing
purposes.
34.
Construct a tension bridge as follows:
a. Cut a 6-foot piece of marline twine or field wire.
b. Loop the cable at the connectors as shown in 1 in Figure 2-4.
c. Make the loop approximately 10 by 20 inches wide, 2 in Figure 2-4.
d. Begin the basket hitch tie using a clove hitch tie with the twine or
field wire, one foot from the center of the loop, 3 in Figure 2-4.
e. Complete the basket hitch tie in the center of the loop, 4 in Figure
2-4.
f. Half square knot.
g. Install a basket hitch tie on the other cable in the same manner and
tie the two ends in a square knot, 5 in Figure 2-4.
h. Use the remainder of the twine or wire to support the loop, 6 in
Figure 2-4.
