Section III.
SHIELDED CABLES
8-8. GENERAL
Some high-voltage or high-current electrical circuits are shielded to prevent the
circuit from inducing a current in a parallel circuit.
The shield is connected to
ground which will stop current from escaping or entering the conductor from any
source other than its own circuit.
Shielded cables should be replaced whenever
possible.
Communications cables are covered in chapter 15.
8-9.
SHIELDED CABLE DAMAGED
General Information:
Repairs are possible if replacement cables are not available. Care must be taken
so the shield is not connected to the conductor.
Limitations:
o Possible radio frequency interference (RFI)
Personnel/Time Required:
o 1 soldier
o 20 - 40 minutes
Materials/Tools:
o Solder, rosin-core
o Tape
o Soldering iron
Procedural Steps:
Option 1:
Coaxial Cable.
1.
Cut back coaxial cable cover 3 inches from each wire end.
2.
Cut back woven shield and inner conductor insulation on one wire 2 inches from
the end.
3.
On the other wire, unweave the shielding and remove the inner conductor
insulation 2 inches from the end.
4.
Splice the broken wires by twisting and soldering. If soldering iron is not
available, lay wires side by side and wrap with a busswire.
