vi) Snagged Wires and Crushed or Flattened Strands:
Check for snagged wires and crushed or flattened stands. These conditions appear when the cable has
been pulled around corners or caught between two heavy objects. See Fig 6k. Remove from service
and return to the factory for re-work.
vii) unlaying and Bird-Caging:
Check for unlaying and bird-caging of strands. This condition appears as the formation of gaps, loops
and excessive clearance between strands. See Fig. 6l. If this appears, remove the unit from service and
return to the factory for re-work.
viii) Kinks and Bends:
Check for kinks and bends in the cable. See Fig. 6m. kinks and bends are created when a loop forms
in a slack cable and then it is pulled tight without the loop uncoiling. Remove from service if kinks or
bends are formed in the cable and return to the factory for repair.
ix) Heat Damage, torch Burns or electric Arcs:
Check for examples of heat damage, torch burns or electric arc strikes. Localized discoloration, fusing
or melting indicate this type of damage. If this is found, remove the unit from service and return to the
factory for repair.
