Cable sheathing,
armouring,
printing &
marking
Sheathing and armouring are
above all defensive: necessarily
so, if the cable is to serve the
ever-higher power demands of
today’s electrical installations.
The “armour” must also protect
itself. If it is nicked, cut, shredded,
or otherwise compromised, the
sheathed bundles of insulated
wires within will be vulnerable to
failure – or worse.
Printing and marking, though less
obviously defensive, belong in
this company.
A misidentified length of cable
– inadequate to its purpose,
potentially hazardous – would be
as unreliable in service as a poorly
fortified length.
Armoured cable must be secure within
its sheath. To the companies reviewed
here, it is equally important that the cable be
known for what it is.
