and reduce the overall drive performance. These cables are not
recommended.
Armored Cable
Cable with continuous aluminum armor is often recommended in drive
system applications or specific industries. It offers most of the advantages
of standard shielded cable and also combines considerable mechanical
strength and resistance to moisture. It can be installed in concealed and
exposed manners and removes the requirement for conduit (EMT) in the
installation. It can also be directly buried or embedded in concrete.
Because noise containment can be affected by incidental grounding of the
armor to building steel when the cable is mounted, we recommend that the
armor cable have an overall PVC jacket. For details, see Chapter 2, “Wire
Types” in Wiring and Grounding Guidelines for Pulse Width Modulated
(PWM) AC Drives, publication DRIVES-IN001.
Interlocked armor is acceptable for shorter cable runs, but continuous
welded armor is preferred.
Best performance is achieved with three spaced ground conductors, but
acceptable performance for drives below 200 HP is provided by way of a
single ground conductor.
