Interlocked armored cable consists of insulated conductors, which is made up of cross-linked polyethylene and twisted with an un-insulated ground wire. The twisted core is covered with a PVC jacket, then covered with either interlocked aluminum or galvanized steel, and covered with a PVC jacket over the armour. Interlocked armored cable is used in petro-chemical, pulp & paper, and other industrial application environments. Interlocked armored cable can be used in open and concealed wiring, direct burial, and in hazardous locations.
