TECK90 is a flexible, interlocked aluminum armoured cable having an inner PVC jacket over the insulated conductors as well as outer PVC jacket over the armour. TECK90 is CSA-approved for open and concealed wiring, direct burial and for use in Class I, II & III hazardous locations. On single-conductor cables, the bonding conductor is applied helically around the phase conductor.

Multi-conductor constructions are available in 600 and 1000 volt ratings in sizes 6 AWG to 750 kcmil (13.3 to 380 mm2 ) in NUAL®. In multi-conductor construction in sizes 1 AWG and larger, phases are identified with the words one, two and three in the print legends. In sizes smaller than 1 AWG colour coding is used for phase identification. All identified neutral conductors are white. All Alcan Cable TECK90 cables are filled to round using non-hygroscopic filler ensuring uniform concentricity which eases pulling. All Alcan Cable TECK90 jackets have metre markings which greatly ease measuring and cutting lengths. Prior to shipping from the manufacturing facility the accuracy of the markings is verified with gauges calibrated to international standards. Alcan has chosen not to mark single conductor cables H.L., as single conductor armoured cables should not be used in hazardous locations.
