Product Overview
ACWU90 is a versatile aluminum-conductor armoured cable designed for robust electrical distribution in demanding environments. Certified to CSA standards (C22.2 No. 174 & No. 51) and CUL-listed, it combines corrosion resistance, mechanical protection, and flame-retardant properties for reliable power transmission in wet/dry, exposed, or buried applications.
Key Applications
-
Exposed Wiring: Weather-exposed installations, wet/dry locations.
-
Concealed Wiring: Ducts, conduits, and service entrances (above/below ground).
-
Cable Trays: Ventilated, non-ventilated, and ladder-type trays.
-
Direct Burial: Earth burial without additional conduit.
-
Industrial/Commercial Use: Service entrances, feeders, and branch circuits.
