The 4/0-3 W/GRND XHHW-2 Teck 90 Type MC cable consists of insulated Class B stranded bare soft copper conductors wrapped in an aluminum interlocked armor.  The soft copper is an annealed copper product that offers more flexibility without compromising the copper’s powerful conductive properties.  The copper conductors are insulated with a cross-linked polyethylene (XLP) insulation, which adds mechanical strength to the cables while protecting the conductors from corrosion.  The insulation on each conductor is color coded for identification.  The assembly includes an uninsulated grounding conductor which is made of Class B stranded copper.  The grounding conductor ensures steady conductivity over the life of the cable.  Fillers and binder tape are used to firmly set the assembly of conductors in place.  A heat, flame and moisture-resistant inner jacket of polyvinyl chloride (PVC) is the inner layer of the exterior jacket.  Covering the PVC inner jacket is a rigid interlocked aluminum armor which protects the conductors from being jarred or interfered with by outside objects.  The aluminum armor bears a PVC jacket that is also resistant to heat, flame and moisture. 

The 4/0-3 W/GRND XHHW-2 Teck 90 Type MC cable can be used in wet or dry locations.  The wide-diameter cable can be installed in exposed or concealed areas in indoor or outdoor applications where maximum carrying capacity is required.  The cable’s rugged exterior makes is a suitable option for use in harsh climates or in hazardous locations.  Common uses for this cable are for lighting, power, and control circuits in mills, processing plants, mines, commercial centers, refineries, mines, generating stations, chemical plants and industrial plants.  The cable can function continuously between temperatures of -40°C and 90°C.  Underwriters Laboratories lists the cable capable of transmitting up to 600 volts.
