Also Known As: 

4/0 XHHW-2 Copper Building Wire, 4/0 XHHW Cable, 4/0 XHHW Service Wire, 4/0 XHHW Copper Wire.

Conductor:

The cable has an annealed bare copper conductor (solid or concentrically stranded). The conductor has excellent electrical conductivity and excellent resistance to moisture. The conductor also has excellent resistance to compression, pressure, and heat.

Insulation:

The cable is insulated with a cross-linked polyethylene jacket (XLPE) that serves as a protective armor to the conductors. It is flame-retardant and resistant to abrasion, corrosion, moisture, dryness, chemicals, and heat.
