This quadruplex underground secondary distribution (URD) cable is a twisted assembly of three 4/0 AWG phase conductors and one 2/0 AWG neutral conductor. The conductors are alloy 1350 aluminum. The phase and neutral conductors are cabled together to form the twisted assembly.
Each conductor is compressed Class B stranded and insulated with black cross-linked polyethylene (XLPE). The cable is used in underground applications in secondary distribution circuits, including direct burial.
