This is an underground secondary distribution cable made of twisted assemblies of alloy 1350 aluminum conductors insulated with black cross-linked polyethylene (XLPE). It is used in various underground applications in secondary distribution circuits.
The conductors are compressed Class B stranded, 1350 series aluminum alloy. The phase conductors and the neutral conductor are cabled together to form a twisted assembly.
