Construction

Conductors:

This is an aluminum conductor cable. The conductor is designed in two forms: either concentric strand or compressed. The stranded type tends to be more flexible compared to the compressed series of aluminum conductors. The 1350-H19 series of compressed aluminum conductors are suitable for applications where flexibility is overlooked and cable rigidity is guaranteed.

Insulation:

Aluminum 600V URD cable has black resistant cross-linked polyethylene (XLP) insulation. The conductors are normally cabled together with XLP insulated aluminum ground or bare copper ground and covered with reinforced binder tape. XLP insulation is tough and resistant to impact, abrasion, chemicals, acids, oils, industrial solvents, and changes in weather.
