Application

Used for secondary distribution and underground service at 600 volts or less, either direct burial or in ducts.

Construction

Conductors are stranded, compressed 1350-H19, H16, or H26 aluminum, insulated with cross-linked polyethylene. Neutrals are triple yellow extruded stripe.

 

         

          

Color: distribution cable is black.

Description: Underground Secondary Distribution Cables are twisted assemblies of aluminum alloy 1350 conductors insulated with cross-linked polyethylene. This underground electrical wire is used in various underground applications in secondary distribution circuits at up to 600 volts.

Conductor: Compressed Class B compressed stranded, 1350 series aluminum alloy.

Insulation: Black cross-linked polyethylene (XLPE)

Assembly: Phase conductors and neutral conductors are cabled together to form a twisted assembly.

Applicable Standards: – UL 854: Service Entrance Cables

– ICEA S-105-692 Standard for 600 Volt Single Layer Thermoset Insulated Utility Underground Distribution Cables.
