Concentric Cable

Application

Aluminum/copper concentric cable used in service emtrances replacing low voltage bundled cables. Also suitable for sub main distribution and particularly used within high-rise buildings and street lighting systems. These cables offer high resistance to aging, abrasion,moisture,chemicals,oils and acids and afford protection of phase conductors against external ingress.

It covers cricular and falt, single, twin, three or four XLPE insulated conductors with a concentric conductor over the assembly of cores, rated 0.6/1KV, for ues in aerial, direct burial, conduit, open tray and underground duct installations.

Construction

• Conductor：Stranded aluminum alloy AA8000/ copper wires class B according to ASTM B231 and UL 854
• Insulation:XLPE(Cross-Linked-Polyethylene),
   Color black for bipolar cable
   Color black, blue and red applied for more than one phase core cable
• Concentirc Conductor:Single layer of aluminum wires AA8000/ copper wires served as the neutral conductor, equal to the equivalent AWG size of the power conductor
• Separator Tape:A separator tape is applied overtop the helically applied neutral conductor wires.
  The tape acts as a reinforcing bedding for the PVC jacket.
• Sheath: A PVC jacket is extruded overtop of the cable assembly.

Characteristics

• Voltage Rating(Uo/U):600/1000V
• Temperature Rating：-40℃ to +90℃
• Minimum Bending Radius: 8 x overall diameter
• Sheath Color: Black

Standards

ASTM B; ASTM B193; UL 44; UL 854; BS 7870; IEC 60502

Specification

Delivery

The packaging style of wires and cables including coil packaging, reel packaging, wooden drum packaging and iron-wood drum packaging, usually concentric cable used reel packaging, wooden drum packaging and other packaging style. The packaging style is mainly based on the length and weight of the cables , we customize the satisfactory packaging method based on customers’ needs.
