Round 3-core concentric cable. Compact assembly for three-phase underground service. AS/NZS. XLPE, UV stabilized.
Application
AS/NZS concentric round cable (6mm² / 3-core) for low-voltage underground service and sub-main distribution. Three concentric arranged copper conductors (3 phases), XLPE insulated, PVC/PE sheathed. Suitable for direct burial or duct installation in residential/commercial compounds, street lighting feeders, and general LV underground wiring.
Core Strengths
Single core armoured cable for street lighting feeders is costly and less balanced. Our 3-core 6mm² concentric cable provides compact round assembly for underground service. AS/NZS. XLPE insulation, UV stabilized. Direct burial/duct.
Standard
IEC227, BS6004, ANSI
Construction
☉〉 Phase conductor: Copper (or aluminum)
☉〉 Insulation: XLPE or PVC
☉〉 Communication conductor(s): Insulated for signaling
☉〉 Fillers: For roundness and stability
☉〉 Wrapping tape: Over core assembly
☉〉 Inner sheath: Extruded layer
☉〉 Rip cord: For easy outer sheath removal
☉〉 Concentric layer: Copper neutral/earth
☉〉 Outer wrapping tape & outer sheath: Protection
Features
☉〉 Integrated communication conductor enables combined power and signal transmission
☉〉 Concentric neutral provides earth continuity and fault return path
☉〉 Round design with fillers ensures uniform electrical field and mechanical strength
☉〉 Rip cord allows fast, damage-free outer sheath stripping
☉〉 Outer sheath offers weather, moisture, and abrasion resistance
