Built for heavier three-phase work, this 16.0mm² 4 Core + Earth Orange Circular cable comes on a 100 metre roll, with 200m, 250m, 300m and 500m cut lengths available on enquiry. It packs three actives, a neutral and an earth into one tough round cable for submains and large equipment supplies.

Its 7/1.70mm stranded copper cores are insulated with X-90 XLPE and joined by a 6mm² earth under an orange 5V-90 PVC sheath, giving a cable of roughly 21mm diameter. It is rated 0.6/1kV with a 90°C maximum conductor temperature, and its round profile glands cleanly into switchboards and plant. It is a staple size for factories, warehouses, commercial buildings and multi-unit developments.

Key Features

• Full 100m Roll – Suits multiple submains or long three-phase runs, with longer cuts on request.
• 16.0mm² Cores – Generous capacity for heavier three-phase loads.
• Three-Phase Configuration – Three actives and a neutral plus an integral earth.
• 6mm² Earth – Built into the cable, so no separate earth run is needed.
• XLPE Insulated – X-90 cross-linked insulation for reliable performance under load.
• Clear Phase Identification – Red, white and blue actives, black neutral and green/yellow earth.
• 0.6/1kV Rated – Designed for low-voltage mains and submains.
• Robust Orange Sheath – 5V-90 PVC for mechanical toughness and easy identification.
• Approximately 21mm Diameter – A round profile suited to glands and conduit.
