Our 25.0mm² 4 Core + Earth Orange Circular cable is a large three-phase power cable priced per metre, ideal when a submain or plant supply needs a specific length rather than a full drum. It provides three actives, a neutral and an earth in one heavy-duty circular cable.

The 19/1.35mm stranded copper cores use X-90 XLPE insulation and are accompanied by a 6mm² earth, all within an orange 5V-90 PVC sheath about 25mm in diameter. Rated 0.6/1kV with a 90°C maximum conductor temperature, it is a common size for three-phase submains to factories, commercial switchboards and larger rural or industrial sheds, where load and run length call for more than 16mm².

Key Features

• Cut to Your Length – Sold per metre, so the order matches the run without a costly remnant.
• 25.0mm² Three-Phase Cores – Large conductors for heavy three-phase loads and longer submains.
• Three Actives, Neutral and Earth – Red, white and blue phases with a black neutral and green/yellow earth.
• X-90 XLPE Insulation – Cross-linked insulation designed for 90°C operation.
• 19/1.35mm Stranding – Multi-strand plain annealed copper that is easier to work at terminations.
• 6mm² Earth Conductor – Built into the cable to simplify installation.
• 0.6/1kV Rating – Suited to low-voltage three-phase mains and submains.
• Durable Orange Sheath – A 5V-90 PVC sheath offers robust protection and clear identification.

For heavy three-phase work, the OC2504CE 25.0mm² 4 Core + Earth Orange Circular combines XLPE insulated 19-strand cores, a 6mm² earth and a 0.6/1kV rating in one tough cable. Buying it by the metre makes it easy to match each submain run precisely, so you get the cable you need without paying for spare drum length.
