This 25mm² XLPE Four Core mains cable is a heavy-duty copper power cable sold by the metre, made for three-phase mains and submains where a separate earth is run. It carries three actives and a neutral in one round cable, with no integral earth, so you can order exactly the length the installation requires.

The stranded plain annealed copper cores are insulated with X-90 XLPE and protected by a black 5V-90 PVC sheath, giving a cable of about 27.5mm diameter rated 0.6/1kV with a 90°C maximum conductor temperature. This style of XLPE mains cable is widely used for low-voltage underground distribution and consumer mains, installed enclosed or unenclosed, in conduit, buried direct or in ducts where it is not subject to mechanical stress.

Q. Does this cable include an earth?
A. No. This is a four core cable with no earth, made up of three actives and a neutral. A separate earth conductor must be installed where required by AS/NZS 3000.

Q. Is it priced per metre?
A. Yes. The price is per metre. A cutting fee or drum charge may apply for non-standard lengths.

Q. Can it be installed underground?
A. Yes. XLPE mains cable of this type can be installed in conduit, in ducts or buried direct where it is not subject to mechanical stress. Always follow AS/NZS 3000 and your local network's service rules for depth, enclosure and marking requirements.

Q. How is this different from 25mm 4 Core + Earth orange circular?
A. This cable has no integral earth and a black sheath, while 4 Core + Earth orange circular includes an earth core within an orange sheath. Choose based on whether your installation design calls for a separate earth conductor.
