Project procurement guide.
5x70 mm² and 3x70+2x35 mm² describe different core arrangements. The first has five equal nominal conductor areas; the second has three 70 mm² cores and two 35 mm² cores. They must not be substituted solely because both contain five conductors.
Specify every core when ordering 5 core 70mm2 XLPE power cable. The description normally indicates five cores of the stated area, but the approved drawing and quotation should explicitly confirm the arrangement.
Do not replace 5 core 70mm2 XLPE power cable with a 3x70+2x35 arrangement without technical approval. Different core sizes may serve different functions and must match the project design.
For 5 core 70mm2 XLPE power cable, ask for dimensions, conductor data and the specified insulation, armour and sheath. Check these details against the route, terminations and approved calculation.
Your enquiry for 5 core 70mm2 XLPE power cable should include total metres, drum lengths and the destination. Request a quotation against a named schedule revision so that size assumptions remain traceable.
| Notation | Meaning to confirm |
|---|---|
| 5x70 mm² | Five cores, each 70 mm² nominal area |
| 3x70+2x35 mm² | Three 70 mm² cores plus two 35 mm² cores |
| 4x95 mm² | Four equal 95 mm² cores if that is the specified notation |
| 3+1 core | An incomplete size description until every core area is stated |
Also identify the purpose of each core, such as phase, neutral or protective conductor, and the required identification system. The count alone does not assign those functions. Use the project’s approved earthing and circuit design rather than inferring it from a commercial model name.
Neutral and protective-conductor requirements depend on the circuit and protection design. Load imbalance, harmonics and fault duty can affect the assessment. Reducing a core to cut cost is a design change that should be reviewed by the responsible engineer, with the accepted arrangement reflected in the LV cable schedule.
The same care applies when changing from four cores to five or when proposing a separate protective conductor. Confirm the approved arrangement at both ends of the LV cable and any implications for glands, terminations and route space.
A 3x70+2x35 YJV cable supplier should confirm three 70mm2 cores and two 35mm2 cores in the proposed drawing. State the intended function of each core rather than inferring it from the model name.
Ask the 3x70+2x35 YJV cable supplier to identify the conductor material, insulation, sheath and armour requirement. A designation alone does not establish equivalence with another cable standard or construction.
Before selecting a 3x70+2x35 YJV cable supplier, check the proposed item against the engineer-approved neutral and protective-conductor arrangement. Record any alternative core sizes as a separate technical proposal.
Send the 3x70+2x35 YJV cable supplier the voltage, cable schedule revision, metres and drum plan. Request written confirmation of availability and the datasheet for the exact arrangement being priced.
Include the rated voltage, conductor material and class, insulation and sheath, armour requirement, applicable standard, colours or numbering, total metres and drum lengths. If “YJV” is used, attach the expected construction drawing. Do not assume that a model code alone establishes every material, test or installation condition.
Use one BOQ line for each distinct arrangement. A supplier offer that says only “70mm² five core” is not a complete response to a 3x70+2x35 request. Ask the supplier to restate the full arrangement and explain any variation. Keep the same notation on the purchase order, drum labels and inspection documents.
No. The nominal areas differ and the design implications must be checked.
List the area and function of every core. A four-core item and a 3+1 arrangement may use different neutral sizes; the approved drawing and calculation should resolve this before quotation or substitution.
Request the required armour and complete construction. Availability and suitability need confirmation for the particular design.
Keep the LV cable enquiry linked to the approved specification revision.
Browse the 0.6/1kV low voltage power cable range and send Honglin Cable your project enquiry. Include the approved LV cable schedule, standard, conductor, core sizes, construction, total metres and destination. State every core area and its function. Ask for a specification-specific datasheet and a written quotation confirming available construction, minimum quantity, production lead time and delivery scope.
