1. Engineering position: a three-core armoured MV cable with controlled data boundaries
N2XSEYBY is a three-core, XLPE-insulated, copper-conductor medium-voltage cable with copper wires or tapes as the metallic screen, PVC filler, PVC separation sheath, double steel tape armour and PVC outer sheath. The supplied application is fixed energy-network service in residential or industrial areas, underground routes and ducts, including routes where mechanical stresses are expected.
Electrical platform
Each phase core has a copper conductor, semiconducting conductor screen, XLPE insulation and semiconducting insulation screen. Copper wires or tapes are listed as the metallic screen.
Each phase core has a copper conductor, semiconducting conductor screen, XLPE insulation and semiconducting insulation screen. Copper wires or tapes are listed as the metallic screen.
Mechanical platform
Double steel tapes provide an armoured mechanical barrier around the PVC-separated core assembly. Armour overlap, tape dimensions, bonding and installation loads need the controlled drawing.
Double steel tapes provide an armoured mechanical barrier around the PVC-separated core assembly. Armour overlap, tape dimensions, bonding and installation loads need the controlled drawing.
Three-core platform
Three cores are grouped inside a PVC filler and separation sheath. This differs from a single-core system in phase geometry, magnetic coupling, termination arrangement and fault-current paths.
Three cores are grouped inside a PVC filler and separation sheath. This differs from a single-core system in phase geometry, magnetic coupling, termination arrangement and fault-current paths.
Evidence platform
The record supplies voltage, operating range, impact rating and flame test reference, but it does not supply conductor area, ampacity, screen section, laying factor or continuous maximum conductor temperature.
The record supplies voltage, operating range, impact rating and flame test reference, but it does not supply conductor area, ampacity, screen section, laying factor or continuous maximum conductor temperature.
Data boundary: this article does not invent a conductor cross-section, conductor flexibility class, current rating, conductor resistance, screen fault current, bending radius, service conductor temperature or fire class. Never fill a blank field from another size, supplier or cable family.
2. Designation and construction logic
| Designation / field | Engineering reading | Design consequence | Evidence status |
|---|---|---|---|
| N2X | XLPE-insulated medium-voltage cable family context. | Coordinate insulation, semiconducting screens, terminations and tests with the stated 6.35/11 kV voltage. | Source construction |
| S | Metallic screen construction; source lists copper wires or tapes. | Screen continuity, earthing and fault duty require a controlled screen section and bonding design. | Source construction |
| EYBY | Do not rely on a letter-by-letter interpretation when the source already provides the actual build: PVC filler, PVC separation sheath, double steel tapes and PVC outer sheath. | Purchase and accessory documents should reproduce the construction sequence, not only the designation. | Construction-based interpretation |
| 6/10 kV | Product family title. | The characteristic table states Uo/U as 6.35/11 kV; use the exact source notation in the project schedule. | Family title + characteristic field |
| 3 cores | Three-core cable. | Use a three-core termination and formation design; do not apply single-core cleat or screen-bond assumptions. | Official family page / PDF |
Core-by-core screen interpretation
The source lists conductor screen, XLPE, insulation screen and metallic screen before the filler. The diagram shows a screened-core concept for explanation, while the exact screen placement and dimensions remain controlled-drawing items.

3. Standard and evidence review
| Reference | Role in this article | Engineering interpretation | Boundary |
|---|---|---|---|
| IEC 60502-2 | Product standard listed by the source. | Use for the construction, dimensions and test-basis review of the applicable extruded-insulation MV cable. | Confirm the project-adopted edition and exact Feichun conformity file. |
| IEC 60332-1-2 | Flame retardant reference listed by the source. | The official IEC scope describes a vertical flame-propagation test for a single insulated wire or cable using a 1 kW pre-mixed flame. It is not a CPR class. | Source gives the standard number without an edition. |
| PVC system | PVC filler, separation sheath and outer sheath. | Review smoke, corrosive gas, halogen, fire stopping and local building requirements from the actual product documentation. | No LSZH or halogen-free claim is supplied. |
| Impact resistance | Good. | Useful as a product characteristic, but route-specific impact, compression and installation loads still require design. | No detailed impact test value is supplied. |
| CPR fire class | Not stated in the supplied N2XSEYBY record. | Do not insert Dca, Cca, Eca or any s/d/a sub-class from another Nexans or Feichun cable. | Not published. |
IEC scope check: the official IEC 60502-2 record describes extruded-insulation cables from 6 kV up to 30 kV for fixed installations such as distribution networks and industrial installations. N2XSEYBY is listed by the product source under IEC 60502-2; the exact edition and project conformity evidence still need to be controlled.
4. Complete source specification
Every user-provided field is preserved below. The article uses “Not published” or the source dash where the record does not provide a value. The official PDF adds the 250 °C short-circuit conductor temperature, while preserving the dash fields.

9. Fire and PVC performance boundary
IEC 60332-1-2
The source lists a single insulated wire or cable vertical flame-propagation reference. The official IEC publication describes the 1 kW pre-mixed flame procedure. It is not a CPR Dca / Cca / Eca class.

Confirm the current product declaration, fire barriers, penetrations, supports, cable grouping, enclosure and local construction requirements.
Mechanical and fire trade-off
Steel tape armour and PVC provide a different design profile from LSZH aluminium-armoured cables. Selection should be made against the actual mechanical, fire and environmental priority.

Procurement rule: do not market this source record as LSZH, halogen-free, Dca, Cca, Eca or fire-resistant unless the exact Feichun construction has a matching current declaration and test report.
10. Fixed-route application architecture
Energy-network feeder

11. Handling and termination
- Confirm the exact product code, current source revision, cable length, conductor area, outside diameter, mass and end seals before unloading.
- Do not use a calculated bend radius: the source states
- (xD). Obtain the controlled installation factor and accessory method statement before laying. - Align the drum and pay off in the marked direction. Prevent reverse winding, flange impact, uncontrolled twist and local PVC sheath damage.
- Use controlled rollers and pulling equipment. Verify pulling load, sidewall pressure, support spacing, trench entry, duct entry and armour loading.
- Prepare the three-core termination with the correct phase identification, screen continuity, PVC separation, steel tape armour treatment and gland / accessory dimensions.
- Bond the metallic screen and armour according to the approved earthing design. Record continuity, torque, phase identity and test results.
- Before energisation, complete conductor resistance, screen continuity, insulation / sheath tests, MV withstand or partial-discharge tests where specified, phase identification, accessory inspection and as-built records.
Installation release: no minimum radius, conductor service temperature or conductor size should appear in a Feichun installation method statement until the current controlled data sheet closes the dash fields.
12. Selection comparison for engineers
| Requirement | N2XSEYBY reference | What must be verified | Engineering decision |
|---|---|---|---|
| Three-phase fixed MV feeder | Three-core copper / XLPE construction; 6.35/11 kV Uo/U. | Conductor area, current rating, voltage drop, fault duty, termination and phase identification. | Potentially suitable after data release. |
| Mechanically exposed fixed route | Good impact resistance; double steel tape armour. | Impact level, compression, armour overlap, pulling load, support and trench / duct entry. | Candidate subject to mechanical design. |
| Underground / duct route | Application listed by the source. | Water exposure, drainage, soil thermal resistance, duct fill, fire stopping and joint access. | Confirm route construction. |
| Fire-sensitive building or tunnel | IEC 60332-1-2 listed; PVC sheath system. | Current fire declaration, smoke / corrosive gas evidence, grouping and local requirements. | Do not assume LSZH or CPR class. |
| Continuous current sizing | Conductor cross-section and service maximum temperature are “-”. | All thermal and voltage-drop inputs are incomplete. | Stop until data is published. |
| Reeling / festoon / drag chain | No bending factor; fixed-route application wording. | Cycles, torsion, speed, acceleration, rollers and dynamic bend radius. | Select a dedicated dynamic cable family. |
13. Failure mode and effects analysis
Wrong conductor size: the cable is ordered without resolving the “- mm²” field, making ampacity, voltage drop and accessory selection impossible.
Radius assumption: a 15×D or 12×D value from another cable is copied even though this record states “- (xD)”.
Continuous temperature substitution: 90 °C from another XLPE family is treated as the N2XSEYBY service limit.
Screen fault path: copper screen and steel tape armour are assumed to carry a known earth-fault current without a section or bonding study.
Fire-class substitution: IEC 60332-1-2 is treated as proof of Dca, Cca, Eca, LSZH or halogen-free performance.
Armour damage: incorrect rollers, pulling or trench entries deform the double steel tapes or PVC sheath.
Revision confusion: the supplied 8/4/26 source record and the live PDF’s 7/8/26 metadata are merged without verifying which controlled document governs.
Dynamic misuse: the fixed-installation cable is placed in reeling, festoon or energy-chain service without a dynamic qualification.
14. Feichun Cable certification and project assurance
Engineered for maximum safety in demanding environments, Feichun Cable cable systems comply with global standards including ATEX, IECEx, VDE, CE, UKCA, EAC, and the Russian Fire Safety Certificate. They are the trusted choice for heavy-duty mining equipment, ship-to-shore cranes, RTG/RMG cranes, and conveyor systems where high reliability is non-negotiable.
For a Feichun N2XSEYBY release
Confirm conductor area, conductor flexibility, outer diameter, mass, DCR, current rating, voltage-drop data, screen section, screen / armour fault duty, bending factor, service conductor temperature, fire classification and accessory compatibility.
Confirm conductor area, conductor flexibility, outer diameter, mass, DCR, current rating, voltage-drop data, screen section, screen / armour fault duty, bending factor, service conductor temperature, fire classification and accessory compatibility.
Certification is configuration-specific
Certification capability does not make every N2XSEYBY size automatically IEC 60502-2, IECEx, ATEX, EAC or fire-certified. The exact three-core construction and documentation must match.

Feichun engineering value
Feichun can develop the three-core XLPE / copper-screen / PVC / double-steel-tape architecture around the actual conductor size, route mechanics, protection system and market documentation instead of copying an incomplete reference label.
