1. Engineering position: a three-core armoured MV cable with controlled data boundaries
N2XSEHRH is a three-core, XLPE-insulated, copper-conductor medium-voltage cable with copper tape as the metallic screen, LSZH filler, LSZH separation sheath, single-layer galvanized steel wire armour and LSZH 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 tape are listed as the metallic screen.
Each phase core has a copper conductor, semiconducting conductor screen, XLPE insulation and semiconducting insulation screen. Copper tape are listed as the metallic screen.
Mechanical platform
Single-layer galvanized steel wires provide an armoured mechanical barrier around the LSZH-separated core assembly. Armour overlap, tape dimensions, bonding and installation loads need the controlled drawing.
Single-layer galvanized steel wires provide an armoured mechanical barrier around the LSZH-separated core assembly. Armour overlap, tape dimensions, bonding and installation loads need the controlled drawing.
Three-core platform
Three cores are grouped inside a LSZH 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, the 70 / 95 / 120 / 150 / 185 / 240 / 300 / 400 mm² matrix and current ratings; screen section and route-specific ampacity still require confirmation.

Data boundary: this article does not invent a conductor size outside the supplied 70 / 95 / 120 / 150 / 185 / 240 / 300 / 400 mm² rows, 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 tape. | Screen continuity, earthing and fault duty require a controlled screen section and bonding design. | Source construction |
| RH / construction record | Do not rely on a letter-by-letter interpretation when the source already provides the actual build: LSZH filler, LSZH separation sheath, single galvanized steel wires and LSZH outer sheath. | Purchase and accessory documents should reproduce the construction sequence, not only the designation. | Construction-based interpretation |
| 6.35/11 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 60332-3 Cat. C | Flame retardant reference listed by the source. | The source uses a bunched-cable vertical flame-spread test reference, Category C. It is not itself a CPR class. | Source gives the standard number without an edition. |
| LSZH system | LSZH filler, separation sheath and outer sheath. | Review smoke, corrosive gas, halogen, fire stopping and local building requirements from the actual product documentation. | LSZH and halogen-free construction are specified; confirm the current compound and test reports. |
| 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 | Cca is stated in the supplied family title. | Use Cca as the stated class; do not add unprovided smoke, droplet or acidity qualifiers. | 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. N2XSEHRH is listed by the product source under IEC 60502-2; the exact edition and project conformity evidence still need to be controlled.

5. Published-data limitations and what cannot yet be calculated
| Required design input | Source state | Why it matters | Required Feichun release action |
|---|---|---|---|
| Conductor cross-section | 70 / 95 / 120 / 150 / 185 / 240 / 300 / 400 mm² | The matrix supplies area, resistance, mass and diameter; formation-specific accessory and installation verification remain necessary. | Publish a size-specific data sheet and product code. |
| Continuous maximum conductor temperature | 90 °C | Operating range -20 … 90 °C is not a continuous conductor-temperature declaration. | Confirm continuous service limit with XLPE, screen, sheath and accessories. |
| Bending factor when laying | 12 (xD) | A size-specific laying-radius screening value can be calculated; pulling and entry geometry cannot be released safely. | Publish installation factor and accessory-specific limits. |
| Current ratings | 253–683 A in air; 220–541 A buried across the matrix | The supplied flat ratings still require recalculation for the actual formation, ambient, soil and grouping. | Publish or calculate ratings with the stated installation basis. |
| Screen / armour fault duty | Not supplied | Earth-fault path, screen bonding, galvanized steel wire behaviour and protection coordination remain unresolved. | Release screen section, armour details and I²t capability. |
| Fire classification | Cca | The product-specific DoP declares Cca; do not infer additional s/d/a qualifiers. | Provide product-specific declaration if required by the project. |
Engineering stop condition: the cable can be described and structurally reviewed from the source, but it cannot be fully sized, thermally rated or radius-released until the missing fields are closed for the exact Feichun construction.

8. Layer-by-layer cross-section
The source sequence is: copper conductor; semiconducting conductor screen; XLPE insulation; semiconducting insulation screen; copper tape metallic screen; LSZH filler; LSZH separation sheath; single galvanized steel wires; LSZH outer sheath. The cross-section is intentionally labelled as a conceptual screened-core arrangement because the source does not publish exact screen placement, core dimensions or armour geometry.
Three insulated cores
Each phase is shown with the listed conductor screen, XLPE insulation and insulation screen. The source does not publish the conductor area.

10. Thermal, voltage-drop and short-circuit design
Thermal rating cannot be copied
The matrix publishes 70 / 95 / 120 / 150 / 185 / 240 / 300 / 400 mm², current ratings and 90 °C service temperature; recalculate for the actual formation rather than borrowing a rating from another cable.

Voltage drop needs conductor data
A 6.35/11 kV label does not provide conductor resistance, inductance or load capacity. The project needs conductor area, route length, power factor, load profile and installation formation.

Mechanical and fire trade-off
Galvanized steel wire armour and LSZH provide a different design profile from aluminium-armoured constructions. Selection should be made against the actual mechanical, fire and environmental priority.

Procurement rule: do not upgrade the stated Cca class to Cca, B2ca or unprovided s/d/a qualifiers; the exact Feichun construction still requires a matching current declaration and test report.
12. Fixed-route application architecture
Energy-network feeder
The source identifies low dielectric losses and networks with sudden load changes. Final selection still needs conductor area, load profile and protection study.

This record has no bending factor and is not established as a reeling, festoon, drag-chain or continuous-torsion cable.
13. 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
12 (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 LSZH 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, LSZH separation, steel wire 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.
14. Selection comparison for engineers
| Requirement | N2XSEHRH 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; single-layer galvanized steel wire 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 60332-3 Cat. C listed; LSZH sheath system. | Current fire declaration, smoke / corrosive gas evidence, grouping and local requirements. | Use the Cca declaration and exact project fire requirements. |
| Continuous current sizing | Conductor cross-section, 90 °C service limit and 12 (xD) laying factor are published. | Use the supplied matrix, then recalculate for the actual formation and route. | Calculate for the actual route. |
| Reeling / festoon / drag chain | 12 (xD) laying factor; fixed-route application wording. | Cycles, torsion, speed, acceleration, rollers and dynamic bend radius. | Select a dedicated dynamic cable family. |
15. Failure mode and effects analysis
Wrong conductor size: the cable is ordered without resolving the “70 / 95 / 120 / 150 / 185 / 240 / 300 / 400 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 “12 (xD)”.
Continuous temperature substitution: 90 °C is used without checking formation, ambient, grouping and accessory limits.
Screen fault path: copper screen and steel wire armour are assumed to carry a known earth-fault current without a section or bonding study.
Fire-class substitution: IEC 60332-3 Cat. C is treated as a substitute for the product Cca declaration or the route fire strategy.
Armour damage: incorrect rollers, pulling or trench entries deform the single galvanized steel wires or LSZH sheath.
Revision confusion: the family-level 8/4/26 record and the older 3×95 mm² product PDF generated 9/14/25 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.
16. 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 N2XSEHRH 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.

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