N2XS2Y-Kabel
N2XS2Y-Kabel is a single-core medium-voltage power cable with a stranded copper conductor, XLPE-Isolierung, copper wire screen and polyethylene outer sheath.
The designation is used for fixed medium-voltage distribution where a PE-sheathed cable is preferred for underground, water-exposed, im Freien, duct and demanding utility routes. Common project voltage classes include 6/10 kV, 8.7/15 kV, 12/20 kV and 18/30 kV under IEC and VDE-oriented specifications.
XWA supplies N2XS2Y as a project cable configuration where conductor size, copper screen section, voltage class, PE sheath requirement, test documents and export packing are matched to the cable schedule and destination market.

N2XS2Y Cable Technical Data
Recommended Reference Data: N2XS2Y is normally a single-core screened medium-voltage cable. The size format below is conductor cross-section / copper screen cross-section in mm2.
Ampacity values are reference values for one single-core circuit in air at 30°C with load factor 1.0 and three-cable bunching, or in ground at 20°C with load factor 0.7 and three-cable bunching. Final project current rating depends on soil thermal resistivity, burial depth, Abstand, grouping, sheath bonding, route temperature and local calculation method. Final XWA manufacturing dimensions and test values follow the approved quotation datasheet.

N2XS2Y Cable Construction
N2XS2Y is built around a stranded copper conductor with an extruded conductor screen, XLPE insulation and an insulation screen applied as part of the medium-voltage insulation system. A copper wire screen and counter helix provide the metallic screen path, followed by a polyethylene outer sheath.
The single-core construction is important. Current rating, screen bonding, induced sheath voltage, bending radius and termination design are evaluated differently from three-core MV cable. Where a tender requires a three-core screened cable, N2XSEY or another three-core designation may be the better match.
The copper screen section, commonly shown as the second number in a size such as 1 X 240/25 mm2, is selected according to earth-fault current and protection design. It is not decorative and must match the fault-current requirement of the system.
Applications for N2XS2Y Medium Voltage Cable
N2XS2Y cable is used in medium-voltage distribution networks where a screened single-core cable with PE sheath is accepted by the project specification. Common routes include transformer stations, switching stations, power plants, industrielle Feeder, renewable-energy collection networks and utility distribution circuits.
The cable can be installed indoors, outdoors, in ducts, in water and in ground routes when the installation design accounts for mechanical protection, pulling tension, Biegeradius, route temperature and current rating. The PE sheath supports stronger mechanical and moisture-resistance positioning than a conventional PVC sheath.
The PE sheath is not normally treated as a flame-retardant sheath under flame-test definitions used for PVC-sheathed cable. For tunnels, public buildings or routes requiring flame-retardant or low-smoke halogen-free performance, another MV cable design may be required.
N2XS2Y vs N2XSY, NA2XS2Y and N2XS(F)2Y
N2XS2Y and N2XSY share copper conductor, XLPE insulation and screened single-core MV cable logic, but the outer sheath differs. N2XSY uses PVC sheath; N2XS2Y uses PE sheath for routes where mechanical durability, water exposure or underground service is a stronger requirement.
NA2XS2Y is the aluminium-conductor companion to N2XS2Y. It can reduce conductor cost and weight, but conductor size, Widerstand, termination design and short-circuit performance are different from copper N2XS2Y.
N2XS(F)2Y adds a longitudinal water-blocking construction detail. It should not be treated as identical to standard N2XS2Y unless the project specification requires the `(F)` water-blocking layer and XWA confirms that construction.
| Modell | Main distinction | Typical page role |
|---|---|---|
| N2XSY | Copper conductor with PVC sheath | PVC-sheath comparison |
| N2XS2Y | Copper conductor with PE sheath | This page |
| NA2XS2Y | Aluminium conductor with PE sheath | Next companion page |
| N2XS(F)2Y | Copper conductor with PE sheath and longitudinal water blocking | Separate water-blocked variant |
Testen, Documents and Export Packing
N2XS2Y production documentation can include the approved datasheet, conductor resistance checks, voltage test records, partial-discharge test records, dimensional inspection, drum schedule, packing list and product photos. Type tests, flame-test evidence or third-party inspection are added only when required by the project and available for the exact construction.
Export packing is normally planned by cable weight, Trommellänge, maximum drum diameter, route handling and container loading. Medium-voltage single-core cable can become heavy at large cross-sections, so drum length is part of the technical and logistics review, not only a shipping preference.
For quotation, XWA needs the model designation, voltage class, Leitergröße, copper screen section, installation route, Standard, Menge, preferred drum length, destination country and required documents. The information is used to confirm the cable configuration and issue a project-specific offer.
N2XS2Y Cable FAQs
What is N2XS2Y Cable?
N2XS2Y Cable is a screened single-core medium-voltage power cable with a copper conductor, XLPE-Isolierung, copper wire screen and polyethylene outer sheath. It is used for fixed MV distribution routes in utility, substation, industrial and generation systems.
What voltage classes are common for N2XS2Y Cable?
Common N2XS2Y voltage classes include 6/10 kV, 8.7/15 kV, 12/20 kV and 18/30 kV. The project cable schedule defines the required Uo/U voltage class and test-voltage requirement.
What is the construction of N2XS2Y Cable?
The typical construction is Class 2 stranded copper conductor, conductor screen, XLPE-Isolierung, insulation screen, copper wire metallic screen with counter helix and PE outer sheath. The screen section and sheath material are specified by the project.
Is N2XS2Y a single-core or three-core cable?
N2XS2Y is normally a single-core medium-voltage cable. Three-core MV requirements should be checked separately because the cable design, screen arrangement, bending radius and accessories are different.
What does 1 X 240/25 mean in N2XS2Y Cable?
In a size such as 1 X 240/25 mm2, 240 mm2 is the copper conductor cross-section and 25 mm2 is the copper screen cross-section. The screen value must match the earth-fault duty and protection design.
Where is N2XS2Y Cable used?
N2XS2Y is used in transformer stations, switching stations, power plants, industrial distribution networks, renewable-energy collection circuits, cable ducts and underground utility routes where PE-sheathed MV cable is accepted.
What is the difference between N2XS2Y and N2XSY?
N2XS2Y uses a PE outer sheath. N2XSY uses a PVC outer sheath. PE sheath can be preferred for underground, water-exposed or mechanically demanding routes, while PVC sheath remains common where flame behaviour, handling or project convention points to PVC.
What is the difference between N2XS2Y and N2XS(F)2Y?
N2XS(F)2Y adds longitudinal water-blocking layers around the metallic screen area. Standard N2XS2Y should not be described as an `(F)` water-blocked cable unless that construction is specified and confirmed.
Can N2XS2Y Cable be installed underground?
N2XS2Y can be installed in ground or water-exposed routes when the cable design, route protection and local rules permit it. Current rating and service life depend on burial depth, soil thermal resistivity, Abstand, grouping, moisture and mechanical protection.
What information does XWA need to quote N2XS2Y Cable?
For a project quotation, XWA needs the N2XS2Y voltage class, Leitergröße, copper screen section, Standard, installation route, Menge, Trommellänge, destination country and required inspection or test documents.
