N2XS(F)2und Kabel | Copper XLPE Water-Blocked MV Cable

Q: Are N2XS(F)2Y and N2XS2Y interchangeable?

Not automatically. The (F) construction includes longitudinal water blocking; an ordinary PE-sheathed cable should not be assumed to provide the same water-penetration performance.

N2XS(F)2und Kabel is a screened single-core copper power cable with XLPE insulation, ein Schirm aus Kupferdraht, longitudinal water-blocking components and a PE outer sheath. It is intended for fixed medium-voltage distribution rather than flexible trailing service.

The copper conductor carries load current; the surrounding screen performs a separate electrical duty. Industrial feeders, substation circuits and underground networks use this construction where the voltage, bonding arrangement and route conditions match the cable-system design.

Copper single-core N2XS(F)2Y, 12/20 kV, copper wire screen and PE sheath. The listed dimensions, mass and current ratings apply to this reference construction and the installation conditions below.

Ampacity basis: one circuit in touching trefoil, screens solidly bonded; air 30°C without direct sun; ground 20°C at 0.7 m depth. Source assumptions include 1.0 K·m/W wet soil and 2.5 K·m/W dry soil, with no additional heat sources. Reference conductor limit: 90°C.

Kupferleiter, metallic screen and the (F) Bezeichnung

In a reference 1×240/25 Konstruktion, 240 mm² belongs to the phase conductor and 25 mm² to the metallic screen. Screen fault-current duty, protection clearing time and accessory connections are separate from continuous conductor ampacity.

Der (F) construction uses water-blocking components to limit moisture propagation along the cable. N2XS(FL)2Y adds a laminated metallic barrier beneath the PE sheath for radial moisture protection. A PE sheath alone does not provide the same barrier construction.

Comparison of ordinary PE sheath, longitudinal water blocking and a longitudinal plus radial barrier construction — Der (F) Und (FL) variants are different constructions, not interchangeable spelling choices.

Applications and Installation Conditions

Fixed industrial power intake, substation feeders and underground distribution can use this screened construction. Unarmoured cable still needs route-specific mechanical protection. Indoor fire requirements, water exposure and accessory interfaces must match the stated design; the model name alone does not establish submarine suitability.

The test schedule distinguishes conductor resistance, insulation tests and sheath checks from the evidence for the (F) Wasserbarriere. Screen connections and accessory interfaces also belong to the cable-system specification. The IEC publication scope explains the fixed-installation framework; certification requires separate evidence.

N2XS(F)2Häufig gestellte Fragen zu Y-Kabeln

Are N2XS(F)2Y and N2XS2Y interchangeable?

Nicht automatisch. Der (F) construction includes longitudinal water blocking; an ordinary PE-sheathed cable should not be assumed to provide the same water-penetration performance.

What does 1×240/25 identify?

One 240 mm² phase conductor and a separately specified 25 mm² metallic screen in the reference construction. The screen is not another power core.

Can the displayed ampacity be used for ducts?

Not directly. The table uses the stated trefoil, bonding and thermal conditions. Kanäle, surrounding materials and grouped circuits require the applicable current-rating calculation.
