FAQs of XWA N2XOH Cable
What does the N2XOH cable designation stand for?
The N2XOH naming convention follows standard European (DIN VDE) and South American (NTP) designations for power cables:
- norte: Indicates a standard copper conductor.
- 2incógnita: Denotes the XLPE (Cross-Linked Polyethylene) aislamiento, which allows for a high continuous operating temperature of 90°C.
- OH: Signifies a Halogen-Free Flame Retardant (HFFR / LSZH) funda exterior.
Where is N2XOH cable primarily used?
Because of its halogen-free and low-smoke properties, N2XOH is the standard choice for environments where fire safety is the absolute top priority. It is heavily specified in public infrastructure, particularly across European and Latin American markets (such as Peru and Chile). Typical applications include hospitals, centros comerciales, aeropuertos, underground transit systems, and enclosed industrial control rooms. En caso de incendio, the sheath will not emit toxic, corrosive gases or thick black smoke, ensuring safe evacuation and protecting sensitive electronic equipment.
What is the difference between N2XY and N2XOH?
Both cables share the same copper conductor and XLPE insulation, meaning their electrical capacity and temperature ratings are identical. The primary difference is the material of the outer jacket:
- N2XY uses a standard PVC sheath. It is cost-effective but will release toxic halogen gases and heavy smoke when burned.
- N2XOH uses a Halogen-Free (OH) vaina, making it the safer, premium alternative required by modern building codes for densely populated enclosed spaces.
What do specifications like 1x, 2incógnita, and 3x mean for N2XOH?
The notation “1incógnita”, “2incógnita”, o “3incógnita” refers to the number of individual cores inside the cable jacket, followed by the cross-sectional area of the copper in square millimeters (mm²). While tiny 1mm² sizes (p.ej., 1×1, 2×1) exist for light signaling and control wiring, standard 0.6/1kV power distribution typically starts at 1.5mm². The most utilized configurations include:
- Un solo núcleo (1incógnita): Such as 1×1.5 mm² up to 1×300 mm². These are heavily used for main power feeds, heavy machinery, and complex switchgear routing where individual phases are pulled separately.
- Two-Core (2incógnita): Such as 2×1.5 mm² or 2×2.5 mm². Commonly used for standard single-phase power supply without a dedicated grounding core.
- Three-Core (3incógnita): Such as 3×1.5 mm², 3×2.5 mm², or 3×120 mm². These are the industry standards for three-phase industrial power systems, feeding large motors, distribution panels, and heavy HVAC units.
Can N2XOH cable be installed directly underground?
While the XLPE insulation provides excellent moisture resistance, the halogen-free outer sheath is generally not as mechanically rugged as standard PVC or steel-armored cables. Por lo tanto, if N2XOH is buried underground, it must be installed inside protective conduits or buried cable ducts to prevent mechanical damage from rocks, soil pressure, or rodents.
Qué hace que el cable N2XOH cumpla con el estándar de la UE?
El cable N2XOH se incluye en la norma unificada de baja emisión de humos y cero halógenos de la UE (LSZH) cable category and fully complies with the EN50525-2-11 European standard for low-voltage power cables. Además, it carries mandatory CE marking for EU markets and EAC certification for Eurasian Union regions — ensuring you avoid non-compliance delays during project inspections or customs clearance.
Its rated voltage of 0.6/1kV matches the requirements of most low-voltage power distribution systems. Además, Esta clasificación de voltaje significa que el cable funciona perfectamente para tareas generales de suministro de energía en entornos comerciales e industriales sin requerir una reducción de voltaje adicional..
Why N2XOH cable's sheath use LSZH flame-retardant material?
The outer sheath uses low-smoke zero-halogen (LSZH) compuesto retardante de llama, típicamente negro para resistencia a los rayos UV en exteriores. En caso de incendio, Esta funda libera muy poco humo y no produce gases halógenos tóxicos.. Esta es una ventaja de seguridad crítica en espacios de alta ocupación como oficinas., centros comerciales, y hospitales, donde la inhalación de humo y los daños causados por gases corrosivos a los dispositivos electrónicos son las principales preocupaciones durante los incidentes de incendio.
What are the installation limitations to note of N2XOH cables?
El cable N2XOH no es adecuado para todos los entornos de instalación., y comprender sus limitaciones evita costosos errores de especificación.
Primero, the cable is not rated for direct burial underground. Sin protección de armadura, no puede soportar la presión de aplastamiento, exposición a la humedad, y penetración de raíces que requieren las aplicaciones de entierro directo. Para recorridos subterráneos, a steel wire armoured (SWA) o alambre de aluminio blindado (AWA) cable a IEC 60502-1 es la especificación apropiada.
Segundo, N2XOH is not suitable for continuous immersion in water or permanently wet underground environments.
Tercero, for outdoor exposed installation, El cable requiere protección mecánica adicional contra la luz solar directa, la degradación por rayos UV y el impacto físico.. Aunque la funda negra estándar proporciona cierta resistencia a los rayos UV, la exposición prolongada al aire libre sin protección no está dentro de la categoría de instalación nominal del cable.
