What Makes N2XOH Cable EU-Standard Compliant?
N2XOH cable falls under the EU’s unified low-smoke zero-halogen (LSZH) cable category and fully complies with the EN50525-2-11 European standard for low-voltage power cables. بالإضافة إلى, 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 0.6/1كيلو فولت matches the requirements of most low-voltage power distribution systems. In addition, this voltage rating means the cable works seamlessly for general power supply tasks in commercial and industrial settings without requiring additional voltage derating.
Core Structural Features of N2XOH Cable
موصل: فصل 2/5 نحاس
The conductor uses multi-strand bare copper meeting اللجنة الانتخابية المستقلة 60228 فصل 2/5 المعايير.
Insulation Layer: 90°C XLPE
The insulation uses البولي إيثيلين المتقاطع (XLPE) with a continuous operating temperature rating of 90درجة مئوية. Compared to standard PVC insulation, which is typically rated at 70°C, XLPE provides significantly more stable performance during prolonged high-load operation. نتيجة ل, the risk of insulation softening, short circuits, or electrical faults under sustained load is considerably reduced — an important advantage in commercial buildings with heavy and continuous power demand.
الغلاف الخارجي: LSZH Flame-Retardant Material
The outer sheath uses low-smoke zero-halogen (LSZH) flame-retardant compound, typically black for outdoor UV resistance. In the event of a fire, this sheath releases very little smoke and produces no toxic halogen gases. This is a critical safety advantage in high-occupancy spaces such as offices, shopping centres, and hospitals, where smoke inhalation and corrosive gas damage to electronics are primary concerns during fire incidents.
تحديد الهوية الأساسية
By default, N2XOH cable uses black core wires with white numerical coding for straightforward installation and fault tracing. بالإضافة إلى ذلك, custom versions with dedicated earth marking wires are available to match specific project wiring standards or local regulatory requirements.
Ideal Application Scenarios for N2XOH Cable
N2XOH cable is designed for التثبيت الثابت and performs reliably across three core environments: indoor spaces, outdoor covered areas, and embedded in concrete.
Commercial and High-Occupancy Buildings
N2XOH is the first choice for power wiring in office buildings, مراكز التسوق, hotels, and hospitals. In these environments, dense foot traffic and high-value equipment make LSZH fire performance a regulatory and practical requirement. The cable’s EN50525-2-11 compliance satisfies EU building regulations for cables installed in escape routes and occupied spaces. Moreover, the 90°C XLPE insulation supports the sustained load cycles typical in commercial buildings with round-the-clock operation.
Industrial Facilities
In factories, manufacturing plants, and industrial warehouses, N2XOH is commonly used for internal power distribution runs — from main distribution boards to sub-distribution panels, المحركات, and fixed equipment. Its LSZH sheath meets the fire safety requirements increasingly required by industrial insurers and local building authorities.
Embedded and Concrete-Cast Installation
N2XOH is also approved for direct embedding in concrete — for example, in underfloor or wall-embedded power runs in commercial construction. لكن, this application requires correct conduit or protective duct installation around the cable where mechanical damage during construction is possible.
Installation Limitations to Note
N2XOH cable is not suitable for all installation environments, and understanding its limitations prevents costly specification errors.
أولاً, the cable is not rated for direct burial underground. Without armour protection, it cannot withstand the crush pressure, moisture exposure, and root penetration that direct-burial applications require. For underground runs, أ steel wire armoured (سوا) or aluminium wire armoured (أوا) cable to IEC 60502-1 is the appropriate specification.
ثانية, N2XOH is not suitable for continuous immersion in water or permanently wet underground environments.
Third, ل outdoor exposed installation, the cable requires additional mechanical protection against direct sunlight UV degradation and physical impact. Although the standard black sheath provides some UV resistance, prolonged unprotected outdoor exposure is not within the cable’s rated installation category.
Common N2XOH Cable Sizes and Technical Specifications
N2XOH cable is available in both single-core and multi-core configurations. Popular stock sizes include 1×16mm², 1×185mm², 1×240mm², and 4×16mm². For larger high-load applications, 1×300mm² variants are also available.
The following specifications apply to the most commonly sourced large single-core sizes.
1×185mm² N2XOH has a nominal outer diameter of 25mm and an approximate weight of 1,910kg per kilometre. This size is widely used for main feeder runs in medium-scale commercial buildings and industrial sub-distribution.
1×240mm² N2XOH has a nominal outer diameter of 28mm and an approximate weight of 2,370kg per kilometre. It is one of the most commonly specified sizes for main LV incoming feeders in large commercial buildings and distribution substations.
1×300mm² N2XOH has a nominal outer diameter of 30mm and an approximate weight of 2,970kg per kilometre. This is the largest standard single-core size and is typically used for high-current main feeder applications where copper conductor size is preferred over aluminium for space-constrained cable routes.
These specifications allow you to calculate conduit size requirements, cable tray load limits, and transportation weight constraints accurately during project planning.

الأسئلة الشائعة
1. What European standard does N2XOH cable comply with? N2XOH cable fully complies with EN50525-2-11, the European standard for low-voltage power cables with LSZH insulation and sheath. In addition, it carries CE marking for EU markets and EAC certification for Eurasian Union regions — both of which are required for project compliance in these markets.
2. Is N2XOH cable suitable for direct burial underground? لا. N2XOH cable is not rated for direct burial or continuous immersion in water. It lacks the mechanical armour protection required to withstand soil pressure, moisture ingress, and root penetration in underground environments. For direct burial applications, a steel wire armoured cable to IEC 60502-1 is the correct specification instead.
3. What is the temperature rating of N2XOH cable’s XLPE insulation? The XLPE insulation of N2XOH cable has a continuous operating temperature rating of 90°C. This is significantly higher than standard PVC insulation, which is typically rated at 70°C. نتيجة ل, N2XOH maintains stable electrical performance during sustained high-load operation — an important advantage in commercial buildings with round-the-clock power demand.
4. Why is N2XOH cable recommended for shopping malls and office buildings? N2XOH uses an LSZH outer sheath that releases minimal smoke and no toxic halogen gases during a fire. This directly reduces the risk of smoke inhalation injury to building occupants and corrosive gas damage to high-value electronic equipment. بالإضافة إلى, its EN50525-2-11 compliance satisfies EU building regulations for cables installed in escape routes and occupied spaces.
5. What is the weight of 1×240mm² N2XOH cable per kilometre? A 1×240mm² N2XOH cable has an approximate weight of 2,370kg per kilometre and a nominal outer diameter of 28mm. These values are used to calculate cable tray load ratings, conduit fill requirements, and transportation logistics during project planning.
6. What conductor class does N2XOH cable use, and why does it matter? N2XOH uses a Class 2/5 copper conductor to IEC 60228.
