FAQs of XWA N2XH Cable
What is N2XH Cable?
N2XH is a European low-voltage power cable designation for fixed installations that need halogen-free and low-smoke fire behavior. It should be quoted against the project standard, not only by product name.
Where are N2XH cables typically installed?
N2XH cables are ideal for fixed installations in dry, رطوبة, or wet environments. They are widely used in indoor applications, particularly in heavily populated areas like schools, المستشفيات, المطارات, and industrial plants. They can also be installed outdoors on cable trays or brackets, provided they are shielded from direct, prolonged sunlight (unless specifically UV-resistant variants are requested).
What is the difference between N2XH and NYY cables?
The primary difference lies in the insulation and sheathing materials, which determine their fire safety performance. NYY cables use PVC (بولي فينيل كلوريد), which releases toxic, corrosive black smoke when burned. N2XH cables feature XLPE insulation and a Halogen-Free Flame Retardant (HFFR / LSZH) غمد. In the event of a fire, N2XH cables do not emit toxic gases and produce very little smoke, making them mandatory for public buildings and critical infrastructure where safe evacuation is a priority.
What does LSZH or HFFR mean?
LSZH stands for Low Smoke Zero Halogen, and HFFR stands for Halogen-Free Flame Retardant. Both terms indicate that the cable’s outer sheath is manufactured from compounds that do not contain halogens (like chlorine or fluorine). When exposed to high heat or fire, these cables restrict flame propagation and prevent the release of dangerous, vision-obscuring smoke and corrosive acids that can destroy sensitive electronic equipment.
Can N2XH cables be buried directly in the ground?
لا, standard N2XH cables are not designed for direct burial in the earth or directly into water. While they are highly durable, they lack the specific mechanical armor or water-blocking layers required for direct ground burial. If they must be routed underground, they must be installed inside protective conduits, pipes, or cable ducts.
What is the maximum operating temperature for N2XH cables?
Thanks to the robust XLPE (Cross-Linked Polyethylene) العزل, N2XH cables can safely operate at a continuous maximum conductor temperature of 90°C. In the event of a short circuit, they can withstand temperatures up to 250°C for a maximum of 5 ثواني, offering superior thermal capacity compared to standard PVC cables.
What international standards do your N2XH cables meet?
Our N2XH cables are manufactured and tested to meet rigorous international standards to ensure global compliance. This includes DIN VDE 0276-604 for power cables, اللجنة الانتخابية المستقلة 60502-1 for extruded solid dielectric cables, and critical fire behavior standards such as IEC 60332-3-24 (flame retardance) and EN 61034-2 (low smoke emission). They are also fully CPR (Construction Products Regulation) compliant for European markets.
