NHXH FE180 E30 Cable

What is NHXH FE180 E30 Cable?

The NHXH FE180-E30 Cable is a German-standard, unarmoured, low-voltage (0.6/1kV) fire-survival power and control cable engineered in accordance with DIN VDE 0266 and DIN VDE 0276-604. It is developed for fixed installations across public buildings, transit centers, and commercial complexes requiring continuous electrical function during initial fire emergency stages.

The FE180-E30 rating signifies two critical safety performance levels: FE 180 verifies insulation integrity under continuous burner flame exposure for 180 minutes according to DIN VDE 0472-814 and IEC 60331, while E 30 validates functional circuit integrity for at least 30 minutes when installed in certified support assemblies. Formulated from low-smoke zero-halogen (LSZH) thermoplastic materials, the cable does not emit corrosive acid gases and produces minimal optical smoke during combustion, ensuring visibility along evacuation routes and preventing acid to electronics.

NHXH FE180-E30 Cable Construction

• Conductor: High-purity plain annealed copper; RE Class 1 circular solid copper or RM Class 2 circular/compacted stranded copper per EN 60228.
• Insulation: Cross-linked Low Smoke Zero Halogen (LSZH) flame-resistant compound.
• Inner Sheath / Bedding: Extruded Low Smoke Zero Halogen (LSZH) compound enclosing the laid-up cores.
• Screen / Armour: Unscreened and unarmoured lightweight design for straightforward installation in conduits and cable trays.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) flame-retardant compound.
• Core Identification: 3 cores: Brown, Blue, Green/Yellow; 4 cores: Brown, Black, Grey, Blue; 5 cores: Brown, Black, Grey, Blue, Green/Yellow; 7 cores and above: Black with continuous White numerical numbering.
• Sheath Colour: Safety Orange.

Applications

NHXH FE180-E30 safety cables are engineered for fixed wiring across systems where 30-minute operational circuit survival is legally required:

• Emergency Lighting & Signage: Power lines for illuminated exit signage, central battery emergency lighting systems, and alarm indicators.
• Smoke Dampers & Pressurization Fans: Connection feeds to automated fire doors, smoke damper actuators, and positive-pressure ventilation fans.
• Fire Alarm & Warning Infrastructure: Power links for fire warning speakers, detection control panels, and automated emergency notification circuits.
• High-Occupancy Public Buildings: Hospitals, airports, subway platforms, retail hubs, and academic institutions for indoor and outdoor routing (not permitted for direct burial in soil or immersion in water).

Frequently Asked Questions

Q: What is the main distinction between NHXH and NHXCH cables?
A: NHXH is an unarmoured and unscreened cable designed for general fire-resistant power transmission, whereas NHXCH includes an additional concentric copper wire and tape screen that provides electromagnetic shielding (Cable) and serves as an earth return conductor.

Q: Can NHXH FE180-E30 cable be installed outdoors or buried underground?
A: The cable can be used in indoor and outdoor exposed installations, but it is explicitly not permitted for direct burial in soil or immersion in water.

Q: What does the E30 circuit integrity rating ensure during a fire?
A: The E30 classification certifies that the complete installed system—including cable, support brackets, and fixings—will maintain electrical continuity for at least 30 minutes under standard fire curve conditions, allowing emergency lighting and alarms to function during evacuations.

Q: What payment terms does Huadong Cable accept for international orders?
A: We accept standard international commercial payment terms, primarily Telegraphic Transfer (T/T, 30% advance deposit and 70% against shipping documents) and 100% Irrevocable Letter of Credit (L/C) at sight.
