NHXCH FE180 E90 Cable

What is NHXCH FE180 E90 Cable?

The NHXCH FE180-E90 Cable is a German-standard, halogen-free, low-voltage (0.6/1kV) fire-survival power and control cable engineered in compliance with DIN VDE 0266 and DIN VDE 0276-604. It is specifically designed for fixed indoor installations across critical public facilities, commercial complexes, and industrial networks where stringent fire safety regulations require the preservation of equipment operation and human safety during thermal events.

The designation FE180-E90 signifies superior fire protection performance: FE 180 denotes insulation integrity under direct flame exposure for up to 180 minutes according to DIN VDE 0472-814 and IEC 60331, while E 90 confirms functional system circuit integrity for a minimum of 90 minutes in full cable-support assemblies. Featuring cross-linked halogen-free insulation, an integrated concentric copper screen, and an orange LSZH outer sheath tested to IEC/EN 60332-3-24, the cable emits no corrosive acid fumes and produces minimal optical smoke, ensuring clear escape routes and protecting digital equipment from acidic degradation.

NHXCH FE180-E90 Cable Construction

• Conductor: High-conductivity plain annealed copper; RE Class 1 circular solid copper or RM Class 2 circular/shaped stranded copper conforming to 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.
• Concentric Conductor / Screen: Layer of plain copper wires bound with an open counter-helical copper tape, acting as a low-impedance neutral/protective earth conductor and EMC shield.
• Outer Sheath: Thermoplastic Low Smoke Zero Halogen (LSZH) flame-retardant compound.
• Core Identification: 2 cores: Brown, Blue; 3 cores: Brown, Black, Grey; 4 cores: Brown, Black, Grey, Blue; 5 cores: Brown, Black, Grey, Blue, Black; 7 cores and above: Black with continuous White numerical numbering.
• Sheath Colour: Safety Orange.

Applications

NHXCH FE180-E90 safety cables are engineered for indoor fixed wiring where 90-minute functional survivability is legally required for emergency installations:

• Smoke Clearance & Pressurization: Power circuits feeding major smoke exhaust fans, motorized smoke dampers, and staircase pressurization blowers in complex buildings.
• Fire Suppression Infrastructure: Operational feeds for primary fire booster pumps, sprinkler pump stations, and deluge systems.
• Emergency Evacuation & Lifts: Power supply lines for dedicated fire brigade evacuation elevators and central emergency operation panels.
• High-Occupancy Public Buildings: Underground metro networks, railway passenger terminals, international airports, hospitals, and hyperscale data centers (strictly for indoor routing; not permitted for direct burial in soil or water).

Frequently Asked Questions

Q: What is the fundamental difference between the E90 and E30 circuit integrity ratings?
A: E30 guarantees system electrical operation for 30 minutes, which is sufficient for alarm signals and evacuation lighting, whereas E90 guarantees functional operation for 90 minutes under fire conditions, which is required for heavy smoke extract fans, fire pumps, and fire-fighting lifts.

Q: Can NHXCH FE180-E90 cable be installed outdoors or buried underground?
A: No, standard specification guidelines explicitly dictate that these safety cables are engineered for indoor installations and are not suitable for direct burial in the ground or immersion in water.

Q: What is the primary role of the concentric copper conductor?
A: The concentric conductor of helical copper wires and counter-helical copper tape serves as a low-impedance protective earth (PE) or neutral conductor while providing continuous electromagnetic shielding (EMC) against high-frequency interference.

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