TT Cables NHXH-J RE/SP FE180/E90 Fire Resistant Power Cable, 3 x 1.5mm², 500m

The TT Cables NHXH-J RE/SP FE180/E90 is a high-performance, halogen-free power cable engineered specifically for environments where maintaining electrical circuit integrity during a fire is critical. This 3-core cable with a 1.5mm² cross-section is designed to provide reliable power transmission in emergency systems, ensuring that essential equipment remains operational under extreme thermal stress. Its robust construction and specialized materials make it a standard choice for safety-critical infrastructure.

Advantages

This cable offers exceptional fire resistance, maintaining insulation integrity for up to 180 minutes and full system functionality for 90 minutes during exposure to fire. Being halogen-free, it significantly reduces the emission of toxic gases and smoke in the event of a fire, which is vital for the safety of occupants in public buildings. The orange outer sheath allows for easy identification as a fire-resistant component within complex electrical installations, while the solid conductor design ensures durability and consistent performance over long distances.

Suitable for

• Fire alarm and detection systems
• Emergency lighting installations
• Public buildings such as hospitals, schools, and shopping centers
• Critical power supply for ventilation and smoke extraction systems
• Infrastructure requiring E90 circuit integrity standards

This cable is not intended for use in environments where it will be subjected to constant mechanical movement or high-vibration machinery, as it is designed for fixed installations. It is also not suitable for direct burial in soil without additional protective conduit or mechanical shielding.

Key specifications

• Number of conductors: 3
• Conductor cross-section: 1.5 mm²
• Fire resistance rating: FE180 (insulation integrity) / E90 (system functionality)
• Material properties: Halogen-free
• Flammability class: Eca
• Cable shape: Round (hose)
• Color: Orange
• Total length: 500 m

How to use

The cable should be installed in accordance with local electrical regulations for fire-resistant systems. It is designed for fixed installation in dry or damp indoor environments, as well as outdoors if protected from direct sunlight and mechanical damage. When routing the cable, ensure that the minimum bending radius is respected to avoid damaging the internal insulation layers. Connections should be made using appropriate fire-rated junction boxes and terminals to ensure the entire circuit maintains its E90 rating.

What to consider before purchase

• Verify that the 1.5mm² cross-section is sufficient for the total current load of your specific application.
• Ensure the installation environment complies with the Eca flammability class requirements.
• Confirm that the 500m length is appropriate for your project requirements.
• Check that all supporting components, such as cable trays and fixings, are also fire-rated to match the cable's performance.

Usage recommendations

Always consult with a certified electrical engineer to ensure the cable selection meets the specific fire safety codes and load requirements of your building project. Proper installation techniques are essential to guarantee the FE180/E90 performance rating.
