TT Cables NHXH-J RE/SP FE180/E90 Fire Resistant Power Cable, 4 x 2.5mm², 500m

The TT Cables NHXH-J RE/SP FE180/E90 is a specialized fire-resistant power cable engineered to maintain electrical circuit integrity in the event of a fire. With a configuration of 4 conductors, each with a cross-section of 2.5mm², this cable is designed for demanding environments where safety and reliability are paramount. The orange-colored outer sheath allows for easy identification as a safety-critical component within complex electrical infrastructures.

Advantages

This cable offers exceptional performance in emergency situations by providing FE180 insulation integrity, which ensures the cable remains functional for at least 180 minutes during exposure to fire. Furthermore, it meets E90 functional maintenance standards, guaranteeing that connected safety systems remain operational for 90 minutes under fire conditions. The robust construction ensures durability and consistent power delivery, making it a reliable choice for critical building management systems.

Suitable for

• Emergency lighting systems in public buildings
• Fire alarm and detection installations
• Smoke extraction and ventilation control systems
• Safety-critical power supply in industrial facilities
• Evacuation guidance and communication systems

This cable is not intended for standard residential wiring where fire-resistant properties are not required, as its specialized construction makes it more rigid and costly than conventional power cables. It is also not suitable for direct burial or underwater applications unless additional protective measures are implemented.

Key specifications

• Conductor cross-section: 2.5 mm²
• Number of conductors: 4
• Fire resistance rating: FE180 (insulation integrity)
• Functional maintenance: E90 (90 minutes)
• Cable shape: Hose
• Color: Orange
• Flammability class: Eca
• Package length: 500 m

How to use

Installation should be performed by qualified electrical professionals in accordance with local fire safety regulations and electrical codes. The cable is typically routed through cable trays, conduits, or fixed directly to walls using appropriate mounting hardware that maintains the fire-resistant integrity of the installation path. Ensure that the bending radius is respected during installation to prevent damage to the internal insulation layers.

What to consider before purchase

• Verify the specific fire safety requirements of your local building codes.
• Ensure the 2.5mm² cross-section is sufficient for the total load of your connected equipment.
• Confirm that the installation environment is compatible with the cable's physical properties.
• Check the total length required for your project against the 500m package size.

Usage recommendations: Always handle the cable with care during installation to avoid kinking or crushing the outer sheath. Ensure all connections are made using fire-rated junction boxes and terminals to maintain the overall system's E90 rating.
