Fire-resistant power cable (N)HXH-J FE180/E90 5x25 1kV G-144798

Fire-resistant power cable – safety and reliability of installation

This power cable (N)HXH-J FE180/E90 is a proposal for demanding installations where maintaining power continuity even in the event of a fire is crucial. Designed for operation in 1kV systems, it is characterized by high fire and temperature resistance, ensuring protection for both the installation and users. It is an ideal solution for public buildings, industrial facilities, and anywhere where higher safety standards are required.

Construction and properties

The cable is made of copper conductors with a cross-section of 25 mm², which guarantees efficient current conduction. The conductor insulation is made of a material meeting safety standards, and the outer sheath made of polyethylene provides resistance to mechanical damage and weathering. It is worth noting the lack of armor – which affects the cable's flexibility and facilitates its installation. Additionally, the cable has a certificate confirming its fire resistance in accordance with IEC 60332-1-2 and maintaining function for 90 minutes in accordance with IEC 60331-1. These are key parameters for installers designing fire protection systems.

• Fire resistance: Class FE180/E90 ensures maintaining circuit continuity for at least 90 minutes in fire conditions, which is critical for alarm, evacuation and fire-fighting systems.
• Halogen-free: Compliance with IEC 60754-1 and IEC 60754-2 standards guarantees the absence of toxic gas emissions during combustion, which increases user safety in the event of a fire.
• UV resistance: Thanks to its UV resistance, the cable can also be used in outdoor installations without the risk of material degradation.
• Flexibility: The lack of armor makes it easier to lay the cable in tight spaces and reduces installation time.
• Conductor cross-section: The large conductor cross-section (25 mm²) minimizes voltage drop over long cable lengths and allows for the transmission of higher currents.
• Operating temperature: A wide range of permissible operating temperatures (-40°C to +70°C) allows the cable to be used in various environmental conditions.

Applications and compliance with standards

The (N)HXH-J FE180/E90 cable is primarily used in electrical installations requiring a high level of fire safety. It is ideally suited for:

• Public buildings (hospitals, schools, office buildings).
• Industrial facilities (factories, warehouses).
• Tunnels and underground engineering structures.
• Alarm and fire protection systems.
• Power supplies for rescue equipment.

The cable meets the requirements of IEC 60332-1-2 (fire resistance) and IEC 60331-1 (function maintenance) standards, guaranteeing its compliance with applicable regulations and safety standards. Additionally, it has color-coded conductor identification according to HD 308 S2, which facilitates installation work.
