Fire-resistant power cable NHXHX-J FE180 PH90/E90 0.6/1 kV 5x16 RE 1391 134 33

Fire-resistant power cable – safety and reliability in critical installations

This fire-resistant power cable, marked as NHXHX-J FE180 PH90/E90 0,6/1 kV 5x16 RE, is designed to ensure continuous power supply during emergency situations, particularly where high fire resistance and maintained functionality over a specified time are required. It is a critical solution for public utility buildings, data centers, hospitals, and other facilities with elevated safety requirements.

This cable is used in electrical installations where the priority is protecting human life and property from fire hazards. Its construction and materials guarantee the continuity of the electrical circuit even under extreme conditions.

Construction and properties

The cable consists of five copper conductors, each with a cross-section of 16 mm², made from soft strands (RE – single-wire round, Class 1). The conductor insulation is made of cross-linked halogen-free material, minimizing the emission of toxic gases during a fire. The outer sheath is also made of halogen-free material, further enhancing safety.

Pay attention to the designations FE180 and PH90/E90, which indicate the cable’s high fire resistance. FE180 means the ability to maintain circuit continuity for 180 minutes under fire conditions, while PH90/E90 guarantees functional integrity for 90 minutes during fire exposure with simultaneous flame impact (PH) and exposure to hot gases and heat (E).

Additional cable features:

• Halogen-free: Compliance with EN 50267-2-2 and IEC 60754-2 standards, resulting in reduced toxicity of emitted gases during combustion.
• Temperature resistance: Maximum conductor operating temperature of 90°C and ambient temperature up to 70°C (without vibration), ensuring reliable performance under various operating conditions.
• Low smoke emission: Class s2 according to EN 13501-6, and compliance with EN 61034-2 and IEC 61034-2 standards confirm minimal smoke emission during fire.
• Fire reaction class: B2ca according to EN 13501-6 ensures adequate fire protection level.
• Sheath color: Orange facilitates identification of the cable as fire-resistant.

This cable is an investment in the safety and reliability of electrical installations, especially where requirements are highest. Its advanced construction and quality certifications guarantee protection against fire consequences and ensure continuous power supply in critical situations.
