Fire-resistant power cable NHXH-J FE180 PH90/E90 0.6/1 kV 3x70 RM orange 0699 074 33

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

This three-core power cable with a cross-section of 70 mm² is designed for installations requiring the highest level of fire safety. Made of high-quality materials, it meets stringent standards for fire resistance and emission of harmful substances during a fire. Ideal for use in public buildings, tunnels, hospitals and other facilities where uninterrupted power supply in emergency situations is crucial.

Construction and properties

The NHXH-J FE180 PH90/E90 cable stands out with its advanced construction ensuring reliable operation even in extreme conditions. Its structure includes:

• Cores: Made of soft copper strands, compliant with PN-EN 60228 standard (available in RE – solid core and RM – stranded version). This ensures flexibility and ease of installation.
• Insulation: Made of cross-linked halogen-free plastic, guaranteeing high resistance to temperature and chemical factors. The insulation colors of the cores are compliant with PN-HD 308 standard or marked with white numbers on a black background. In the NHXH-J cable, the protective green-yellow core is located in the outer layer.
• Core: Stranded cores layered in a core for better protection against mechanical damage.
• Filling: Filling layer made of halogen-free material, stabilizing the cable structure.
• Sheath: Made of halogen-free material (HFFR) with HM4 properties according to PN-HD 604 S1, providing minimal emission of smoke and toxic gases in case of fire and resistance to UV radiation. The sheath color is orange for easy identification.

Applications and benefits

This cable is used primarily in electrical installations requiring high fire resistance, such as:

• Fire protection systems (power supply for water pumps, smoke extractors, emergency lighting).
• Public buildings (hospitals, schools, shopping centers).
• Tunnels and infrastructure facilities.
• Installations in places with increased fire risk.

Thanks to its properties, the cable provides:

• People safety: Minimal emission of toxic gases and smoke during a fire.
• Continuous operation: Maintaining power to critical devices during evacuation and firefighting (up to 90 minutes – PH90/E90).
• Resistance to external conditions: Possibility of use both indoors and outdoors, as well as resistance to UV radiation. Additional protection allows for laying the cable in water and soil.
• Compliance with standards: It has a Certificate of Conformity and an Approval Certificate from the Scientific Research Centre for Fire Protection - PIB in Józefów.
