Fire-resistant power cable (N)HXH-O FE180/E90 1x185 RE 1kv G-144981

Advanced fire-resistant cable for safety installations

The fire-resistant power cable (N)HXH-O FE180/E90 1x185 RE 1kV is an advanced conductor designed for systems where safety and power continuity are of paramount importance.

Construction and materials ensuring maximum safety

The conductor is made of class 2 copper (stranded) with a cross-section of 185 mm², enabling the transmission of large currents at voltages up to 1 kV. The single-core construction simplifies installation and minimizes the risk of mounting errors.

The cable insulation is made of halogen-free materials, which guarantees minimal emission of toxic gases during a fire. The outer sheath made of polyolefin provides mechanical and chemical resistance. The cable meets the requirements of IEC 60754-1 and IEC 60754-2 standards, confirming its full halogen-free properties.

The outer diameter is 24.3 mm, and the minimum bending radius is 364.5 mm. The cable weight is 1986 kg/km, which testifies to its robust construction while maintaining reasonable installation flexibility.

Fire-resistant properties and operating parameters

The key feature of the product is the maintenance of function for 90 minutes during a fire (IEC 60331-1 parameter), which determines the safety of the entire installation.

The cable operates in a wide temperature range: from -40°C to +70°C after installation and from -15°C to +70°C during installation. The maximum conductor temperature is 90°C, enabling operation in industrial conditions.

The conductor resistance at 20°C is only 0.0991 Ω/km, ensuring minimal energy losses even at high currents. Conductor identification is carried out by color in accordance with the HD 308 S2 standard.

Application in safety systems and critical installations

The (N)HXH-O FE180/E90 conductor is ideal for emergency lighting installations, alarm systems, and powering critical loads in industrial and commercial facilities.

Thanks to low smoke emission (IEC 61034-2 standard), the cable does not degrade evacuation conditions during a fire. It is particularly recommended for public utility buildings, hospitals, schools, and industrial plants with high fire risk.

The cable is suitable as an installation conductor according to technical standards, but its primary function is to ensure power continuity in emergency situations. The manufacturer Telefonika guarantees high manufacturing quality and compliance with all required European standards.
