Halogen-free power cable NHXCH FE180/E90 3x70 RM/35 B61425

Halogen-free power cable NHXCH FE180/E90 3x70 RM/35

This fire-resistant, halogen-free power cable with a concentric conductor, manufactured by BITNER, is a solid solution for installations requiring high safety and reliability. The NHXCH FE180/E90 3x70 RM/35 cable is designed for power transmission in places with increased fire protection requirements.

Construction and application

This cable is characterized by a construction that provides fire resistance and the absence of toxic gas emissions during combustion – crucial in the event of a fire, especially in public buildings or industrial facilities. It is intended for use in fixed and mobile installations, both indoors and outdoors (provided protection against UV radiation). Thanks to the copper working conductors of class 1 or 2 (according to EN 60228 and IEC 60228 standards), it ensures efficient current conduction.

Key features and benefits

• Halogen-free: The absence of halogen in the insulation means no emission of toxic and corrosive gases during a fire, which increases the safety of people and equipment. This is particularly important in enclosed spaces where smoke can pose a serious threat.
• Fire resistance: Meets the requirements of IEC 60331, which guarantees maintaining the continuity of the electrical circuit during a fire for a specified time.
• Maintenance of electrical functions: Compliance with EN 50200 and DIN 4102-12 ensures maintaining the electrical functions of the cable during a fire – crucial for fire protection, alarm and evacuation systems.
• Wide operating temperature range: The ability to operate at a temperature of -5°C to +90°C (fixed installation) and from -5°C to +50°C (mobile installations) makes the cable versatile and can be used in various environmental conditions.
• Thermal resistance: The maximum conductor temperature during operation is 90°C, and during a short circuit (up to 5 seconds) – as much as 250°C, which ensures long-term and safe operation.
• Flexibility: Despite its solid construction, the cable retains adequate flexibility, making installation and routing easier.
• Conductor cross-section: The conductor cross-section of 70 mm² allows for the transmission of large currents, making it ideal for powering devices with high power consumption.

Technical parameters

The NHXCH FE180/E90 cable has the following parameters:

• Number of cores: 3
• Nominal conductor cross-section: 70 mm²
• Operating voltage: 0.6/1kV
• Test voltage: 4kV
• Minimum bending radius (fixed connection): 15 x cable diameter
• Weight per kilometer: approx. 3382 kg/km (for 3x70 mm² cable)

This cable is an investment in the safety and reliability of your electrical installation. This is especially important in places with an increased risk of fire or where protection against the emission of toxic gases is required.
