Halogen-free cable NHXMH-J 500V 5x2.5 white NHXMH-J5-5X2,5

Halogen-free cables – safety and installation reliability

The NHXMH-J 5x2.5 cable is an advanced solution for electrical installations where safety and fire protection are paramount. Its halogen-free construction minimizes the emission of toxic gases during combustion, making it essential for public buildings such as hospitals, schools, and hotels, as well as for industrial and residential installations. This cable is designed for installation in dry and humid environments, under plaster, in masonry walls, and directly in concrete—always in accordance with fixed installation standards.

The NHXMH-J cable features flexibility thanks to stranded copper conductors with a cross-section of 2.5 mm², facilitating installation and routing in confined spaces. The insulation, made of cross-linked polyethylene (XLPE), ensures high resistance to mechanical and thermal damage. The absence of armor or reinforcement makes the cable lighter and easier to handle, a feature appreciated by installers. The outer sheath, made of polyolefin, further enhances durability and resistance to external factors.

• Fire safety: Halogen-free sheath minimizes toxic gas emissions during fire, protecting users’ health and lives.
• Versatile application: Suitable for installations in diverse environments—from dry rooms to humid industrial settings.
• Easy installation: Stranded conductors simplify cable routing even under challenging conditions.
• Durability: Constructed from high-quality materials—copper and cross-linked polyethylene—ensuring long-term, reliable performance.
• Compliance with standards: Meets requirements of EN 60332-1-2 standard regarding flame propagation resistance.

Operating parameters and construction

The NHXMH-J 5x2.5 cable is designed for operation at a rated voltage of 500 V (U) and 600 V (U0). The maximum allowable conductor operating temperature is 70°C, and the minimum bending radius for fixed installations is 132 mm—this must be considered when designing the cable route. The approximate outer diameter is 11 mm, and the weight is approximately 225 kg/km. The conductor color coding (multiple colors) facilitates identification during installation. It is also important to note the permitted ambient temperature range during installation: from -5°C to +5°C.

This cable does not include a screen or protective barrier, which contributes to its reduced weight and increased flexibility. The absence of an earth conductor must be taken into account when designing the protective earthing system. The conductor class is Class 1 (solid core), indicating greater rigidity compared to multi-strand conductors. The use of high-quality materials ensures resistance to atmospheric and chemical conditions (although the cable is not oil-resistant or suitable for low-temperature environments).
