TOXFREE® LSZH N2XH 1,8/3 kV cables provide superior flexibility and ensure fire-retardant, low-smoke, and halogen-free fire safety (B2ca, Cca) for public places and high rise buildings.
UK Building Regulations, European CPR and worldwide electrical national codes increasingly mandate LSZH cables in public spaces and high-occupancy buildings—making N2XH flex not just better performance, but often a regulatory requirement. Provide minimal smoke emission (enabling clearer evacuation routes and safer escape conditions during fires), prevent the release of corrosive or chlorine-based toxic gases, and reduces potential for smoke inhalation injuries. This cable is also available in its variants N2XH-J and N2XH-O.
TOXFREE® LSZH N2XH 1,8/3 kV cables provide superior flexibility (class 5) and ensure fire-retardant, low-smoke, and halogen-free fire safety (B2ca, Cca) for reliable power in high-risk industrial facilities and construction sites. XLPE insulation provides superior thermal performance (90°C continuous operation) and excellent electrical properties for demanding industrial loads. The LSZH outer sheath meets stringent UK, European and international fire safety standards (CPR B2ca and Cca).
This combination eliminates the need for separate cable specifications, simplifying procurement and ensuring compliance across UK, European and worldwide installations.
The LSZH outer sheath prevents corrosive halogen emissions that could damage sensitive servers, networking equipment, and storage systems worth millions. Minimal smoke production during fire incidents maintains visibility for emergency response and protects delicate electronic components. Class 5 flexibility facilitates installation through raised floors, cable trays, and tight server rack configurations. XLPE insulation ensures reliable 90°C operation under sustained high loads typical of data centre power distribution.
The N2XH-J 1,8/3 kV and N2XH-O 1,8/3 kV variants offer additional mechanical protection for demanding routing scenarios, making this cable family the strategic choice for mission-critical facilities.
