EN 60332-3-24 NHXH FE180-E90 0.6/1kV Cable - 1.5mm² to 300mm²

Description

EN 60332-3-24 NHXH FE180 is a low-voltage, low-smoke zero-halogen fire-safety and circuit-integrity power cable engineered to maintain electrical functionality during a fire to protect human life and essential infrastructure. The cable features a class one solid or class two stranded bare annealed copper core insulated with a cross-linked halogen-free polymer, which is protected by a high-performance, flame-resistant glass-mica tape or a specialised ceramic compound layer extruded directly over the conductors. Multi-core variants are bound symmetrically with a flame-retardant, halogen-free filler layer in a heavy-duty, thermoplastic polyolefin outer sheath. This specialized construction keeps emergency power networks live under extreme heat conditions, making it uniquely suited for powering critical systems such as smoke extraction fans, emergency lighting, and evacuation elevators in public safety environments including hospitals, airports, underground railway networks, data centres, and shopping complexes.

This cable complies with EN 60332-3-24 standard for category C bunched flame-spread resistance. It features an insulation integrity rating of FE180, guaranteeing that the cable core insulation will remain intact for at least 3 hours of direct fire exposure under testing standard conditions. It is a low-voltage rated cable of 0.6/1 kV. The non-corrosive, LSZH formulation ensures that minimal toxic fumes and acidic gases are emitted during a fire event, maximizing visibility and breathing safety along critical evacuation routes.

Installers must maintain standard minimum bending radius of at least twelve times the overall cable diameter for multi-core configurations and fifteen times the overall diameter for single-core layouts during standard routing and active pulling. Maximum pulling stress margins must never be exceeded during line layouts to avoid warping the internal fire barrier wrapping. The cable is designed strictly for indoor or above-ground external usage. Fire resistant to FE 180 and Circuit Integrity to E90.
