NEN 1010 §521.9
Fire-resistant cable (NHXH / FE180)
Brandveilige kabel (NHXH / FE180 E30)
Also known as: nhxh, fe180, brandveilige-kabel, fire-resistant-cable, halogeenvrije-kabel, halogen-free-cable, noodverlichting-kabel
Halogen-free, flame-retardant cable (NHXH / FE180) maintaining functionality for 30–90 minutes during fire (FE30/FE60/FE90). Mandatory for safety installations like emergency lighting, fire alarm panels, sprinkler pumps, and smoke extraction. No chlorine or bromine sheath — no hydrochloric acid fumes when burning.
Practical example
Fire-safe cable (NHXH / FE180 E30). The emergency lighting and smoke extraction wiring in an office building is installed in NHXH FE90, ensuring 90 minutes of operation during fire.
Common mistake
Fire-safe cable (NHXH / FE180 E30). Common mistake: Using standard YMvK for emergency lighting — in a fire, the sheath melts, causing the safety system to fail exactly when needed.
