Applications & Installation
This single-core HFFR wire is specifically intended for internal wiring within distribution panels, electrical switchboards, and conduits, as well as surface-mounted or embedded installations in dry environments. Due to its low smoke and zero halogen (LSZH) properties, it is heavily specified for installations in high-occupancy public buildings, transportation hubs, hospitals, and high-rise commercial complexes where life safety and asset protection are paramount.
Standards & Compliance
Manufactured in accordance with TS EN 50525-3-31, the cable satisfies stringent European Construction Products Regulation (CPR) requirements with a classification of Cca-s1, d2, a1. It is entirely free of halogen compounds, ensuring zero corrosive gas emissions during combustion and reduced smoke propagation to maintain visibility along evacuation routes.
