Applications & Installation
This single-core HFFR cable is ideally suited for internal wiring in public buildings, hospitals, schools, transit systems, and high-rise commercial developments where safety-critical circuits and human life protection are paramount. Its low smoke density and absence of corrosive gases prevent secondary damage to sensitive electronic equipment and structural infrastructure during a fire event. It is intended for installation in closed conduit systems or trunking.
Standards & Compliance
Manufactured in strict adherence to TS EN 50525-3-31, the cable meets rigorous European harmonization standards for low-voltage energy cables. Under the Construction Products Regulation (CPR), it achieves a Cca-s1, d2, a1 rating, certifying exceptional flame propagation resistance, minimal smoke production, and negligible acidity of combustion gases.
