Why is the halogen-free, flame-retardant (HFFR) property essential for modern installations?

HFFR materials do not emit corrosive halogen gases or dense black smoke when exposed to fire, which is critical for protecting human life, sensitive electronic equipment, and building structures. In confined public spaces like hospitals, airports, and subway systems, cables complying with IEC 60754 (halogen content) and IEC 61034 (smoke density) dramatically improve evacuation visibility and reduce secondary damage. These fire safety characteristics are mandatory under the Construction Products Regulation (CPR) in Europe and are a core requirement for any power cable deployed in areas with high personnel concentration or strict environmental control.
