Applications & Installation
This single-core HFFR cable is ideally suited for internal wiring within distribution panels, switchgear, lighting fixtures, and electrical appliances. Because of its halogen-free properties, it is frequently specified for installations in public buildings, hospitals, schools, transport hubs, high-rise complexes, and enclosed spaces where dense smoke or toxic emissions present a severe hazard during fire emergencies. It is designed for installation in conduits on or under plaster, and in closed installation ducts.
Standards & Compliance
The H07Z1-K 4 mm² cable is manufactured in strict accordance with international quality benchmarks and regulatory frameworks. It complies with the TS EN 50525-3-31 standard and meets the European Construction Products Regulation (CPR) Eca reaction-to-fire performance class, making it fully certified for global trade and cross-border engineering projects.
