Product Overview
The H07Z1-K 70 mm² 450/750V cable is engineered for fixed protected installations in lighting systems, switchgear, control panels, and conduit piping. Featuring a fine-stranded bare copper conductor and advanced HFFR insulation, this product combines excellent electrical conductivity with superior environmental and safety performance. As a halogen-free solution, it prevents the release of toxic gases and corrosive acids, making it an essential requirement for modern infrastructural projects meeting stringent fire safety regulations.

Applications & Installation
The H07Z1-K 70 mm² HFFR cable is specifically designed for internal wiring within distribution boards, electrical appliances, and protective conduits mounted on or under plaster. Due to its Cca-s1, d2, a1 fire rating, it is heavily specified for installations in environments with high human density and valuable assets—such as hospitals, airports, railway stations, data centers, high-rise residential complexes, and commercial skyscrapers where smoke visibility and low toxicity are critical during evacuation.
Standards & Compliance
Complying fully with TS EN 50525-3-31, this cable satisfies international safety and quality benchmarks. The HFFR insulation guarantees zero halogen content (IEC 60754-1/2), low smoke density emission during combustion (IEC 61034-2), and flame propagation resistance (IEC 60332-1-2). Furthermore, its high-tier CPR classification (Cca-s1, d2, a1) aligns with strict European Union Construction Products Regulation frameworks, ensuring verified reliability for global B2B procurement and large-scale industrial tenders.
