Applications & Installation
This single-core HFFR cable is ideally suited for internal wiring of electrical switchboards, control panels, and appliances, as well as fixed installation in conduits, trunking, and under-plaster applications. Due to its advanced Cca-s1, d2, a1 Construction Products Regulation (CPR) rating, it is heavily specified for buildings with high concentrations of people and high-value assets—such as hospitals, airports, educational institutions, high-rise residential complexes, and commercial data centers—where smoke visibility and low toxicity during a fire are critical design parameters.
Standards & Compliance
The H07Z1-K 16 mm² cable strictly adheres to the TS EN 50525-3-31 standard. Its HFFR compound formulation guarantees compliance with stringent environmental and safety benchmarks, emitting virtually no corrosive gases or dense smoke during combustion. The cable meets the rigorous Cca-s1, d2, a1 CPR classification, verifying its low heat release, superior smoke production limitation (s1), low droplet formation (d2), and minimal acidity levels (a1).
