Applications & Installation
This 185 mm² single-core HFFR cable is ideally suited for internal wiring in switchgear, control gear, conduit installations, and under-plaster applications in dry environments. Due to its Low Smoke Zero Halogen (LSZH) properties, it is heavily specified by electrical contractors and procurement managers for public buildings, hospitals, schools, transportation hubs, high-rise residential complexes, and industrial plants where smoke density and toxic gas emissions must be strictly limited.
Standards & Compliance
The H07Z1-K cable series complies with rigorous European and international standards. It meets the requirements of TS EN 50525-3-31 for low voltage energy cables with thermoplastic insulation and special fire performance. The insulation compound is verified for low smoke emission (IEC 61034) and absence of halogen acids (IEC 60754), satisfying Construction Products Regulation (CPR) class Eca compliance for international trade and export compliance.
