Product Overview
The H05Z1-U 4 mm² 450/750V is a premium single-core electrical installation cable engineered for fixed protected installations. Built with halogen-free, flame-retardant (HFFR) materials, this cable is specifically designed for environments where public safety, human life, and sensitive electronic equipment require high-level protection against toxic smoke and corrosive gases during a fire. It features a solid copper conductor providing reliable electrical conductivity and mechanical stability for conduit and trunking systems.

Applications & Installation
This single-core HFFR cable is ideally suited for internal wiring in buildings, public spaces, commercial complexes, and industrial facilities. It is recommended for installation in conduits, under and on surface-mounted wiring, and in enclosed lighting systems. Due to its superior fire behavior and low smoke density ratings, it is heavily specified for projects subject to strict building regulations, densely populated areas, and facilities with high concentration of assets.
Standards & Compliance
The H05Z1-U cable complies with rigorous international manufacturing and safety protocols. It strictly adheres to TS EN 50525-3-31 standards. Furthermore, its Construction Products Regulation (CPR) classification of Cca-s1, d2, a1 confirms its outstanding reaction to fire, minimal smoke production, absence of flaming droplets, and low acidity of combustion gases, making it a reliable choice for global B2B electrical export projects.
