Description MicroDucts LSZH from 5mm OD - 27 mm OD Dura-Line was the first to pioneer this technology and introduce it to the U.S. market. LSZH Conduit and MicroDucts, verified by the NRTL (Intertek) to ETL standards UL1685-4 and IEC 60754-1, exhibit excellent properties such as low-flame propagation, low-smoke generation, zero-halogen emissions, and excellent low-temperature mechanical properties. They are designed for use in applications where smoke, toxic fumes, and acidic gas pose a health risk and possible damage to electronic equipment. Examples include enclosed public areas and poorly ventilated areas such as tunnels, mass transit corridors, behind-the-wall, control rooms, and confined spaces.
