The cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial,aerial supported by a messenger, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation in wet and dry locations, 130°C for emergency overload, and 250°C for short circuit conditions

Q.What is low-voltage LSZH flame-retardant unarmored cable?
A. A cable designed for circuits below 1kV, featuring Low Smoke Zero Halogen (LSZH) materials, flame-retardant properties, and no metallic armor layer. Ideal for indoor installations requiring enhanced fire safety
Q.Why choose LSZH for flame-retardant cables?
A. LSZH materials minimize toxic fumes and corrosive gases during fires, ensuring safer evacuation and reduced equipment damage (PH≥4.3, conductivity≤10μS/mm)
Q. Where are they typically used?
A. High-rise buildings, subways, hospitals, and data centers where fire safety and low smoke emission are critical
Q. How does the flame-retardant mechanism work?
A. The cable’s cross-linked polyethylene (XLPE) insulation suppresses flame spread, achieving Class B/C per GB/T 18380.3
Q. What’s the temperature resistance range?
A. Operating temperature: -20°C to 90°C (standard) or up to 105°C
Q. Can these cables replace armored cables in hazardous areas?
A. No. Unarmored versions lack mechanical protection; use only in environments without crushing risks
