Frequently Asked Questions
What is low-voltage LSZH flame-retardant unarmoured cable?
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.
Why choose LSZH for flame-retardant cables?
LSZH materials minimize toxic fumes and corrosive gases during fires, ensuring safer evacuation and reduced equipment damage (PH≥4.3, conductivity≤10μS/mm).
Where are they typically used?
High-rise buildings, subways, hospitals, and data centers where fire safety and low smoke emission are critical.
How does the flame-retardant mechanism work?
The cable's cross-linked polyethylene (XLPE) insulation suppresses flame spread, achieving Class B/C per GB/T 18380.3.
What's the temperature resistance range?
Operating temperature: -20°C to 90°C (standard) or up to 105°C.
Can these cables replace armored cables in hazardous areas?
No. Unarmoured versions lack mechanical protection; use only in environments without crushing risks.
