Frequently Asked Questions
What is LSZH Silicon Fire Alarm Cable?
A flame-retardant cable with low-smoke, zero-halogen (LSZH) silicone insulation, designed to minimize toxic gas emission and smoke density during fires while maintaining circuit integrity.
Where are these cables typically used?
Critical environments like subways, hospitals, data centers, and high-rise buildings where fire safety and air quality during emergencies are prioritized.
How does the LSZH silicone material enhance safety?
It releases minimal smoke and no corrosive halogens when burned, reducing visibility obstruction and secondary harm to equipment/personnel.
What certifications do these cables comply with?
Common standards include EN50200 (PH30/PH120), BS6387 (CWZ), and CE/ROHS for fire resistance and environmental safety.
Can they withstand high temperatures?
Yes, silicone insulation allows continuous operation at 90°C and short-term resistance up to 850°C during fire exposure.
What conductor materials are available?
Options include bare copper (BC), tinned copper (TC), or copper-clad aluminum (CCA), with stranded/solid variants for flexibility or rigidity.
Are these cables suitable for outdoor use?
Yes, when paired with UV-resistant jackets, they can be deployed in renewable energy projects or exposed industrial settings.
How do they compare to PVC-jacketed fire cables?
LSZH silicone cables outperform PVC in smoke suppression (
What is the lifespan under normal conditions?
Typically 25+ years due to silicone's resistance to thermal aging, ozone, and chemicals.
