At 3 a.m. in June 2020, a massive fire broke out at a cinema in a first-tier city, instantly engulfing the entire theater with thick smoke. Audiences panicked, some even fainted from suffocation. But in this crucial moment, a lifeline suddenly appeared: low-smoke, halogen-free cables. They prevented the spread of fire and smoke. 42-year-old cinema manager Li Ge relied on this undiscovered technology to save thousands of lives.
Why are low-smoke, halogen-free cables called the “invisible heroes” of cinemas?
Every cable in a cinema works silently in the shadows, but in the event of a fire, ordinary cables release highly toxic smoke that can instantly take lives! TST CABLE low-smoke, halogen-free cables are designed for these extreme scenarios:
1. The key to saving lives in a fire: 90% less smoke!
When ordinary PVC cables burn, they release deadly chlorine gas. Thick smoke obscures escape routes, leading to asphyxiation mortality rates as high as 70%. However, low-smoke halogen-free cables (such as TST CABLE WDZA-YJY) produce only a small amount of white smoke when burned, and their light transmittance exceeds 80%, allowing viewers to clearly see their escape routes!
Real Case Study:
After a cinema switched to low-smoke halogen-free cables, smoke concentrations during a fire simulation were only one-third of those observed with traditional cables! Firefighters commented, “That amount of smoke was enough for everyone to escape the building!”
2. Non-toxic and harmless, even breathing safe!
Halogen gases (such as hydrogen chloride) released when ordinary cables burn can corrode the respiratory tract and even cause chemical poisoning. However, low-smoke halogen-free cables contain no halogens, lead, or cadmium, making them non-toxic and harmless. Firefighters don’t even need to wear gas masks!
Real-World Scenario:
In 2025, a fire broke out in an IMAX theater. Thanks to TST CABLE’s WDZN-YJE22 fire-resistant low-smoke, halogen-free cable, the fire was contained within one minute, resulting in no casualties!
3. High-Temperature Resistant and Flame-Retardant, 180-Minute No-Fusing!
Ordinary cables melt rapidly at high temperatures, causing circuit failure! However, TST CABLE’s low-smoke, halogen-free cables (such as N2XH-FE 180/E 30) can maintain power for 180 minutes under direct flames, ensuring the proper functioning of firefighting equipment and emergency lighting!
Technical Core:
Mica Tape Fireproof Layer: Resistant to temperatures up to 105°C
Cross-Linked Polyolefin Insulation: Burns without dripping
Orange Jacket: Instantly Recognizable as a “Safety Wire”
Three Safety Tips for Theater Managers
1. Main Power Cord: Double-Insulated! Standard screening rooms: One TST CABLE WDZA-YJY-516 low-smoke, halogen-free, flame-retardant cable is sufficient.
IMAX theaters: Two cables (WDZA-YJY-516 + WDZA-YJY-425 + 1) are required to ensure stable power supply for high-power equipment!
2. Lighting wiring: Don’t use “cheap” cables!
Recommended model: TST CABLE WDZ-RYJ-105 (high-temperature resistant to 105°C) low-smoke, halogen-free, flame-retardant cable.
Installation method: Metal pipe + cable tray. Choose ZC flame retardant grade (highest flame retardancy).
3. Emergency system: Life-or-death!
Emergency lighting cable: Must use TST CABLE WDZN-YJE22 low-smoke, halogen-free cable. Steel-belt armored design, mechanical damage resistance, and 180-minute fire resistance.
Ground resistance: ≤1Ω (shared ground) to prevent electric shock!
Why not replace it now? Wait even a day, and the potential risks will escalate!
Policy Mandate: Starting in 2025, cinemas nationwide must use 100% low-smoke, halogen-free cable (GB 50169 standard)!
Cost Comparison: Only 3 yuan more per meter, but saves tens of millions in compensation!
Recommended Suppliers: TST Cable, TST Seal
“Even though cables are small, they can mean the difference between life and death! Don’t wait for tragedy to happen before regretting not replacing them—TST Cable, low-smoke, halogen-free cable, is the ultimate sense of security cinemas deserve!” Click to read and share this information to remind others you care about!
