Shenghua BS5308 XLPE-OS-LSOH Cable | Zero Toxic Smoke in Industrial Fires

​​When a chemical plant fire in Jiangsu in 2023 released 300ppm HCl gas—5x above safety thresholds—emergency systems failed due to PVC cable toxicity​​. Shenghua’s ​​BS5308 XLPE-OS-LSOH Shielded Instrument Cables​​ are engineered to prevent such disasters, combining IEC-certified flame retardancy with zero-halogen innovation.

​​Why Traditional Cables Become "Silent Killers" in Fires​​

• ​​Toxic Gas Emission​​: PVC sheaths release ​​hydrogen cyanide (HCN) at 300°C​​—135ppm concentration is lethal within minutes
  .
• ​​Signal Failure​​: Aluminum screens melt at 650°C, causing critical control systems to fail
  .

​​Shenghua’s Triple-Shield Defense​​

​​1. LSOH Sheath (IEC 60754-1)​​:
Halogen-free compounds reduce smoke density to ​​<5% opacity​​ (vs. 80%+ for PVC), improving visibility by 16x during evacuations

.
​​2. XLPE Insulation + Mica Tape​​:
Withstands 90°C continuous heat and 160°C short-circuit arcs without releasing corrosive gases

.
​​3. Al-Polyester Collective Screen​​:
Metal-side-down tape + 0.5mm² tinned copper drain wire maintains ​​EMI shielding at 950°C​​ (BS 6387 Class C)

.

​​Case Study: Zhejiang Petrochemical Plant Retrofit​​

After replacing legacy cables with Shenghua’s solution:

• ​​Evacuation time dropped 37%​​ in fire drills (no smoke obstruction).
• ​​Instrument false alarms reduced 92%​​ (stable EMI shielding in high-voltage zones)
