In high-risk environments like hospitals, metro tunnels, and petrochemical plants, circuit integrity during fires is non-negotiable. Shanghai Shenghua Power Group Cable addresses this with its FRC 4-Core LSOH Fire Resistant Cables—designed to maintain power transmission even at 1,000°C for 90+ minutes while emitting zero toxic smoke.

Core Technology: Triple-Layer Fire Defense

1. Mica Tape Firewall: Wrapped around copper conductors, mica tape withstands 250°C during 5-second short circuits and 750°C+ in prolonged fires, preventing conductor exposure and ensuring circuit integrity 
    
2. LSOH Insulation & Sheath: Halogen-free materials reduce toxic gas emissions (HCl <0.5%) and smoke density (>60% light transmittance), aligning with IEC 61034-2 and IEC 60754-1 
    
3. XLPE Thermal Stability: Cross-linked polyethylene insulation enables long-term operation at 90°C, outperforming PVC’s 70°C limit while resisting electrical degradation 
    

Certified Performance for Global Compliance

Shenghua’s cables exceed international safety benchmarks:

• Standards: IEC 60502, 60331 (fire resistance), 61034 (smoke density), and GB/T 12706 (China) 
   
• Certifications: CE, RoHS, CCC, and KEMA-tested reliability 
   
• Fire Ratings: Class ZA/ZB/ZC/ZD flame retardancy and 950°C fire resistance for emergency systems 
   

Installation & Durability Optimized

• Bending Flexibility: Multi-core cables require only 15× outer diameter bends, easing installation in tight spaces 
   
• Environmental Resilience: Operates at -0°C to 90°C (preheating below 0°C) and resists chemicals, oils, and mechanical stress 
   
• Water & Impact Resistance: Withstands sprinkler systems and falling debris during fires—critical for evacuation safety 
   

Applications Where Failure Is Not an Option

• High-Rise Buildings: Powers fire lifts, smoke control, and emergency lighting (e.g., NH-YJV32 variant) 
   
• Power Stations & Petrochemical Plants: Ensures uninterrupted operation of critical control systems 
   
• Metro Tunnels: LSOH properties aid visibility during evacuations 
   

Technical Specifications

Why Shenghua Stands Apart

• 30+ Years of Expertise: Custom solutions for complex projects (e.g., skyscrapers, offshore platforms) 
   
• Rigorous Testing: On-site fire labs validate circuit integrity under BS 7846 and BS 6387 standards 
   
• Global Supply: CE/RoHS-compliant production with 15-day delivery from Shanghai hubs
