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
- 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
- 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
- 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
