Engineered for Survival: Shanghai Shenghua’s Fire Resistant Cables for Critical Infrastructure​​

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​​

Packing and shipping

We are capable of meeting the most strict delivery schedules according to per purchase order. Meeting the deadline is always the top priority as any delay in the delivery of cable can contribute to overall project delay and cost overrun.
Cable is supplied in wooden reels, corrugated boxes and coils. Cable ends are sealed with BOPP self adhesive tape and non-hygroscopic sealing caps to protect the cable ends from moisture. The required marking shall be printed with a weather-proof material on the outsides of drum according to customer's requirement.
