Innovating Fire Safety: Shanghai Shenghua's Advanced Fire Resistant Cables for Critical Infrastructures​​

In high-risk environments like power plants, subways, and skyscrapers, ​​fire safety isn’t negotiable​​. A single cable failure during a fire can cascade into catastrophic losses. Shanghai Shenghua Power Group Cable addresses this with its ​​FRLS Fire Resistant Cables​​ – engineered to sustain power transmission even under extreme conditions.

​​Core Technology: The Science Behind Shenghua’s Fire Resistance​​

Shanghai Shenghua’s cables integrate multilayer fire-defense systems:

1. ​​Mica Tape Firewall​​: Wrapped around copper conductors, mica tape withstands temperatures up to ​​250°C​​ during short circuits (≤5s), preventing conductor exposure and maintaining circuit integrity 
   
   
2. ​​XLPE Insulation​​: Cross-linked polyethylene insulation ensures ​​long-term stability at 90°C​​, outperforming PVC’s 70°C limit while resisting electrical degradation 
   
   
3. ​​Halogen-Free Protection​​: LSOH/LSZH sheaths minimize toxic smoke and corrosive gases – critical for evacuation safety. Tests confirm ​​HCl emissions <5mg/g​​ (per IEC 60754-1) and ​​>60% light transmittance​​ (IEC 61034-1), surpassing low-smoke standards 
   
   

​​Certified Performance: Meeting Global Fire Safety Benchmarks​​

Shenghua’s cables comply with:

• ​​IEC 60331 & IEC 60502​​: Validating 90-minute circuit integrity under fire (FE180/E90 rating) 
  
  
• ​​UL Standards​​: Including CMP/CMR ratings for smoke density and flame spread control 
  
  
• ​​Multi-Core Flexibility​​: Available in 1C to 5C configurations (35mm² to 630mm²), with color-coded cores for error-proof installation 
  
  

​​Installation & Durability: Engineered for Real-World Demands​​

• ​​Extreme Environment Resilience​​: Resists chemicals, oils, and mechanical stress, suitable for mines, chemical plants, and subway tunnels 
  
  
• ​​Bending Radius Optimization​​: Armored multi-core cables require only ​​12× diameter​​ bends, reducing installation complexity 
  
  
• ​​Temperature Tolerance​​: Operates at ​​-0°C to 90°C​​ – preheating enables sub-zero deployment 
  
  

​​Why Shenghua Stands Out in Critical Applications​​

• ​​Case Study: High-Rise Safety​​: In skyscrapers, Shenghua’s ​​NH-YJV32 cables​​ power fire lifts and smoke extraction systems, ensuring 90+ minutes of emergency operation 
  
  
• ​​Supply Chain Assurance​​: CE/RoHS-certified production with 15-day delivery, supporting global projects from Shanghai to Dubai 
  
  

​​Partner with Shenghua for Uncompromised Fire Safety​​

Shanghai Shenghua Power Group Cable combines ​​material science, rigorous testing, and industrial expertise​​ to deliver cables that don’t just resist fire – they outlast it. With over 30 core specifications and global certifications, we empower infrastructures where failure is not an option.

Application

This type of fire resistant and flame retardant cable is suitable for power distribution lines with requirements of flame-retardant or fire-resistant fixed installations.

Application conditions

1. The long-time permissible operation temperature of conductor shall not be higher than 70oC.

2. Conductor maximum short circuit (not more than 5 seconds) temperature shall not be higher than 160°C.

3. The power cable is not limited by drop in level when being laid, and the ambient temperature shall not be lower than 0°C.

If so, the cable should be preheated.

4. Perfect chemical stability, resistant against acids, alkalis, grease and organic solvents, and flame.

5. Light weight, perfect bending properties, installed and maintained easily and conveniently.
