Shanghai Shenghua Power Group: Revolutionizing Safety with LSZH Copper Cables for Critical Infrastructure​​

​​Shanghai Shenghua Cable (Group) Co., Ltd.​​—a ​​Top 500 Chinese manufacturer​​ with ​​20+ years of expertise​​—sets a new benchmark in fire safety with its ​​450/750V LSZH Copper Building Wire​​. Engineered for high-risk environments like subways, hospitals, and data centers, this IEC-certified solution combines zero-halogen innovation, extreme thermal resilience, and global compliance to protect lives and assets worldwide

​​1. Advanced Engineering for Life-Saving Performance​​

• ​​Zero-Halogen Innovation​​:
  • ​​LSZH Insulation​​: Eliminates toxic fumes (HCl, HBr) during fires, reducing smoke opacity to ​​>60% light transmittance​​ (vs. <20% for PVC) and limiting acid gas emissions to ​​<0.2% halogen content​​
    
    
  • ​​Corrosion Prevention​​: PH value of combustion gases maintains ​​≥4.3​​ (weak acidity), protecting sensitive equipment in control panels
    
    
• ​​Thermal Resilience​​:
  • ​​90°C Continuous Operation​​: Surpasses standard PVC (70°C) in high-heat zones like motor starters
    
    
  • ​​150°C Short-Circuit Survival​​ (5s): Prevents meltdowns during electrical faults
    
    
• ​​Flexible Conductors​​:
  • ​​Class 5 Stranded Copper​​: 360° bendability (e.g., ​​4× OD radius​​ for ≤35mm² cables) for tight conduits in switchgear
    
    

​​2. Certified Global Compliance​​

• ​​Standards​​: IEC 60227, GB/T 5023 (BV-90), with optional BS/DIN/ICEA certification
  
  
• ​​Safety Certifications​​: CE, RoHS, CCC, UL, REACH—ensuring EU/UKCA/ANSI market access
  
  
• ​​Fire Safety​​: Exceeds IEC 60332 flame tests and IEC 60754-1/2 gas emission limits
  
  

​​3. Technical Superiority Across Applications​​

​​Key Specifications​​:

​​Applications​​:

• ​​Healthcare & Schools​​: LSZH sheath reduces smoke toxicity in evacuation-critical sites (e.g., 80% lower CO vs. PVC)
  
  
• ​​Data Centers​​: Halogen-free materials prevent server corrosion during fires
  
  
• ​​Industrial Control Panels​​: Stranded conductors (Class 5) resist fatigue in vibrating machinery
  
  

​​4. Why Global Partners Trust Shenghua?​​

• ​​Manufacturing Excellence​​:
  • ​​Zero-Defect Policy​​: 100% IACS copper purity (99.99%) minimizes resistance to ​​0.0221Ω/km​​ (240mm²), cutting energy loss by 30%
    
    
  • ​​Scalable Production​​: ​​5,000 km/month output​​ with ​​10-day global delivery​​
    
    
• ​​Customization & Service​​:
  • ​​OEM Flexibility​​: Supports solid/stranded conductors, 12+ colors, and CCA alternatives
    
    
  • ​​2-Year Warranty​​: PICC-backed coverage + ​​24/7 support​​ (72-hour global response)
    
    
    .
• ​​Sustainability​​:
  • ​​Recyclable Copper​​: 95% reuse rate vs. 65% for aluminum, aligning with LEED green building goals
