Powering Resilience: Shenghua’s 21/35kV XLPE Cables for Demanding Electrical Networks

In an era where energy efficiency and infrastructure durability are paramount, ​​Shanghai Shenghua Cable Group​​ delivers cutting-edge solutions with its ​​21/35kV XLPE Insulated Power Cables​​. Engineered for low-voltage applications, these cables combine superior electrical performance, exceptional abrasion resistance, and compliance with global standards—making them the ideal choice for modern power transmission networks.

​​Unmatched Performance in Extreme Conditions​​

Shenghua’s cables excel under rigorous operational demands:

1. ​​Thermal Stability​​: Withstands temperatures up to ​​90°C (continuous)​​, ​​130°C (emergency)​​, and ​​250°C (5-second short circuit)​​
   
   

   
   
2. ​​Abrasion Resistance​​: Reinforced PVC or FR-PVC sheath (ST2 to IEC 60502) protects against mechanical wear, chemicals, and environmental stress
   
   
3. ​​Flexible Installation​​: Minimal bending radius (​​15× cable OD for multi-core​​) allows deployment in confined spaces like tunnels or ducts
   
   

These properties ensure longevity in harsh environments—from industrial plants to coastal areas with high salinity or chemical exposure.

​​Engineering Excellence: Materials and Construction​​

Every Shenghua XLPE cable is precision-engineered:

• ​​Conductor​​: Compact stranded aluminum (Class 2 per IEC 60228), reducing weight and cost while maintaining conductivity
  
  
• ​​Insulation​​: Cross-linked polyethylene (XLPE) offers low dielectric loss, high insulation resistance, and resistance to electrochemical degradation
  
  
• ​​Sheath​​: Black PVC/FR-PVC provides UV resistance and flame retardancy (meeting GB/T 18380-3 for ZR variants)
  
  

This design minimizes energy loss by ​​30%​​ compared to traditional PVC cables and extends service life beyond ​​50 years​​

Certifications and Global Compliance​​

Shenghua adheres to stringent international standards:

• ​​Core Certifications​​: IEC 60502-1, IEC 60228, GB/T 12706 (China), with optional BS/DIN/ICEA compliance
  
  
• ​​Quality Assurance​​: CE, RoHS, KEMA, and CCC certifications guarantee safety and eco-sustainability
  
  
• ​​Rigorous Testing​​: AC withstand voltage (3.5kV/5min) and conductor resistance tests ensure zero defects
