Low Voltage XLPE Insulated Power Cable 21/35(36)Kv Abrasion Resistance
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:
- Thermal Stability: Withstands temperatures up to 90°C (continuous), 130°C (emergency), and 250°C (5-second short circuit)
- Abrasion Resistance: Reinforced PVC or FR-PVC sheath (ST2 to IEC 60502) protects against mechanical wear, chemicals, and environmental stress
- 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
