Premium XLPE Insulated Power Cables for 21/35(36)kV Applications
Shenghua's low-voltage XLPE insulated power cables (21/35(36)kV) combine cutting-edge engineering with extreme abrasion resistance, delivering reliable power transmission for industrial grids, renewable energy farms, and urban infrastructure. Trusted across 60+ countries, our cables ensure safety, efficiency, and compliance with global standards.
Market-Leading Features
- Triple-Layer Defense System: Compact stranded aluminum conductor (IEC 60228 Class 2) reduces weight by 60% versus copper while lowering installation costs.
- Advanced Insulation: XLPE (cross-linked polyethylene) rated for 90°C continuous operation, 130°C emergencies, and 250°C short circuits (≤5 sec) - outperforming PVC in thermal aging and chemical resistance.
- Protective Sheath: Abrasion-resistant PVC or FR-PVC (IEC 60502 ST2) provides UV protection, flame retardancy, and mechanical durability for indoor/outdoor applications.
Engineered for Performance & Safety
- Superior Abrasion Resistance: Reinforced sheath withstands friction from direct burial, duct pulling, and industrial wear, significantly extending cable lifespan.
- Enhanced Fire Safety: FR-PVC sheath inhibits flame spread and reduces toxic fumes (compliant with IEC 60332/60754), critical for tunnels and crowded spaces.
Global Compliance & Certifications
- International Standards: IEC 60502-1, GB/T 12706, with custom approvals for BS/DIN/ICEA
- Certifications: CE, RoHS, KEMA, with LSOH (Low Smoke Zero Halogen) options available

Efficiency Highlights:
- Ultra-low resistance (e.g., 0.0778Ω/km for 4×400mm²) reduces energy loss by 10-15%
- Minimal bending radius (15× OD for multi-core) simplifies installation in tight spaces
Critical Applications
- Industrial Zones: Withstands oil, chemicals, and mechanical stress; 305A soil current (4×185mm²) powers heavy machinery
- Renewable Energy Farms: Aluminum conductors resist soil corrosion; XLPE insulation endures -40°C to 130°C
- Urban Underground Grids: FR-PVC sheath prevents abrasion during direct burial; zero toxic fumes enhance public safety
Manufacturing Excellence
- Scale & Quality: 5000+ employees, ISO 9001/14001 certifications, and 15,000 km/month capacity ensure batch consistency
- Global Logistics: Wooden drum packaging for damage-free shipping; MOQ 200 meters, 30% deposit pre-production
- Custom Solutions: Tailored configurations for extreme abrasion/chemical exposure environments
