Shenghua XLPE Insulated Power Cables: Revolutionizing 21/35(36)kV Power Transmission with Unmatched Durability
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.
Why Shenghua’s XLPE Cables Lead the Market
-
Triple-Layer Defense for Extreme Environments
- Conductor: Compact stranded aluminum (IEC 60228 Class 2), reducing weight by 60% vs. copper and slashing installation costs
- 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
- Sheath: Abrasion-resistant PVC or FR-PVC (IEC 60502 ST2), providing UV protection, flame retardancy, and mechanical durability for indoor/outdoor use
-
Engineered for Abrasion Resistance & Safety
- Abrasion Defense: Reinforced sheath withstands friction from direct burial, duct pulling, and industrial wear, extending cable lifespan
- Fire Safety: FR-PVC sheath inhibits flame spread and toxic fumes (compatible with IEC 60332/60754), critical for tunnels and crowded spaces
-
Global Compliance & Certifications
- Standards: IEC 60502-1, GB/T 12706, and custom approvals for BS/DIN/ICEA
- Certifications: CE, RoHS, KEMA, with LSOH (Low Smoke Zero Halogen) options upon request

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: Where Shenghua Excels
- 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
Shenghua’s Manufacturing Edge
- 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
- Customization: Tailored solutions for extreme abrasion/chemical exposure (e.g.
