Medium Voltage XLPE Insulated Power Cable 8.7/15kV Corrasion Resistance
Powering Industrial Resilience: Shenghua’s 8.7/15kV XLPE Cables for Demanding Environments
In industries where power reliability and infrastructure longevity are mission-critical, Shanghai Shenghua Cable Group—ranked among China’s top cable manufacturers with exports to 30+ countries—delivers engineered excellence with its 8.7/15kV XLPE Insulated Power Cables. Designed for medium-voltage applications, these cables combine advanced corrosion resistance, unmatched thermal stability, and compliance with global standards, making them the backbone of robust power distribution networks .
Engineering Superiority: Multi-Layer Defense System
Shenghua’s cables leverage precision engineering to conquer harsh environments:
- Triple Shielding:
- Conductor Screen: Semi-conductive layer to eliminate partial discharges
- Insulation: XLPE rated for 90°C continuous operation (130°C emergency, 250°C short-circuit), ensuring dielectric integrity during surges
- Insulation Screen: Semi-conductive layer + copper tape shield for uniform voltage distribution and EMI protection
- Corrosion Resistance: PVC/FR-PVC sheath (ST2 to IEC 60502) fortified against chemicals, moisture, and abrasion—ideal for direct burial or industrial zones
- Mechanical Durability: Minimal bending radius (15× cable OD for multi-core) enables installation in congested trenches or ducts
This design extends service life beyond 50 years in petrochemical plants, coastal sites, and mining operations .
Certifications and Global Compliance
Shenghua adheres to stringent international benchmarks:
- Standards: IEC 60502-2, IEC 60228, GB/T 12706, with optional BS/DIN/ICEA compliance
- Certifications: CE, RoHS, KEMA, ISO 9001/14001, and China’s CCC
- Rigorous Testing: AC withstand voltage (30.5kV/5min) and partial discharge (<10pC) ensure zero defects
Applications: Where Reliability Meets Versatility
Shenghua’s cables excel in high-stakes environments:
- Energy Grids: Underground distribution networks with direct burial capability
- Industrial Complexes: Chemical plants requiring corrosion resistance (FR-PVC sheath) and 485A load capacity (3×400mm²)
- Renewable Projects: Wind/solar farms leveraging XLPE’s 90°C thermal stability for uninterrupted transmission .
Critical Note: Multi-core configurations avoid eddy currents in magnetic ducts—armored variants (e.g., YJV22) recommended for high-pressure zones .
