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 .
Technical Specifications: Performance Quantified
Key data for Shenghua’s 3-core copper cables (8.7/15kV):
| Conductor (mm²) | Insulation Thickness (mm) | Max. DC Resistance (Ω/km) | Current Rating (A) |
|---|
| 3 × 120 | 4.5 | 0.253 | 235 (Air/Soil) |
| 3 × 240 | 4.5 | 0.125 | 370 (Air) / 345 (Soil) |
| 3 × 400 | 4.5 | 0.078 | 485 (Air) / 440 (Soil) |
Higher cross-sections (e.g., 400mm²) support substations or heavy
industries demanding 485A loads .
