FAQ

1.What are the typical applications for 64/110kV cables?

  • Substation interconnections (GIS to transformer bays)
  • Underground transmission networks in urban areas
  • Power distribution for industrial complexes requiring high-voltage input

2.How does corrugated steel sheath (CWS) enhance cable performance?

  • Provides mechanical protection against rodent damage
  • Improves water resistance in underground or submarine installations
  • Maintains structural integrity under thermal expansion (operating temp: -25°C to +90°C)

3. What bending radius should be maintained during installation?

  • Minimum bending radius: 20 times outer diameter (for single-core cables)
  • For 2500mm² cable (OD≈120mm): ≥2.4m to avoid conductor deformation

4. How are 64/110kV cables terminated?

  • GIS terminals (gas-insulated switchgear) for substations
  • Outdoor porcelain or composite terminals with stress cones
  • Prefabricated joints for field splicing (waterproof design)

5.How does XLPE insulation compare to oil-paper insulation?

  • Higher dielectric strength (≥200kV/mm vs 150kV/mm)
  • No oil maintenance required
  • Lighter weight (30% reduction for same voltage rating)

6. What are the storage requirements for 64/110kV cables?

  • Reels stored upright with anti-roll blocks
  • Temperature: -15°C to +40°C
  • Shelf life: ≤12 months (UV-protected wrapping needed for outdoor storage)

7.How to calculate the ampacity of 2500mm² 64/110kV cable?

  • In air: ≈1200A (ambient 30°C, soil thermal resistivity 1.2K·m/W)
  • In duct: ≈800A (grouped with 3 other cables)
  • Reference: IEC 60287-1-1 with derating for CWS sheath
