Manufacturing & Projects
Frequently Asked Questions
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
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)
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
How are 64/110kV cables terminated?
- GIS terminals (gas-insulated switchgear) for substations
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)
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)
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
