FAQs of 10kV Cable
What is the rated voltage of XWA 35kV cable, and what does U0/U 26/35kV mean?
The rated voltage of XWA 35kV cable is U0/U 26/35kV, in full compliance with IEC 60502-2 and GB/T 11017 المعايير.
- U0 (26كيلو فولت): The maximum voltage that the cable insulation can withstand between the conductor and the earth (or metallic screen) during long-term operation.
- U (35كيلو فولت): The maximum voltage between any two conductors of the cable during long-term operation.This voltage grade is specifically designed for 35kV high-voltage power transmission and distribution networks, ensuring safe and stable operation under high electric field stress.
What are the key installation requirements for XWA 35kV cable, especially for direct burial?
XWA 35kV cable supports direct burial, قناة, tunnel, and overhead installations, with these critical requirements:
- Minimum bending radius: ≥ 20D (armored) or ≥ 15D (unarmored), where D is the cable outer diameter (stricter than 10kV cables to protect the thicker insulation).
- Burial depth: ≥ 1.0 meters (1.2 meters in traffic areas) to avoid mechanical damage and external stress.
- Protection layer: Sand cushion (≥ 100mm) and concrete/brick cover must be laid above the cable to prevent crushing.
- Avoidance: Keep away from chemical corrosion sources, high-temperature pipelines, and sharp objects to extend service life.
What is the design service life of XWA 35kV cable, and what factors affect it most?
Under rated operating conditions (compliant with IEC standards), XWA 35kV cable has a design service life of up to 40 سنين.Key factors affecting its lifespan:
- Operating temperature: Long-term operation above 90°C will accelerate XLPE insulation aging.
- Partial discharge: Poor manufacturing or installation can cause partial discharges, which gradually degrade the insulation.
- Environmental stress: UV radiation, التآكل الكيميائي, and soil moisture will reduce insulation performance over time.
- Overload faults: Frequent short-circuit or overload events will damage the insulation and metallic screen.
Can XWA 35kV cable be customized for special project needs?
- موصل: High-purity copper or aluminum, cross-sections from 50mm² to 800mm².
- العزل & sheath: XLPE/HEPR insulation, with PVC/PE/LSZH (halogen-free) sheath options.
- التدريع: سوا (steel wire armor) or STA (steel tape armor) for enhanced mechanical protection.
- Special features: Water-blocking layers, fire-resistant structures, or custom lengths (supplied on steel drums for long lengths).
What other medium voltage cables do you provide?
