Q: What is the key feature of this cable's armor layer?
A: The ATA (Aluminum Tape Armor) provides mechanical protection against rodent damage and soil pressure while maintaining flexibility for underground installation
Q: Why is XLPE insulation preferred for 11kV cables?
A: XLPE (Cross-Linked Polyethylene) offers superior thermal stability (up to 90°C operating temperature) and dielectric strength compared to PVC, making it ideal for medium-voltage applications
Q: What does PVC-FR-LS in the sheath specification mean?
A: It denotes a Flame Retardant (FR) and Low Smoke (LS) Polyvinyl Chloride sheath, reducing toxic emissions during fires and enhancing safety in tunnels or buildings
Q: Where is this cable typically installed?
Designed for Cable Wiring System (CWS) in underground networks, industrial plants, and renewable energy projects due to its corrosion-resistant armor and moisture-blocking properties
Q: What conductor material is used and why?
A: Aluminum (AL) conductors are chosen for cost-effectiveness and lightweight properties, though copper options may be available for higher conductivity requirements
Q: Does this cable comply with international standards?
A: Yes, it meets IEC 60502-2 for power cables and IEC 60332-3-24 for flame propagation resistance, ensuring global acceptance
Q: Can it be used in coastal environments?
A: Absolutely. The ATA armor resists saltwater corrosion, and XLPE insulation prevents moisture ingress, making it suitable for coastal infrastructure
Q: How does the low-smoke sheath benefit emergency scenarios?
A: During fires, it minimizes visibility-obstructing smoke and toxic gas release, aiding evacuation and firefighting efforts in critical facilities
Q: Is this cable suitable for aerial installations?
A: No. While it’s armored for underground use, aerial applications require specialized designs like steel wire armor (SWA) or messenger wire
