11kV ATA Aluminum Wire Armored Electrical Cable Single Core AL/XLPE/AWA/CWS/PVC-FR-LS Cable

APPLICATION

11kV ATA Aluminum Wire Armored Electrical Cable (Single Core AL/XLPE/AWA/CWS/PVC-FR-LS) is a specialized medium-voltage power cable designed for industrial and urban power distribution systems. Its key applications include:

• Underground Power Transmission‌.
• Industrial Facilities‌
• Renewable Energy Projects‌
• Critical Infrastructure‌

CONSTRUCTION

• Conductor: Plain annealed copper or aluminium wire.
• Conductor Screen: Extruded layer of semi-conducting cross-linkable compound.
• Insulation: XLPE 
• Insulaton Screen: Extruded layer of semi-conducting cross-linkable compound is applied over the insulation.
• Metallic Layer: copper tapes or a concentric layer of copper wires or a combination of tapes and wires.
• Separation Sheath (for armoured cable): PVC, PE or LSZH.
• Armour (for armoured cable): round aluminium wire.
• Over Sheath: PVC or MDPE. LSZH can be offered as an option.

CHARACTERISTIC 

• Voltage Rating Uo/U: 6.35/11kV 
• Maximum operating temperature of conductor:+90℃
• Operating ambient temperature: -15℃~+45℃
• Cable laying temperature:Not less than 0℃(When the ambient temperature is below 0℃, the cable should be preheated.) 
• Minimum Bending Radius: 12D (D is the actual outer diameter of the cable)

FAQ

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
