Key Product Advantages

• Cost-Effective Aluminium Conductor: Offers a lighter and significantly more budget-friendly alternative to copper conductors for long-distance high-current transmission without compromising electrical performance.
• Heavy-Duty SWA Mechanical Protection: The Steel Wire Armour layer ensures the cable withstands high pulling tensions and resists mechanical damage, allowing for direct burial in harsh soil conditions.
• Excellent Thermal Properties: The XLPE insulation allows the cable to operate continuously at 90°C, increasing the current-carrying capacity and lifespan under overload conditions.

Applications

• Underground power supply networks for industrial factories and power stations.
• Main power feeders in commercial building complexes and infrastructure projects.
• Direct burial, outdoor cable trenches, or indoor cable trays where mechanical protection is required.

Quality Control & Factory Capability

• Certifications: ISO9001, CE, RoHS, and type test reports from independent third-party laboratories.
• 100% Routine Testing: Every batch undergoes Spark Test, Conductor Resistance Test, and High Voltage Test before delivery.
• OEM & Customization: Custom outer sheath colors, custom marking/printing, and custom packing lengths (e.g., 500m/drum or 1000m/drum) are available.

Frequently Asked Questions (FAQ)

Q: What is the current carrying capacity of a 4x300mm2 aluminium SWA cable?

The current rating depends on the installation environment. When buried directly in the ground at a standard soil temperature of 20°C, it typically carries approximately 410A to 445A for XLPE insulated versions. For precise calculations based on your specific laying depth and thermal resistivity, please contact our engineering team.

Q: Can this 4x300mm2 aluminium cable replace a copper cable?

Yes. To achieve the same current carrying capacity as a copper cable, you generally need to select an aluminium cable that is one or two sizes larger in cross-sectional area due to the difference in conductivity. Using 4x300mm2 aluminium drastically cuts down the material purchasing budget for large infrastructure projects.

Q: Is this cable suitable for direct burial without extra conduits?

Yes, the Steel Wire Armour (SWA) provides the necessary mechanical shield against crushing forces and earth pressure. It can be buried directly in the ground without additional protective piping, except when crossing public roads or high-traffic areas where ducts are regulatory.
