4x300mm2 SWA Armoured Cable Steel Wire Armour Direct Burial Power Cable 0.6/1kV IEC 60502-1

Product Overview

This 4x300mm2 SWA armoured power cable features a galvanized Steel Wire Armour (SWA) layer that delivers exceptional mechanical protection for the most demanding low voltage power installations. Rated at 0.6/1 kV and manufactured to IEC 60502-1 and BS 5467, the cable is designed to withstand high pulling tensions, crushing forces, and earth pressure during direct burial, outdoor trench, and indoor installation.

With high-grade stranded aluminium conductors and XLPE insulation, this armoured cable combines rugged physical protection with excellent electrical performance. The SWA layer eliminates the need for additional protective conduits in most direct burial applications, significantly reducing installed system cost.

Key Product Advantages

• Heavy-Duty SWA Mechanical Protection: The galvanized steel wire armour layer ensures the cable withstands high pulling tensions and resists crushing forces, rodent attacks, and mechanical damage in harsh environments.
• Direct Burial Ready: The SWA layer provides the necessary mechanical shield against earth pressure, allowing direct burial without extra conduits except where local regulations require ducting under roads or high-traffic areas.
• Cost-Effective Aluminium Conductor: A lighter and significantly more budget-friendly alternative to copper for long-distance high-current transmission without compromising electrical performance.

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: Is this 4x300mm2 SWA 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.

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

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: What is the minimum bending radius of this armoured cable?

The minimum bending radius during installation is 12 times the overall diameter (12x OD). Bending the cable beyond this limit may damage the galvanized steel wire armour layer or strain the internal XLPE insulation cores.
