AWA cable plays a crucial role in powering modern industrial infrastructure. As industries scale and projects become more complex, the demand for reliable, lightweight, and cost-effective cabling solutions continues to grow. That’s where aluminium wire armoured cables come in.
In this article, we’ll walk through the benefits of using an AWA cable, where they’re most effective, and how they compare to other cable types such as SWA. If you’re involved in specifying or installing electrical cables in demanding environments, this guide will give you the clarity you need.

What is AWA Cable?
AWA cable is an aluminium wire armoured cable designed for mechanical protection in single-core cable installations. The aluminium armouring offers strength and resilience without the magnetic properties of steel, which makes these cables ideal for specific AC power applications.
These cables typically include a conductor (often copper or aluminium), XLPE insulation, and a robust aluminium wire armouring layer under a protective outer sheath. The result is a cable that’s tough enough for harsh environments but remains non-magnetic, which is an important characteristic for avoiding eddy current losses in single-core AC systems.
AWA Cable Applications in Industry
AWA cable applications span several sectors, particularly where single-core power distribution is required:
1. Power Stations and Substations
AWA cable is commonly installed in high-voltage and medium-voltage single-core applications at substations. Their non-magnetic armour eliminates issues caused by circulating currents.
2. Industrial Manufacturing Facilities
Heavy machinery, automation systems, and industrial control gear benefit from the mechanical protection and electromagnetic performance of AWA cabling.
3. Energy Infrastructure
In renewable energy projects, such as solar farms and wind turbine installations, aluminium wire armoured cables offer a balance between weight, durability, and cost.
4. Commercial Construction
AWA is often used in high-rise buildings or large commercial sites where single-core cables carry high current through cable trays and trunking.
AWA vs SWA: What’s the Difference?
The AWA vs SWA debate comes up often when choosing armoured cables. Here’s a quick breakdown:
| Feature | AWA Cable | SWA Cable |
| Armour Material | Aluminium Wire | Steel Wire |
| Magnetic? | Non-magnetic | Magnetic |
| Used For | Single-core cables | Multi-core cables |
| Weight | Lighter | Heavier |
| Eddy Current Loss | None | May occur in single-core systems |
In short, AWA cable is best for single-core AC installations due to their non-magnetic properties. SWA (Steel Wire Armoured) cables, on the other hand, are used for multi-core systems where mechanical protection is needed, and magnetic interference isn’t a concern.
Key Benefits of AWA Cables
Here’s why AWA cables are a top choice in industrial projects:
1. Non-Magnetic Armour
Prevents unwanted eddy current losses in single-core installations, improving energy efficiency and cable longevity.
2. Lightweight and Easy to Handle
Compared to steel-armoured options, aluminium wire armoured cable is easier to install, especially over long distances or in overhead applications.
3. Excellent Mechanical Protection
The armouring offers strong resistance to impact, crushing, and physical stress, which is essential in demanding environments.
4. Corrosion Resistance
Aluminium’s natural resistance to corrosion adds another layer of durability in outdoor or underground installs.
5. Cost-Effective
Aluminium is generally cheaper than steel, making AWA cables a budget-friendly choice for large-scale infrastructure.
Choosing the Right Aluminium Wire Armoured Cable
Selecting the correct aluminium wire armoured cable depends on several project-specific factors:
- Voltage rating: Ensure the cable’s rated for your operating voltage (often 11kV or 33kV for industrial uses).
- Installation environment: Consider moisture, mechanical stress, and potential chemical exposure.
- Cable size and current rating: Match the conductor size to the system’s current demands.
- Regulatory standards: Confirm compliance with IEC and BS specifications where required.
Always consult with a certified installer or supplier to ensure you’re making the right choice for safety and performance.
Final Thoughts
AWA cables have earned their place as a go-to solution in industrial environments, especially where non-magnetic, mechanically protected single-core cables are essential. Their versatility, cost-effectiveness, and efficiency make them ideal for powering critical infrastructure.Need help choosing the right aluminium wire armoured cable for your project?
