What Is an Armoured Power Cable?
An armoured power cable is an electrical cable designed with a built-in layer of protection. This layer usually consists of steel or aluminium wiring that shields the internal components from impact, stress, and environmental wear. The result is a highly durable cable suited for demanding conditions without compromising electrical performance.
These cables are often installed in areas where regular PVC cables would be too fragile, such as underground trenches, outdoor fixtures, or high-traffic zones.
How Armoured Power Cables Work
Understanding how armoured power cables work starts with recognising their added toughness. While the conductors and insulation inside are similar to standard cables, it’s the outer metallic armour that makes all the difference. This armour protects the cable from sharp objects, crushing forces, or vibration.
It also acts as an added safety feature, especially in hazardous environments, helping prevent accidental damage that could lead to power failure or danger.
A Closer Look at Armoured Cable Structure
A typical armoured cable structure includes multiple engineered layers:
- Conductors – Copper or aluminium wires that carry current.
- Insulation – Protects against electrical leakage.
- Bedding – Adds cushioning between the insulation and armour.
- Armour Layer – Steel wire or aluminium wire for mechanical protection.
- Outer Sheath – Guards against moisture, chemicals, and UV rays.
Each layer works together to keep the cable operational and safe in rugged installations.
Key Applications for Armoured Power Cables
You’ll find armoured power cables used across many sectors where mechanical damage is a risk. Here are some popular applications:
- Underground wiring
- Industrial equipment connections
- Outdoor lighting
- Solar and wind energy systems
- Rail and transport infrastructure
These cables are chosen for long-term durability and performance where failure is not an option.
Choosing the Right Type of Armoured Power Cable
Not all armoured cables are built the same. Selecting the right one depends on:
- Voltage requirements
- Weight and flexibility needs
- Environmental exposure
- Industry regulations
Steel wire armoured (SWA) cables are ideal for general low-voltage work, while aluminium wire armoured (AWA) cables are lighter and easier to handle.

Installation Considerations for Armoured Power Cables
Even though armoured power cables are made for tough conditions, a proper install still matters. Keep these points in mind:
- Avoid sharp bends or tension during pulls
- Use approved glands and terminations
- Bury underground cables at recommended depths
- Test before energizing
Treating the cable right during install helps avoid performance issues later.
Final Thoughts
When you understand how armoured cables work, you’re better equipped to deliver safe, reliable, and long-lasting installations. They’re built for strength and used in the kind of places where reliability matters most.
