What is the Difference Between AWA and SWA Cable?

When it comes to armoured cables, AWA (Aluminum Wire Armoured) and SWA (Steel Wire Armoured) cables are two of the most commonly used types in power distribution and industrial electrical installations. Although both are designed to provide mechanical protection and durability, they serve slightly different purposes and are suitable for different environments.

As a professional cable manufacturer, Honrey Cable offers both AWA and SWA cables that meet international standards and are trusted by engineers and contractors worldwide. In this article, we break down the key differences between AWA and SWA cables to help you choose the right one for your application.

What is SWA Cable?

Steel Wire Armoured (SWA) cable is a robust, heavy-duty power cable typically used in underground systems, cable ducts, and power networks. It consists of:

Copper conductor
XLPE or PVC insulation
Steel wire armour layer
PVC outer sheath

The steel wire armour provides excellent protection against mechanical stress, making SWA cables ideal for outdoor and underground installations where they may be exposed to physical impact.

Typical applications of SWA cable:

Power distribution in industrial and commercial buildings
Underground power networks
Outdoor installations and heavy-duty environments

What is AWA Cable?

Aluminum Wire Armoured (AWA) cable is similar in construction to SWA but uses aluminum wires for the armouring layer instead of steel. AWA cables are typically used for single-core power cables because aluminum is non-magnetic, which helps prevent eddy currents and overheating in alternating current (AC) systems.

Structure of AWA cable:

Copper conductor (or aluminum)
XLPE or PVC insulation
Aluminum wire armour (non-magnetic)
PVC outer sheath

Typical applications of AWA cable:

Single-core AC power cables
Power stations and substations
Electrical panels and switchgear systems

Key Differences Between AWA and SWA Cable

Feature	AWA Cable	SWA Cable
Armour Material	Aluminum wire	Steel wire
Magnetic Properties	Non-magnetic (safe for single-core AC)	Magnetic (not ideal for single-core AC)
Usage	Single-core cables	Multi-core cables
Mechanical Strength	Moderate	High
Weight	Lighter	Heavier
Cost	Generally more economical for single-core systems	Slightly higher due to steel material

Which One Should You Choose?

Choose AWA cable for single-core AC power systems where magnetic interference must be avoided.

Choose SWA cable for multi-core systems or installations requiring high mechanical protection.
