Leading manufacturer of Steel Wire Armoured Cables – SWA
Steel wire armoured cables – also referred to as SWA cables – are generally multicore cables with a layer of steel wires twisted around the internal construction. Armoured cables have this extra protective layer to provide mechanical protection. The cable armour in this case provides protection for the cable from damage. Steel wire armoured cables are usually power cables that will be used within applications where the cable will be buried underground. The cable armour protects it from damage such as from drilling, digging, etc., ensuring that the circuit integrity is retained and that the threat to life is minimised.
Armoured cable can be used for a vast array of applications, but are commonly associated with ‘underground’ power applications, such as within power distribution networks, sewers and underground transport networks. If you’re working in harsh environments where the cable may be exposed to physical damage, armoured cables will be an ideal choice for your workplace. However, when deployed in public places, fire resistant cable variants must be used to ensure that any hazard from smoke and noxious gases in a fire situation is avoided.
There are many reasons why armoured cables are the best choice, including:
Mechanical protection
The cable armour protects against impacts, rodents, or accidental damage. If you’re working in conditions that are highly volatile or harsh, an armored cable will be the best choice for you. They are most commonly used underground, and are usually found in underground transport and power distribution.
Durability:
Armoured cables are designed for particularly tough conditions, including outdoor and underground settings and also in industrial locations. The cable armour protects the inner workings of the cable, meaning they can withstand a lot. Our range of cables includes everything from 2.55mm to 10mm armoured cables, so there will always be the right fit for your business.
Electrical safety
The cable armour protects the cable, and reduces the risk of short circuits due to cable damage. If you’re working in environments that require high voltage electricity, and need to withstand any damage, armoured cables are essential.
Armoured cables are generally very stiff and would not be considered flexible, and are therefore not suited to applications when flexibility is a requirement. Steel wire armoured cables are usually rigid to be able to withstand the damage, but if you need flexibility, a galvanised steel wire braid would provide a similar level of protection but also provide the pliability needed.
One product multiple uses
We have the capability to further enhance pre-existing cables with the addition of an armoured layer and further outer jacket. This service is quite popular with cable distributors offering them the ability to only hold one type of product in stock at one time, reducing stockholding whilst giving the ability to quickly convert an unarmoured product to an armoured one as quickly as possible.
Armoured cables have a lot of uses, in a lot of different industries and settings. In general, these cables tend to be used to provide power supply to sheds, garages, or outbuildings. They can also be used in outdoor lighting circuits, industrial or commercial installations, and sub-main feeds in buildings. The cable armour makes these cables perfect for using outdoors and underground, as they are difficult to damage.

Frequently asked questions about armoured cables
What can I run on 2.5 mm armoured cable?
A 2.5mm armoured cable is generally used for underground projects such as garden lighting, outdoor shed sockets, factory lighting, security gates, and other outdoor lighting due to their smaller size. However, if you need larger armoured cables for big projects and industrial applications, our range of cables reaches 6mm-10mm, so you will be able to find the best cable for your use. If you have any questions about which cables you need, you can call us on 01204 658784.
What is the lifespan of armoured cable?
Armoured cables are designed for long-term use, as they are highly durable and are often used in specialist industrial applications. With proper conditions and maintenance, armoured cables can last between 20-30 years. The heavy cable armour allows them to withstand a lot of damage, and continue to work effectively. Their durability makes them perfect for settings such as power distribution and underground transport.
What are the disadvantages of armoured cable?
There are many advantages to armoured cables, including their durability, mechanical protection, and electrical safety. However, because of the cable armour, they are often not as flexible which can mean they are not suitable for some uses. Steel wire armoured cables are rigid because they need to be durable, however, a galvanised steel wire braid would provide a similar level of protection but also provide the flexibility needed.
Where can armored cable not be used?
Armoured cables are useful in many settings, because of their high level of durability and electrical safety. However, it’s important to use them in the right places as there are certain settings where armoured cables would not be appropriate. In highly flexible applications, armoured cables are stiff and wouldn’t be the best choice. They are heavy, so it can’t be temporary cabling. They should also not be used in certain explosive areas without specific additional certifications, or where corrosion risk is extremely high. However, if you have any questions about our armoured cable, you can get in touch with us and our sales team will be happy to assist you.
Is armoured cable rat proof?
One of the many positive aspects of armoured cable is that it is very difficult to damage, including by rats and other animals, so they are the perfect choice for a lot of different settings.
