Chapter 2: What are the Armoured Cables?
Armoured cable is a name that is given explicitly to some electrical wire which is manufactured with a shell of aluminium or steel.
This shell or armour lies beneath the cable sheath. It is for the protection of the driver and to insulate the coatings.
In other words, Armoured cable is a type of cable which is covered with a metal casing.
These cables are covered with metal armour protection from outside. So, it can be protected automatically from any damage.
These cables are consistent with outdoor connections.
The metal armour of the shell protects the cable from the damage of scratches, theft, ripping, and decomposition.
For electrical and cable applications, a slew of wires is available in all types. As a professional electrician, it becomes easy to choose what app is for what product.
Mostly, armoured cables are used in mains supplies and underground drains or subways.
An assortment of armoured cables is available including 2 to 7 core wires. Underground armoured cable has various features.
They are notable for the differing number of conductors within them covered with insulation, armoured PVC and other sturdy material. They also have a sheath for wrapping.
Chapter 3: What are the features of the Armoured Cables?
Armoured cables are flexible, durable and have the capacity of carrying high current flow with small bending range. They are resistant to flame, heat, and oil.
Besides, they have properties of low conductor resistance and are remarkably mechanical
Chapter 4: What varieties are available in Armoured Cables?

What are SWA Cables?
SWA is supporting and power control cable. It is specially made to use in electricity supplies.
It has different protected electrical links.it includes 33 kV cable and 11 kV cable. It can be found in control grids and drain systems and also in cable channels.
Steel Wire Armoured (SWA) cable is a power controller and supplier cable that is specially shaped to use in the main supplies of electricity.
It can be utilized for underground and subway systems; cable networks, power networks, indoor and outdoor applications and also cable ducting.
The SWA cable is also subjected to the main cable, power cable, armoured cable and booklet-armoured cable. It is a copper wiring perfect conductor, for instance, with the reach of 2 core, three core, and five core SWA Cables.
Mechanically protected design of SWA Cables makes it preferred for external use. Its durable steel shielding minimizes the risks of shrinking and other external harms.
Bulk size of SWA cables makes them quite difficult to turn or twist; which is why they are best suited to subway cabling or outside walls implantation.
SWA cable provides mechanical protection. That’s why this cable is frequently considered for external usage.
The armoured cable is taken as less risk of getting damaged. For the protection of wire, steel is used, which makes it robust.
SWA cable is mostly used for underground cabling because these cables are much more substantial. They cannot bend so quickly that’s why these are used for outdoor wiring.
Different names are used for steel wire Armoured cables Mains Cable, Booklet Armoured Cable, and Control Cable.
The term power cable applies to several links which include 6491X, NYY-J, 6381Y and NYCY cable.
Use of SWA as earthing
In the electrical installation, the industry has controversy about using SWA for giving grounding or earthing to the tool which is supplied by cable.
This function is also known as the circuit protective conductor in technical terms.
An extra core inside the cable is known as CPC. For example, for line and armouring and the neutral, three-core cable is used instead of two core cable as CPC.
Along with this, an outer earth wire is tracked with the cable which is serving as CPC. The core concerns are:
Armouring relative conductivity is compared to the cores which, as the size of cable increases, decreases.
It has health, safety and reliability issues.
Different researches are conducted on the usage of armour. It is analyzed in detail. It is concluded that armouring is the most suitable as CPC as per United Kingdom’s wiring regulations.
Construction of SWA cables
The most common buildings about SWA cable is given as follows:
In most power cables power Cross-Linked Polyethylene (XLPE) is used because of its water resistance and outstanding electrical properties.
It also guarantees that electrodes and other kind of metal substances cannot come closer and make a connection with each other.
Polyvinyl Chloride (PVC) is used as a sheet to give protection to the boundary between the outer and inner coatings of the cable.
Steel Wire Armour (SWA) is used for the mechanical defence of cables or wires. It is cumbersome and hard to bend, so it is used for underground wiring projects.
It is often connected to the earth. It is also used as CPC.
Polyvinyl Chloride (PVC) Sheath is sturdy, and it holds the components composed and also gives defense to the external damage.
SWA construction depends on its intended use.
What do BS5467 and BS6724 stand for?
The terms BS5467 or BS6724 are usually used for SWA. It means that Steel Wire Armoured Cable is suitable for testing and construction according to British Standard requirements.
Multicores of SWA
SWA is only used on multicore cables. Multi Steel Wire Armoured cable is a cable having two or more cores:
| 2-Core SWA Armoured Cable is neutral and lives for Class II. It is Double Shielded utilizations which do not need earth connection. |
| 3-Core SWA Armoured Cables are neutral, live and earth, and it is not like 2-Core. Three core cable is used for Class I or Single Shielded which should have earth connections. |
| 4-Core SWA Armoured Cable is perfectly suitable for low voltage appliances. It is made up of 4 copper individual colour-coordinated cables. |
| 5-Core SWA Armoured Cable is commonly used in small voltage applications. For the power supply, it uses one zone line with the three-zone line. |
| 7-Core SWA Armoured Cable used primarily for low voltage connections and has a max of normal 50Vdc. Each core is made of copper conductors which also have steel armouring inside. |
What are Aluminium Wire Armoured Cables?
SWA is restricted to be used on multicore cable. Aluminium wired Armoured Cables are used in one core cables. These Armoured cables are Nonmagnetic.
SWA is used multicore versions of the cable. When a cable has one core, instead of steel wire, AWA is used which stands for aluminum wire armour.
It is used because aluminum is nonmagnetic. In a single-core cable, a current produces a magnetic field. It would then induce an electric current in a steel wire which could cause overheating.
The current flow in single-core cable produces the magnetic field. This causes an electric current if the steel wire is being used. So, to avoid overheating, you can use Aluminum wired Armoured Cables.
Aluminum wired Armoured Cables have an excellent capacity for storage. These wires assure the transmission.
They also make the input cost much lesser. SSG provides you with better Aluminum power cables at low rates.
What are Copper wire Armoured Cables?
CWA cable is a type of Armoured Cables. These wires have an outer layer made up of copper. These types of cables give voltage up to 35 kV.
Their packaging is done with iron drums or wooden drums. These wires are also used in underground control systems.
As the metal conductivity of copper is second only to silver. It means that after silver-coated wires, copper is best in use.
Likewise silver is much more expensive than other types of metals. So, Copper Armoured cables are the finest and best in every aspect.
As copper wires are cheaper than silver Armoured wires as well as they are good in use.
Copper has the property that it is an excellent conductor of electricity as it has stronger physical properties as well as mechanical strength.
If you are constructing large and high buildings, you should use Copper Armoured Cables.

Chapter 7: What precautionary measures while using Armoured Cables?
There should be better performance and the delicate stability of Armoured Cables. So the manufacturer should search for international standards.
SSG provides some Precautionary process measures of Armoured Cables:
Quality of Armoured wires must be Reliable.
The diameter of the Armoured Cable should not be less than ninety-five per cent of the national width.
The arc width and arc height should be set well. So, the wire will be challenging to lose.
To avoid Armoured cables radial rotation during laying Armoured Cables radial rotation. For this purpose, after the wire armouring, residual torque should be released effectively.
Chapter 8: Why you should be using Armoured Cables over Unarmoured cables?
There are so many reasons to use Armoured Cables over Unarmoured Cables. One of the main reasons is the strength of these cables.
People usually think that there is not a big difference between Armoured Cables and unarmoured cables. They believe the only difference is that Armoured Cables are protected with a metal layer.
In short, the armour shell doesn’t have to be made up of metal. This outer shell can be made up of different materials.
That material can be metal, fibre yarn or glass yarn, etc.
The main difference that makes Armoured Cable different from other cables is that they have an additional outer layer.
Four core Armoured cables are expensive than Unarmoured cables. But they are more efficient.
The Armoured cables made up of steel strip are inexpensive than fibre cables. So it is very beneficial for you to use Armoured Cables.
Armoured cables were used in the past excessively when electric cables were hidden underground. In this age, people need proper channels to stand in previous installing modules.
So, unarmoured cables should be eliminated and should not be used in many applications.
Also, there is a high risk that animals will chew or crush the cables. So, you should use Armoured Cables as they are armoured with a metal coating.
As animals can’t chew the metal, wires will be protected. And a safe transmission can happen.
The other reason you should be using Armoured Cables over unarmoured cables is that these are utilized in the RF environment.
An RF environment contains an off-air signal which is very much reliable and sturdy. There are higher chances that RF signals interfere with your network.
So using the Armoured Cables protects you from this interference.
Why are Armoured Cables beneficial in underground systems?
Are you working with underground power systems? Use Armoured cables. Using unarmoured cables, your wires can cause destruction.
These cables provide extra protection to your wires. They are handy in the installation of fibre optic cables. So you can easily transmit information.
Electricity is supplied through underground cables, even though some of their types work above the earth. Underground wires are resistant against the worst weather, and they can endure the harsh climate.
They are life, low-priced and easy to maintain for they are planted underground. The possibility of their tripping is much less than those of above-ground cables.
If for any reason, overhead lines cannot be fixed, underground cables are the only alternative option then. Their installment costs a lot, but they provide such gainful benefits and features that it seems quite a worthwhile investment.
The armoured underground cables work better for urban lines and can transmit through up to 20 circuits. By comparison, overhead wires go from only 2 to 4 loops.
These cables are protracted since it does not come across with water, acids or alkali like overhead or above-ground wires and cables.
This makes them preferable and much more reliable for use in large cities that needs a constant power supply. The use of an underground wiring system makes urban areas less cluttered and more beautiful.
Further, the land is an asset; therefore, cabling should be done underground so that area can be used for several other purposes when cables are laid beneath the ground and beneath the buildings to which they supply power.
Once had the times, when buildings were jumbled with wires for connections with main supplies.
However, instead of creating messiness and destroying the face of the earth, underground armoured cables provide the handy offer of making the city neater.
They also ensure the safety of people traveling in subways. There are many other advantages of armoured cable. They are noteworthy for the variety in sizes and long term durability.
They even help to keep the urban area clean, ordered and attractive not only for the citizens or residents but also for those who work there.
