Armoured Cabling
Armoured cabling, a type of electrical cable protected by a layer of metal sheathing, provides superior durability and protection in harsh environments. Its robust design makes it suitable for various applications, from industrial to maritime sectors. This article explores the benefits of armoured cabling, the different categories and classes, and its critical role in various industries.
Benefits of Armoured Cabling
Enhanced Durability
Armoured cables are designed to withstand mechanical stress, physical damage, and harsh environmental conditions. The metallic armor protects the internal conductors from impacts, abrasions, and other external forces, ensuring long-lasting performance.
Superior Protection
The metal sheath in armoured cabling acts as a barrier against rodents, moisture, and chemicals, preventing corrosion and degradation. This protection is crucial in environments where cables are exposed to potential hazards.
Fire Resistance
Many armoured cables are designed to be fire-resistant, capable of maintaining circuit integrity even in high-temperature conditions. This feature is vital for ensuring safety and continuity of critical operations during fire incidents.
Electromagnetic Interference (EMI) Shielding
The metallic armor also serves as a shield against electromagnetic interference, reducing the risk of signal degradation and ensuring reliable data transmission in environments with high electrical noise.
Flexibility and Ease of Installation
Despite their rugged construction, many armoured cables are designed to be flexible, making them easier to install in various settings. This flexibility reduces installation time and costs.
Categories of Armoured Cable
Armoured cables are categorized based on their construction and the type of protection they offer:
Categories of Armoured Cable
Steel Wire Armoured (SWA) Cable
SWA cables feature a layer of steel wire around the conductors, providing excellent mechanical protection. They are commonly used in power distribution networks and are suitable for both underground and overhead installations.
Aluminium Wire Armoured (AWA) Cable
AWA cables use aluminium wire for armoring, making them lighter than SWA cables. They are typically used in applications where weight is a concern, such as in long-distance power transmission.
Steel Tape Armoured (STA) Cable
STA cables have a layer of steel tape around the conductors, offering good protection against mechanical damage. They are often used in industrial environments where cables are subject to physical stress.
Classes of Armoured Cable
Armoured cables are also classified into different classes based on their intended use and performance characteristics:
Classes of Armoured Cable
Class 1
These cables are designed for fixed installations in buildings and industrial settings. They provide reliable protection against mechanical damage and are commonly used in power distribution systems.
Class 2
Class 2 cables are intended for use in environments where there is a higher risk of mechanical stress or exposure to harsh conditions. They offer enhanced durability and protection, making them suitable for underground and outdoor installations.
Class 3
These cables are designed for the most demanding environments, including heavy industrial and marine applications. They provide the highest level of protection against physical and environmental damage.

Applications in Various Sectors
Armoured cabling is utilized in a wide range of sectors due to its robust design and protective features:
Industrial
In industrial settings, armoured cables are essential for ensuring reliable power and data transmission in environments where cables are exposed to heavy machinery, chemicals, and extreme temperatures. They are used in manufacturing plants, refineries, and processing facilities.
Construction
On construction sites, armoured cables provide durable and safe electrical connections for temporary and permanent installations. Their resistance to physical damage and environmental hazards makes them ideal for use in building infrastructure.
Energy
Armoured cables are crucial in the energy sector for transmitting electricity from power plants to substations and distribution networks. Their ability to withstand harsh conditions ensures reliable power delivery even in remote and challenging locations.
Transportation
In the transportation sector, armoured cables are used in railways, airports, and highways to provide power and communication links. Their robustness ensures continuous operation and safety in these critical infrastructure systems.
Maritime
Armoured cabling is particularly important in maritime environments, where cables are exposed to saltwater, mechanical stress, and extreme weather conditions. They are used in ships, offshore platforms, and underwater installations to ensure reliable power and data transmission. The protective armor prevents corrosion and damage, maintaining the integrity of the cables in harsh marine conditions.
Importance in Maritime Sector
In the maritime sector, the importance of armoured cabling cannot be overstated. Ships and offshore platforms rely on robust and reliable cabling for various critical functions, including power distribution, navigation systems, communication networks, and safety systems. Armoured cables provide the necessary protection against the corrosive effects of saltwater and mechanical damage caused by waves, marine life, and other environmental factors.
Moreover, armoured cables ensure the safety and operational efficiency of maritime vessels and installations. In the event of an emergency, such as a fire or collision, the fire-resistant properties of armoured cables help maintain vital communication and power systems, enabling swift response and mitigation measures.
Conclusion
Armoured cabling offers numerous benefits, including enhanced durability, superior protection, fire resistance, and EMI shielding. The various categories and classes of armoured cables cater to different applications, ensuring reliable performance in diverse environments. From industrial and construction sectors to energy, transportation, and maritime industries, armoured cables play a crucial role in maintaining safe and efficient operations. Their robust design and protective features make them indispensable in environments where reliability and durability are paramount.
