What is Armoured Cable used for?

Armoured cable is a type of electrical cable designed for robust and harsh environments, offering enhanced protection and durability compared to standard cables.Its key feature is an extra layer of protection, the 'armour', which sits between the internal conductors and the outer sheath.This armour is typically made of steel or aluminum and provides significant resistance to physical damage.

Key Uses of Armoured Cable

Armoured cables are essential in scenarios where electrical wiring is at risk of mechanical stress, impact, moisture, chemicals, or even rodent damage.Here are some of the primary applications:

• Underground Power Distribution: Armoured cables are ideal for burying directly underground.The armour layer provides excellent protection against soil moisture, chemicals present in the ground, and physical damage from digging or ground movement.⁶This makes them a reliable choice for underground power networks and street lighting systems.
• Industrial and Construction Sites: These environments are characterized by heavy machinery, equipment, and rigorous activities that pose a high risk of cable damage.Armoured cables are extensively used here to ensure a safe and uninterrupted power supply, minimizing downtime and enhancing safety.
• Outdoor Lighting and Security Systems: For outdoor installations like garden lighting, security systems, and CCTV cameras, armoured cables offer crucial weather resistance and durability.They withstand exposure to sunlight, rain, and temperature fluctuations, ensuring long-term reliability for outdoor electrical systems.¹¹
• Power Distribution in Buildings: In commercial and industrial buildings, armoured cables are used for main power distribution.Their robust nature ensures a stable and safe electrical supply throughout the building, capable of withstanding the demanding conditions of these environments.
• Hazardous Locations: Armoured cables are recommended for use in hazardous areas such as stairwells, barns, and basements, where cables might be exposed to physical stress or environmental hazards. They provide an extra layer of safety in locations with increased risk of damage.
• Marine and Offshore Installations: The harsh conditions of marine and offshore environments demand robust cabling solutions.¹⁵Armoured cables are used in these applications due to their resistance to moisture, chemicals, and physical stress, ensuring reliable power and signal transmission in demanding marine settings.
• Information Transmission: Beyond power, armoured cables are also used for data and signal transmission.This includes applications in local telephone lines, TV cables, electronic cables, radio frequency cables, fiber optic cables, and data or composite cables.The armour ensures secure and reliable data transmission, especially in environments where cables might be exposed to physical threats.

Benefits of Using Armoured Cable

The use of armoured cable brings several key advantages:

• Enhanced Protection: The primary benefit is superior protection against mechanical damage, including crushing, impact, and abrasion.This protection extends the lifespan of the cable and reduces the risk of electrical faults caused by physical damage.
• Durability and Longevity: Armoured cables are designed to withstand harsh environmental conditions, including moisture, chemicals, and extreme temperatures.This durability translates to a longer service life and reduced maintenance needs, especially in challenging installations.
• Safety: By minimizing the risk of damage to conductors, armoured cables enhance electrical safety.They reduce the chances of short circuits, electrical fires, and electrocution, particularly in demanding or hazardous environments.
• Versatility: Armoured cables are versatile and can be used in a wide range of applications, from power distribution to data transmission, and in diverse settings from underground to industrial to marine.
• Reliability: The robust protection offered by armoured cables ensures a more reliable electrical and data transmission system, reducing the likelihood of interruptions and system failures.

In summary, armoured cable is a vital component in modern electrical installations where enhanced protection and durability are paramount.Its robust construction and versatile applications make it an essential choice for ensuring safety and reliability in a wide range of demanding environments.
