Armoured Cable

An Armoured Cable is a vital component in electrical and communication systems, known for its durability and ability to protect cables in various environments. This comprehensive guide explores the world of Armoured Cables, covering their definition, construction, materials, applications, advantages, types of armour, installation, maintenance, common issues, and solutions.

What is an Armoured Cable?

An Armoured Cable is a specialized type of electrical or communication cable designed with a protective layer or armor. This armor is typically made of metal or other robust materials and encases the internal cables, shielding them from physical damage, moisture, and other environmental factors.

Construction and Materials

The construction of Armoured Cables involves several key components:

  • Conductors: These are the core cables that carry electrical or data signals. They are typically made of copper or aluminum, chosen for their excellent conductivity.
  • Insulation: Surrounds the conductors to prevent electrical contact and protect against heat, moisture, and other potential damage. The insulation material can vary based on the cable’s intended use.
  • Armour: The outer protective layer, which can be made of steel, aluminum, or other materials. The choice of armor depends on the cable’s application and environmental requirements.
  • Jacket: An optional outer layer for additional protection, which may be added based on specific needs, such as resistance to UV exposure or chemicals.

Applications of Armoured Cables

Armoured Cables are used in various applications, including:

  • Underground Wiring: They are commonly employed for burying electrical or communication cables underground to protect them from moisture and physical damage.
  • Industrial and Construction Sites: Armoured Cables are used in demanding industrial environments and construction sites where robust protection is essential.
  • Submersible Applications: They are suitable for applications where cables may be submerged in water, such as underwater lighting or pump installations.
  • Outdoor Installations: Armoured Cables are chosen for outdoor installations where they must withstand exposure to the elements.

Advantages of Armoured Cables

Armoured Cables offer various advantages, including:

  • Physical Protection: They shield cables from physical damage, making them ideal for challenging environments.
  • Moisture Resistance: Armoured Cables are designed to resist moisture and water, ensuring uninterrupted performance in damp conditions.
  • Durability: They are built to withstand wear and tear, ensuring a long service life even in harsh environments.

These advantages make Armoured Cables an essential choice in many industries.

Types of Armour

Armoured Cables come in various types of armor, including:

  • Steel Wire Armour (SWA): SWA cables feature steel wires wound around the core, offering robust protection.
  • Aluminum Wire Armour (AWA): AWA cables use aluminum wires for protection, which is lighter but still effective.
  • Lead Sheathed Armour: These cables feature a lead sheath for exceptional protection in corrosive environments.

Installation and Maintenance

Proper installation and regular maintenance of Armoured Cables are crucial for safe and reliable electrical or communication systems. This section provides guidance on the correct installation procedures and maintenance practices to prevent issues and ensure long-term performance.

Common Issues and Solutions

Despite their durability, Armoured Cables may encounter common issues, such as cuts, damage, or corrosion. This section outlines these issues and provides solutions to address and prevent them, ensuring continued performance and safety.


Armoured Cables are essential components for protecting and ensuring the reliability of electrical and communication systems in demanding environments. This guide has provided a comprehensive overview of Armoured Cables, including their definition, construction, materials, applications, advantages, types of armor, installation, maintenance, common issues, and solutions. Understanding these aspects is crucial for selecting the right cables for specific needs and ensuring safe and effective installations.
