Armoured Cables in Pakistan: Everything You Need to Know

Electrical cables are the backbone of our modern world, powering homes, businesses, and industries. But not all cables are created equal. In demanding environments or areas prone to damage, armoured cables in Pakistan offer superior protection and reliability. Whether you’re a homeowner, contractor, or business owner, understanding armoured cables is crucial for ensuring the safety and longevity of your electrical system.

Benefits of Using Armoured Cables in Pakistan

1. Enhanced Protection: The armour, typically made of steel wires or galvanized steel tape, shields the inner conductors from physical damage caused by rodents, impact, and harsh weather conditions. This is especially important in areas with extreme temperatures, dust, or risk of mechanical stress.

2. Improved Safety: Armoured cables offer increased resistance to electrical faults and short circuits. The metal armour acts as a shield, preventing the flow of electricity beyond the cable and minimizing the risk of fire and electric shock.

3. Long-Term Durability: By protecting the inner conductors from physical and environmental hazards, armoured cables boast a longer lifespan than standard cables. This translates to reduced maintenance costs and more reliable electrical infrastructure.

4. Versatility: Armoured cables suit diverse applications, including underground installations, direct burial, exposed runs, and industrial settings. Their flexibility allows for easy installation in tight spaces and challenging environments.

Types of Armoured Cables Available in Pakistan:

1. Steel Wire Armoured (SWA) Cables: These cables feature galvanized steel wire armour, providing excellent mechanical protection and resistance to rodents. They are ideal for underground installations, ducts, and areas prone to physical damage.

2. Aluminium Wire Armoured (AWA) Cables: This type uses aluminum wires as the armoring material, offering a lighter and more cost-effective option than SWA cables. However, they provide slightly less mechanical protection.

3. Steel Tape Armoured (STA) Cables: These cables utilize corrugated steel tape as the armour, offering excellent flexibility and ease of installation. They are suitable for exposed runs, cable trays, and indoor applications.

4. Lead Sheathed Armoured (LSA) Cables: These cables feature a lead sheath over the inner conductors and additional steel wire armour. They offer superior protection against moisture, chemicals, and corrosion, making them ideal for harsh environments and industrial applications.

Choosing the Right Armoured Cable for Your Project in Pakistan

Several factors influence the type of armoured cable you should choose for your project:

  • Application: Consider where the cables will be installed (underground, exposed, indoors) and the potential hazards it might face (physical damage, rodents).
  • Voltage Rating: Ensure the cable can handle the required voltage for your project.
  • Conductor Material: Choose copper for superior conductivity and aluminium for a cost-effective option.
  • Armour Material: Select the appropriate armour type for strength, flexibility, and weight.
  • Standards and Certifications: Choose cables compliant with relevant Pakistani and international certifications.

Installing Armoured Cables in Pakistan

Proper installation is crucial for the performance and longevity of armoured cables. It’s recommended to consult qualified electricians experienced with handling armoured cables in Pakistan. Here are some key aspects to consider:

  • Cable Routing: Plan the cable route carefully to avoid sharp bends and potential hazards.
  • Preparation: Ensure the cable trench or conduit is properly prepared and debris-free.
  • Installation: Follow the manufacturer’s instructions for proper installation techniques, including cable handling, bending radius, and connection methods.
  • Testing: After installation, it’s crucial to test the cable for continuity, insulation resistance, and earth fault loop impedance.

Maintaining Armoured Cables in Pakistan

Regular maintenance helps ensure the optimal performance and safety of your armoured cables. Here are some essential tips:

  • Visual Inspection: Regularly check the cables for any signs of damage, wear, or corrosion.
  • Testing: Periodically conduct electrical tests to ensure the cable’s integrity and safety.
  • Cleaning: If necessary, clean the cable surface using appropriate methods to prevent dirt and moisture accumulation.
  • Repair: Any damage or faults should be promptly repaired by qualified electricians.


Choosing the right armoured cables in Pakistan requires careful consideration of various factors. By understanding the benefits, types, and installation guidelines, you can make informed decisions for your project. Always prioritize safety and performance by choosing quality cables and consulting experienced professionals for installation and maintenance.
