What Are Armoured Electrical Cables? Understanding Their Uses and Benefits

Armoured electrical cables are essential components in modern electrical installations. They provide enhanced protection against physical damage and environmental factors. This makes them ideal for both industrial and residential applications where safety, durability, and reliability are key.

What Is an Armoured Electrical Cable?

At its core, an armoured electrical cable features an additional layer of metal protection, known as the "armour." This metal layer can be made from materials like steel or aluminium. The armour serves to shield the inner conductors from external damage caused by mechanical stress, impact, moisture, or chemicals. The typical structure of an armoured cable consists of:

• Inner Conductors: These carry the electrical current.

• Insulating Layer: It prevents shorts and maintains safety.

• Protective Armour: A metal sheath, usually made of steel or aluminium, that provides mechanical protection.

• Outer Sheath: This adds an extra layer of protection against environmental conditions.

The presence of the armoured layer is what sets armoured cables apart from standard cables. This layer ensures the cable remains intact even in challenging environments.

Why Are Armoured Electrical Cables Used?

The primary purpose of armoured electrical cables is to provide enhanced mechanical protection. These cables are designed to withstand tough conditions such as outdoor installations, direct burial, and areas with high risk of physical damage. Some common applications include:

1. Power Systems: Armoured cables are widely used in power systems to connect power supplies to electrical equipment, ensuring safe and efficient electricity distribution.

2. Information Transmission: Armoured cables are also used for information transmission systems, including telephone lines, data cables, and optical fiber cables.

3. Industrial Settings: In factories, construction sites, and warehouses, where cables are often exposed to mechanical stresses, armoured cables are the preferred choice.

Whether buried underground or exposed to the elements, armoured cables offer reliable protection, ensuring that power transmission remains uninterrupted and safe.

Benefits of Armoured Electrical Cables

Armoured cables offer several significant advantages over traditional, unarmoured cables. Let's explore why they are often the go-to choice for installations in demanding environments.

1. Increased Durability and Protection

The metal armouring significantly increases the cable's durability. Unlike unarmoured cables, which can easily be damaged by impact, mechanical stress, or animal bites, armoured cables are designed to withstand these forces. This makes them ideal for use in industrial and outdoor settings where cables are more likely to be exposed to physical harm.

2. Resistance to Harsh Conditions

Armoured cables are designed to perform in harsh conditions. Whether exposed to extreme temperatures, moisture, or corrosive chemicals, the robust construction of armoured cables ensures they continue to function reliably. This makes them ideal for use in industries like construction, mining, and offshore drilling.

3. Long Lifespan

The strength and protection offered by armoured cables contribute to their longevity. These cables are less likely to need frequent replacements compared to non-armoured alternatives. Their durable design makes them an excellent long-term investment for both residential and industrial applications.

4. Flexibility and Easy Installation

While armoured cables are highly protective, they remain flexible enough to be installed in various environments. Unlike rigid conduits, armoured cables can navigate tight spaces and complex layouts. This makes them easier to install, reducing the time and cost associated with installation.

Applications of Armoured Cables

Armoured cables are versatile and can be used in various applications. Some of the key areas where armoured cables are commonly used include:

• Underground Installations: Armoured cables are ideal for direct burial, protecting the internal conductors from soil corrosion, moisture, and physical damage.

• Outdoor Installations: Whether it's powering outdoor lighting or connecting outbuildings to the main power supply, armoured cables are well-suited for outdoor use due to their ability to withstand environmental factors.

• Industrial Sites: Factories, warehouses, and construction sites often require armoured cables to ensure that the electrical systems remain safe from mechanical damage.

• High-Traffic Areas: Armoured cables are also used in places with high foot traffic, such as schools or hospitals, where safety is a top priority.

Choosing the Right Armoured Cable

When selecting an armoured cable, it's essential to consider the specific needs of your installation. There are different types of armoured cables available:

• Steel Wire Armoured (SWA): Provides high mechanical protection and is ideal for underground and outdoor applications.

• Aluminium Wire Armoured (AWA): Lighter than SWA cables, making them suitable for long-distance power transmission.

• Steel Tape Armoured (STA): Offers a thinner layer of protection, suitable for indoor installations or where space is limited.

Each type of armoured cable is designed to meet specific requirements, so it's essential to choose the right one for your application.
