Introduction:
When it comes to wiring installations, safety is a top priority. This is where armoured cables come into play. Armoured cable are widely used in various industrial, commercial and residential applications. They are designed to provide robust protection to the cables and to ensure safety, especially in hazardous environments. In this blog, we will discuss what is an armoured cable is, its benefits, and its various applications.
What is an Armoured Cable?
An armoured cable is a type of electrical cable that has an additional layer of protection, usually made of steel or aluminum. This additional layer protects the cable from damage caused by external factors, such as moisture, extreme temperatures, impact, and abrasion. The armor can also act as a barrier against rodents and other pests that can damage the cable.
Benefits of Armoured Cables:
Here are the benefits of armoured cables:
1. Robust Protection:
The primary benefit of using armoured cables is that they provide robust protection to the cables, ensuring they are not easily damaged. This makes them ideal for installations in harsh environments.
2. Safety:
Armoured cables are designed to prevent electrical faults and short circuits. This is because the armor layer provides an extra layer of insulation, which reduces the risk of electrical shock and fire hazards.
3. Durability:
Armoured cables are durable and long-lasting. They can withstand harsh conditions, making them ideal for use in areas where there is heavy foot traffic, or where the cables are exposed to the elements.
4. Versatility:
Armoured cables can be used in various applications, including power distribution, lighting, and communications. They are also suitable for use in underground, overhead, and outdoor installations.
5. Cost-Effective:
Although armoured cables may be more expensive than standard cables, they are a cost-effective solution in the long run. They require less maintenance, have a longer lifespan, and provide added safety benefits.
Applications of Armoured Cables:
Armoured cables are used in a wide range of applications, including:
- Power distribution in commercial and industrial buildings
- Wiring for outdoor lighting, security systems, and CCTV cameras
- Underground installations in high voltage areas
- Marine and offshore installations
- Railway and transport systems
- Mining and quarrying operations
What are the Two Types of Armoured Cable?
1. Steel Wire Armoured (SWA) Cable:
This type of cable has a layer of steel wire armor that provides protection against mechanical damage, such as impact and abrasion. The armor layer is wrapped around the cable and is usually made of galvanized steel wire. SWA cables are commonly used in industrial and commercial applications for power distribution and underground installations.
2. Aluminium Wire Armoured (AWA) Cable:
This type of cable has a layer of aluminum wire armor that provides protection against mechanical damage and corrosion. The armor layer is wrapped around the cable and is usually made of aluminum wire. AWA cables are commonly used in areas where the cable is exposed to corrosive environments, such as offshore installations, and in applications where weight is a consideration, such as high-rise buildings.
What is the Difference Between Armoured Cable and Normal Cable?
The following are some of the key differences between armoured cable and normal cable:
1. Protection:
The primary difference between armoured cable and normal cable is the level of protection provided. Armoured cable has an additional layer of protection, usually made of steel or aluminum, that offers robust protection against external factors such as moisture, extreme temperatures, impact, and abrasion. Normal cable, on the other hand, does not have this extra layer of protection.
2. Durability:
Armoured cables are generally more durable than normal cables. The additional layer of protection makes them more resistant to damage from external factors and increases their lifespan. Normal cables are more prone to damage, particularly in harsh environments.
3. Safety:
Armoured cables are designed to provide added safety benefits. The armor layer acts as an extra layer of insulation, reducing the risk of electrical shock and fire hazards. Normal cables do not offer this added safety feature.
4. Cost:
Armoured cables are generally more expensive than normal cables due to the additional layer of protection they provide. However, they are a cost-effective solution in the long run as they require less maintenance and have a longer lifespan.
5. Versatility:
Armoured cables are more versatile than normal cables. They can be used in various applications, including power distribution, lighting, and communications. They are also suitable for use in underground, overhead, and outdoor installations. Normal cables are more limited in their applications.
Overall, the key difference between armoured cable and normal cable is the level of protection provided. Armoured cable offers robust protection against external factors, increased durability, added safety benefits, and more versatility, making them a suitable choice for various industrial, commercial, and residential applications.
Conclusion: What is an Armoured Cable
In conclusion, armoured cables are an essential component of electrical installations. They provide robust protection to cables, ensuring they are not easily damaged and reduce the risk of electrical faults and short circuits. Additionally, armoured cable gland are durable, versatile, and cost-effective in the long run. They can be used in a wide range of applications, including power distribution, lighting, and communications. By choosing armoured cables, you can ensure that your wiring installations are safe, secure, and long-lasting.
