Armoured cable uses are widely seen in industrial, commercial, and residential electrical systems because of their strength and durability. Armoured cables have an extra protective metallic layer, usually made of steel or aluminum wire, that safeguards them from mechanical damage, rodents, and harsh environmental conditions. This makes them reliable for underground power supply, outdoor wiring, and heavy-duty industrial use.
In this article, we will explore the major applications of armoured cable and why it is preferred in many electrical systems.
What is Armoured Cable?
Armoured cable is an electrical cable with a protective metal layer that shields conductors from mechanical damage, environmental stress, and enhances safety.
Applications/Uses of Armoured Cables
1. Underground Power Distribution
One of the most common uses of armoured cable is in underground installations. Since underground cables are exposed to soil pressure, stones, and possible digging activities, they need extra protection. The metallic armour ensures the cable does not get damaged easily, maintaining a safe and reliable power supply.
Example: Underground transmission and distribution lines in cities and rural areas.
2. Outdoor Installations
Armoured cable applications are highly suitable for outdoor wiring where weather conditions such as rain, sunlight, or accidental mechanical impacts may damage normal cables. The armour layer resists environmental wear and tear, making it ideal for outdoor electrical projects.
Example: Street lighting systems, outdoor substations, and power supply to garden or farm equipment.
3. Industrial Applications
Industries often have harsh operating environments with heavy machinery, vibrations, and possible risk of physical damage to cables. Armoured cables are preferred here because they can withstand these mechanical stresses while ensuring uninterrupted power flow.
Example: Manufacturing plants, oil refineries, chemical plants, and steel factories.
4. Residential and Commercial Buildings
Armoured cable uses are also common in homes, offices, and commercial complexes for main power supply lines, especially where wiring may be exposed to damage. They provide better safety than unarmoured cables and ensure long-term reliability.
Example: Power supply to lifts, air-conditioning systems, backup generators, and main distribution panels.
5. Substations and Power Plants
In electrical substations and power plants, armoured cables are used for carrying power between transformers, switchgear, and control panels. Their durability and high current-carrying capacity make them ideal for these critical systems.
Example: Low-voltage and medium-voltage connections in substations.
6. Railway and Transport Systems
Armoured cables are also used in railway electrification, metro systems, and airports. They can handle rough usage, vibration, and outdoor exposure, ensuring a reliable power supply to signaling equipment, communication systems, and lighting.
7. Renewable Energy Projects
In solar farms and wind power plants, common armoured cable applications include connecting panels, turbines, and power conditioning units. Since these projects are often located in open fields, the cable armour protects against rodents, soil pressure, and harsh climates.
Advantages of Using Armoured Cable in Applications
- High mechanical strength
- Suitable for underground and outdoor use
- Protection against rodents and accidental damage
- Long life and reliability
- Available in both low-voltage and high-voltage ratings
Conclusion
Armoured cables play a crucial role in safe and reliable power distribution. Common armoured cable uses include underground networks, industrial plants, substations, and renewable energy projects, where they provide durability and mechanical protection that standard cables cannot.
By choosing armoured cables for critical installations, engineers and electricians can ensure long-lasting safety, efficiency, and performance in electrical systems.
