In today's technologically advanced world, cables play an integral role in transmitting power and data signals. Armoured and unarmoured cables are two types of cables designed for specific applications. In this blog, we will delve into the differences between these cables, shedding light on their unique features and use cases.

Armoured Cables:

Armoured cables are power cables protected by an external metal sheath, typically made of steel wires or aluminum. These cables are renowned for their robustness and resistance to mechanical damage, making them ideal for harsh environments and installations that demand enhanced durability.

1. Construction:

The construction of an armoured cable involves layering various components. At its core, there is a conductor, usually copper or aluminum, responsible for carrying the electrical current. Insulation materials are then used to isolate the conductor and prevent short circuits. Surrounding the insulation, there may be one or more metallic layers providing additional protection. Finally, a solid metal sheath is tightly wrapped around the cable to shield it from external physical stress.

2. Mechanical Protection:

The primary purpose of an armoured cable is to safeguard the internal components against external threats. The metal sheath provides excellent resistance to impacts, moisture, rodents, and even accidental digging during installations. These cables are commonly used in industries, construction sites, and underground applications where they offer reliable protection.

3. Electrical Insulation:

Apart from physical protection, armoured cables offer superior electrical insulation. Depending on the specific application, they can be designed to withstand high voltage levels, making them suitable for transmission and distribution of electricity. Additionally, their insulation materials exhibit low capacitance, enabling efficient transmission of power over long distances without any significant losses.

Unarmoured Cables:

Unarmoured cables, on the other hand, do not possess the external metal sheath found in armoured cables. Instead, they rely on various layers of insulation materials to protect the inner conductors. These cables are widely used in less demanding applications where mechanical protection is not a key requirement.

1. Construction:

Unarmoured cables are simpler in construction compared to their armoured counterparts. They consist of a conductor surrounded by one or more layers of insulation materials, ensuring electrical and environmental protection. While they lack the metallic reinforcement, unarmoured cables remain highly flexible and lightweight, making them easier to handle during installations.

2. Use Cases:

Unarmoured cables find their applications in less physically challenging environments, such as indoor electrical wiring, office spaces, homes, and telecommunications. They are commonly employed for data and signal transmission, carrying relatively low power levels. Their flexibility allows for convenient routing and installation across varied spaces.

3. Cost-Effectiveness:

Due to their simplified construction, unarmoured cables are generally less expensive compared to armoured cables. This affordability makes them a popular choice for residential and commercial projects, especially when enhanced mechanical protection is not essential.

Conclusion:

In summary, armoured and unarmoured cables offer distinct advantages depending on the specific requirements of a project. Armoured cables provide exceptional mechanical protection, high levels of durability, and enhanced insulation for power transmission in rugged environments. Unarmoured cables, on the other hand, focus more on cost-effectiveness and flexibility without compromising basic electrical insulation.

Understanding the differences between these two cable types is crucial for professionals and individuals involved in electrical installations. By selecting the appropriate cable based on the specific environment and application, one can ensure both efficient power transmission and optimal protection for the electrical system.
