Armoured cables are a type of electrical cable that have a mechanical protection layer that prevents damage from physical impact, water and other environmental factors. They are made up of different layers of materials that each serves a different purpose. Armoured cables are used in a wide range of settings, including industrial and commercial applications. In this article, we will discuss how armoured cables work, their benefits, and some of the common applications for them.
How armoured cables Work
Armoured cables are constructed using a variety of materials including copper, aluminium, steel wire, lead, or polymer. The conductor is the part of the cable that carries the electrical current and is usually made of copper or aluminium. The insulation is the layer that surrounds the conductor to prevent short circuits and is often made from a polymer such as PVC.
The mechanical protection of an armoured cable is its most important feature. The armour layer is typically made of steel wire, aluminium or polymer. This layer serves to prevent the cable from being damaged by physical stresses such as crushing, bending or piercing. Armoured cables can also be designed to be resistant to chemical, water and fire hazards.
Benefits of armoured cables
Armoured cables offer a number of advantages over their non-armoured counterparts. For one, the mechanical protection layer ensures that these cables are rugged and durable, making them ideal for use in harsh environments, such as mines, oil rigs, industrial plants, and construction sites.
The insulated core provides a secure and reliable electrical current transfer, while preventing damage from short circuits. Moreover, most armoured cables can be used both indoors and outdoors, as they are resistant to moisture and humidity, and can withstand extreme temperatures.
Applications of armoured cables
Armoured cables are used in a wide range of applications. Among the most common are power transmission and distribution systems, which require cables that can withstand high and low voltages. These cables can be used to connect electrical grids, transformers and power generators, and to transfer power to different parts of a building.
Another common application for armoured cables is in the transportation industry, especially in vehicles such as buses, trains and airplanes. These cables are designed to withstand constant movement and vibrations, while also ensuring that electricity is delivered safely to all areas of the vehicle.
Armoured cables are also found in many mining, construction and industrial applications, where they provide reliable power to heavy machinery and equipment. These cables are often used in challenging underground environments, where they are subjected to high temperature and pressure conditions.
In addition, armoured cables are a common choice for telecommunications networks, as they provide the durability and reliability required for communication systems that operate in harsh outdoor environments. Armoured fibre optic cables are particularly useful in these types of situations, as they are designed to withstand extreme weather conditions, moisture, and accidental impacts.
Types of Armoured Cables
Armoured cables come in different types and designs, each suited to specific applications. The most common types of armoured cables include steel wire armoured (SWA), aluminium wire armoured (AWA), lead sheathed armoured, and fibre optic armoured cables.
The SWA is the most widely used type of armoured cable owing to its flexible design and cost effectiveness. The AWA is similar to the SWA but is made of aluminium instead of steel. This makes it more lightweight, but also less durable compared to the SWA.
Lead sheathed armoured cables are typically used in applications that require a degree of electromagnetic compatibility. They are often used in areas where there are high levels of electromagnetic interference caused by motors, transformers, or other power equipment.
Fibre optic armoured cables are designed for telecommunications networks and are highly resistant to moisture, rodents, and insects. They are also capable of transmitting data over longer distances, making them ideal for connecting large-scale communication networks.
Conclusion
Armoured cables are an essential component in many electrical systems, providing reliable power and data transmission in harsh and challenging environments. With their durable construction, mechanical protection, and reliable performance, they can be used in a wide range of applications, from power transmission and distribution systems to telecommunications networks and transportation vehicles. As technology advances, armoured cables will continue to play an important role in the development and implementation of many new and innovative applications.
