One of the most frequent forms of electrical cables is an armoured cable. This cable is known for its protective coating, which shields the core from a variety of hazards, including severe tension. The cable is used in a variety of applications, including underground wiring and mains electrical supply. Unfortunately, most of us are ignorant that there are various varieties of armoured cable and instead go for the most common.
An armoured cable is an electrical cable with an additional layer of protection to protect its inside components from abrasion. Essentially, this cable type is more sturdy than standard electrical cables and accomplishes its duty to perfection. Unfortunately, the majority of consumers are disappointed when dealing with this type of cable. When you pick the wrong cable type, you're bound to be disappointed. The majority of people believe that a steel armoured cable is the sole type of armoured cable. Any judgement made based on this premise is almost always incorrect. Cables with armouring are divided into three categories:
1. Steel Wire Armoured Cable (SWA): Steel wire armoured (SWA) is without a doubt the most well-known armoured cable. This cable has a highly conductive copper conductor, an inner sheath made of XLPE or PVC, and an outer sheath made of steel wire armour. Its steel armouring protects it from any mechanical forces that could harm the cable. As a result, while dealing with mains electric supply applications, this armoured electrical cable comes in handy.
Low-voltage and high-voltage varieties of this cable are available from armoured cable producers. The low-voltage version can handle up to 11 kV, while the high-voltage version can handle up to 33 kV. It would be better if you make your decision depending on the cable you intend to use. Because this cable is heavy and difficult to bend, it is better used as a grounding armoured cable.
2. Steel Tape Armoured Cable (STA): This armoured cable is designed for wiring applications that do not demand more than 35kV of electricity. Steel tape armouring is used to protect the cable's outer sheath. STA cables are less expensive than SWA cables because they are easier to make. However, it's not a good idea to prioritise the armoured cable's price over its fit for your application. If you need to do some wiring in a vermin and termite-infested region, this wire is appropriate. It's also used in building, underground mining, and petrochemical applications.
Before you choose an armoured cable, be sure that its minimum bending radius is appropriate for your application. An armoured electrical cable, regardless of its classification, must not bend less than the manufacturer's minimum bending radius. The cable's outside sheath frequently displays the cable's minimum bending radius.
3. Aluminium Armoured Cable: Because it is only suitable for single-core wires, aluminium armoured wire cable is not widely used. Because of its non-magnetic characteristics, aluminium armouring is suited for single-core applications. In a single-conductor cable, any attempt to apply steel armouring will result in overheating.
Mechanical dangers are well protected by an armoured cable. As a result, you can utilise this type of electrical cable in regions where mechanical damage is a concern. To mention a few, these sites include exterior walls, underground, and industrial establishments.
The strength and ability to endure various sorts of external extremities are the defining characteristics of any armoured cable wiring. UV radiation, water, rat infestations, and numerous mechanical risks are common examples of such extremes. In most cases, armoured wires do not necessitate the usage of conduits. Some local codes, on the other hand, require the use of pipes for all underground installations. As a result, before starting any subterranean wiring project, double-check your local wiring laws.
You should be aware that there are several types of armoured cables, each with its purpose. An armoured fire alarm wire, for example, is only used in alarm wiring applications. An armoured marine cable, on the other hand, is perfect for maritime-related applications. Simply put, you must make a decision depending on your wiring requirements.
In the absence of conduits, armour-clad cable wires provide appropriate protection and durability. Most people are forced to use conduits in regions where external dangers like corrosion and cable abrasion exist. As a result, it is correct to assert that an armoured cable is appropriate for usage in hazardous environments. Want to purchase good quality industrial cables?
