Armoured Electrical Wires and Non-armoured Electrical Wires: A Comparison and Characteristics of Two Types of Cables

Armoured electrical wiress and ordinary non-armoured electrical wires are two major categories in the world of cables. Cables, which are widely used in various fields, not only come in many specifications and models but also have different characteristics. Among them, armoured electrical wires and ordinary non-armoured electrical wires are two significant distinctions. So, what is the difference between these two types of cables? And what are their respective features? Next, we will delve into the differences between these two types of cables and their unique characteristics.

Characteristics of Armoured Electrical Wires

Armoured electrical wires, as a type of cable with an additional metal protective layer, enhance their physical and electromagnetic protection performance through metal wire braiding or metal tape wrapping. This design allows armoured electrical wires to better adapt to various special environments or application needs, ensuring stable transmission under harsh conditions. Its core features include excellent protection, durability, and adaptability in special occasions.

• Physical Protection: The outer layer of the armoured electrical wire is made of metal material, providing additional physical protection to effectively resist mechanical damage, pulling, and pressure.

• Electromagnetic Shielding: This metal layer also has electromagnetic shielding functions, significantly reducing electromagnetic interference, thus ensuring high-quality data transmission.

• Application Fields: Due to its excellent protective performance, armoured electrical wires are often used in scenarios requiring additional protection, such as industrial fields, underground cable laying, subways, and submarine communications.

• Durability: Thanks to its metal outer layer, the armoured electrical wire exhibits exceptional durability and can work stably for a long time in harsh environments.

Non-Armoured Electrical Wires

Non-armoured electrical wires, as standard cables, mainly consist of insulation materials, conductors, and outer sheaths, but unlike armoured electrical wires, they do not have a metal outer protective layer. Their characteristics are as follows:

• Flexibility: Due to the absence of a metal outer layer, non-armoured electrical wires show extremely high flexibility, making them very suitable for applications requiring frequent bending or movement.

• Cost-effectiveness: Compared with armoured electrical wires, non-armoured electrical wires are more affordable, making them an ideal choice for general purposes.

• Wide Application: Non-armoured electrical wires are widely used in residential, commercial buildings, and data centers. In these locations, their simple structure is sufficient to meet daily needs without the need for additional physical or electromagnetic protection.

• Easy Installation: Thanks to their excellent flexibility and moderate size, non-armoured electrical wires are generally easier and more efficient to install.

How to Choose the Right Type of Cable

When choosing between armoured electrical wires and non-armoured electrical wires, you need to consider the following key factors:

• Application Needs: The first consideration is the environment and intended use of the cable. If additional physical or electromagnetic protection is required, it is recommended to choose an armoured electrical wire.

• Cost Budget: The price of armoured electrical wires is generally higher than that of non-armoured electrical wires.

• Cable Diameter and Flexibility: Consider the diameter and bending performance of the cable to ensure it meets specific installation requirements.

• Electromagnetic Interference: If electromagnetic interference is a key issue in the application scenario, then an armoured electrical wire would be a more suitable choice.

In summary, when choosing between armoured electrical wires and non-armoured electrical wires, you need to comprehensively consider the above four aspects.
