company news about Armored cable and unarmored cable - how to choose the most suitable power transmission solution according to needs?

In power transmission and distribution systems, the choice of cables directly affects power supply safety, system stability and long-term maintenance costs. As the two mainstream types, armored cables and unarmored cables each have unique advantages and applicable scenarios. So, which cable is more suitable for your project? This article will deeply analyze the core differences between the two to help users make scientific decisions.

Armored cable: Born for harsh environments
Armored cables are named because of their outer metal armor layer (such as steel belt or steel wire) and have strong mechanical protection capabilities. This structure enables it to withstand soil pressure during direct burial, rodent bites, and even accidental external force impacts during construction. In addition, the metal armor layer can effectively shield electromagnetic interference and is suitable for scenarios with extremely high requirements for safety and stability, such as high-voltage power transmission, mining, and petrochemicals.

However, armored cables also have problems such as heavy weight, poor flexibility, and high cost, and if the metal layer is not properly treated for corrosion, the life may be affected by rust.

Unarmored cable: a lightweight and economical conventional choice
Unarmored cable has a simple structure and consists only of a conductor, an insulating layer and a sheath, so it is light, flexible and low in cost. It is widely used in stable environments such as indoor power distribution, bridge laying, and electrical equipment connection. For example, commercial buildings, home decoration, and mobile device power supply systems usually give priority to unarmored cables.

However, it should be noted that unarmored cables have weak resistance to mechanical damage and require additional protective sleeves when used in outdoor direct burial or in areas susceptible to external damage.

Expert advice: Scientific selection based on scenarios
Power engineering experts pointed out that cable selection needs to comprehensively consider the laying environment, budget and long-term maintenance costs:

Scenarios where armored cables are preferred: direct underground burial, industrial plants, tunnels, mines and other high-risk environments.

Scenarios where unarmored cables are preferred: indoor dry environments, short-distance power distribution, and mobile devices that require frequent bending.

In addition, users should also pay attention to the compliance of cables to ensure compliance with national standards (such as GB/T 12706) or international specifications (such as IEC 60502).

Future trends: Application of high-performance materials
With the development of material technology, new composite armor (such as aluminum tape armor) and high-temperature resistant sheath materials are becoming more popular, further balancing protection performance and cost. At the same time, the rise of intelligent cable monitoring systems also allows users to manage cable health more efficiently and reduce the risk of failure.

Conclusion
Whether it is armored or unarmored cable, its core goal is to provide safe and efficient transmission solutions for power systems. Users should choose the most matching cable type based on actual needs and combined with professional opinions to ensure the long-term and reliable operation of the power supply system.
