Why Choose Aluminum Strip as a Protective Cover for Armored Cables?

Armored cables are crucial materials for electrical transmission, widely used in industries, construction, mining, and other fields. The design purpose of armored cables is to protect internal conductors from external environmental interference while transmitting power. There are many advantages to using aluminum strip as the protective covering for armored cables, and below we elaborate on these reasons.

Lightweight Advantage of Aluminum Strip

Aluminum has a much lower density compared to steel, making it especially important in the application of armored cables. This lightweight characteristic not only reduces the manpower and material requirements during transportation and installation but also allows for greater flexibility in overall structure, facilitating layout adjustments even in complex environments. This is particularly significant for large projects where installations may occur at heights or in confined spaces.

Excellent Corrosion Resistance

In many industrial environments, cables might be exposed to moisture, corrosive gases, or chemicals. The surface of aluminum naturally forms an oxide layer that effectively resists the intrusion of oxygen and moisture, reducing the risk of cable failures due to environmental factors. This superior corrosion resistance means that aluminum-stripd armored cables can be safely used in various harsh environments, ensuring long-term stability in power transmission.

Good Conductivity

While aluminum’s conductivity is lower than that of copper, its relatively low resistance can meet most electrical transmission requirements. In fact, in certain situations, using aluminum as a conductive material can provide significant economic benefits. Furthermore, aluminum strip can also serve as a grounding line, lowering resistance and enhancing the safety of electrical systems, particularly in cases of leakage or short circuits.

High Tensile Strength

Aluminum strip possesses high tensile strength, allowing it to withstand substantial external forces, ensuring that it does not easily damage during transportation or use. This characteristic is especially suitable for applications where mechanical pressure or tension is involved, such as underground or overhead cables. Additionally, this robustness can reduce the likelihood of accidents, safeguarding the surrounding personnel.

Economic Considerations

The production and processing costs of aluminum are generally lower than those of other metals, making aluminum strip economically attractive as a protective material. This is particularly true in large-scale production, where using aluminum can significantly reduce overall manufacturing costs. Moreover, the durability and corrosion resistance of aluminum mean that its maintenance costs are relatively low, further enhancing return on investment.

Ease of Processing

Aluminum has favorable processing properties, making it easy to shape, weld, and connect. This not only improves production efficiency but also ensures consistency and reliability in the manufacturing process of armored cables. With advancements in production technology, the processing methods for aluminum strip have become increasingly diverse, allowing for more complex shapes and structures in armored cables.

Electromagnetic Interference Resistance

During power transmission, external electromagnetic interference can negatively impact signal quality. Aluminum strip provides a certain level of shielding, reducing external interference and enhancing the cable’s resistance to disturbances. This makes armored cables particularly suitable for applications that require stringent signal stability, such as in industrial automation control systems and communication devices.

Conclusão

In summary, choosing aluminum strip as the protective cover for armored cables is a result of comprehensive consideration of various environmental and economic factors. The lightweight nature, corrosion resistance, good conductivity, high tensile strength, economic advantages, ease of processing, and excellent resistance to electromagnetic interference of aluminum strip make it an ideal material for armored cables. As the demand for power continues to grow across industries, the application of armored cables will become increasingly widespread, and the use of aluminum strip will continue to provide strong protection for safe and stable power transmission.
