Armored Copper Strip Features and Advantages

Armored Copper Strip Applications

Provides excellent mechanical protection and shielding performance, ensuring the stability and durability of power transmission.

High temperature and corrosion resistance, providing a robust armored shell for cables in extreme environments.

Optimized Y4/M state switching, balancing the cable's flexibility and fire-resistant structural strength.

Armored Copper Strip Product Packaging and Storage

To facilitate handling and prevent product damage during transportation, finished strips are typically packaged in upright pallets, horizontal pallets, or upright wooden cases, with pearl cotton between the strips to prevent wear. The strips are then covered with stretch film and desiccant to protect against rain, dust, and moisture. To accommodate the cable industry's short lead times and urgent delivery needs, common product specifications are kept in stock to ensure timely delivery.

Why Choose Our Armored Copper Strips

FAQ

What are the main applications of armored copper strip?

It is primarily used in power cables, mineral insulated cables, and fire-resistant cables, providing strong protective functionality.

Why choose armored copper strip over other materials?

Armored copper strip offers superior conductivity and fire protection, while being lighter and more cost-effective compared to steel strips.

What grades of copper strip are available?

We offer various grades of armored copper strip such as H68, H65, T2, and TU, allowing customers to choose the suitable grade based on their requirements.

Why choose T2/TU oxygen-free copper material?

T2/TU materials have extremely high conductivity and oxidation resistance, making them the preferred choice for high-demand fire-resistant cables.

What are the differences between H68, H65, T2, and TU armored copper strips?

H68 and H65 are brass alloys (copper-zinc alloys) with excellent plasticity and strength. T2 is pure copper (≥99.90%) with high conductivity. TU2 is oxygen-free copper (≥99.95% Cu, ≤0.003% O) with no hydrogen embrittlement, making it ideal for high-reliability MI cables.

What do the states Y4 and M represent for armored copper strip?

Y4 represents 1/4 hard temper, providing moderate strength and good formability. M represents soft/annealed temper, offering excellent ductility suitable for complex forming processes. Both are designed for armor applications.

How does direct-use armored copper strip improve production efficiency?

Traditional processes require separate cutting, trimming, and handling steps. Our direct-use design eliminates these intermediate steps, reducing production time by up to 40% and minimizing quality variations.

What thickness and width ranges are available?

Standard thickness is from 0.05 to 2.0 mm, with widths ranging from 10 to 495 mm. Custom sizes are available upon request.

What types of cables use armored copper strip?

Mineral insulated (MI) cables, flexible fire-resistant cables (YTTW/BTLY series), and power cables requiring mechanical protection and shielding.
