Copper Metal Strip for Cable Armor

What is armored copper strip

Copper tape is a core functional material in cable armor, providing both physical and electrical protection. It effectively resists mechanical wear, compression, and impact during cable operation and laying, blocks the intrusion of moisture and corrosive media, protects the cable core and insulation layer, and extends cable lifespan. Simultaneously, it serves as a grounding shield, diverting fault currents, suppressing electromagnetic interference, and ensuring stable and safe power transmission.

Compared to conventional armoring materials such as steel tape, the copper metal strip offers superior conductivity, ductility, and corrosion resistance. Its flexible texture and good fit make it suitable for various complex laying scenarios.

It provides better shielding and current dissipation, is less prone to corrosion failure, and has lower maintenance costs. It significantly improves the stability and durability of cable operation and is widely used in the armoring of medium and high voltage power cables and control cables.

Specification of copper strip for cable

Features of cable armoured copper strip

1. Worry-free Compliance and Acceptance: Strong conductive grounding performance, conforming to power regulations, eliminating rework and final payment disputes during acceptance.

2. Lower Maintenance Costs: Corrosion and oxidation resistant, suitable for various harsh working conditions, significantly reducing maintenance and replacement costs.

3. Less Construction Losses: Flexible and easy to bend, less prone to cracking and deformation during construction, effectively reducing scrap rates and rework costs.

4. Strong Anti-interference Performance: It shields against electromagnetic interference, ensuring stable equipment operation, suitable for high-end engineering conditions.

5. Energy-Saving, Safe, and Long-Lasting: No magnetic flux, no eddy current loss, low-temperature operation saves energy and is durable, extending the overall lifespan of the cable.

6. Higher Project Residual Value: High copper recycling value can offset procurement costs and increase overall project profits.

Packaging &Delivery

We use standardized export-grade moisture-proof and rust-proof packaging. Each roll is individually wrapped with moisture-proof paper and rust-proof film, and the outer layer is reinforced with rigid corner protectors and waterproof strapping to effectively prevent oxidation and scratches caused by moisture and salt spray during sea transport.

Products are neatly palletized and secured, conforming to container loading standards. The structure is stable and not easily shifted due to bumps. It is suitable for cross-border transportation methods such as sea and air freight, and can meet the customs clearance, overseas warehousing, and secondary transshipment requirements of various countries.
