| Mechanical Strength | Easily breaks during installation |
Flexible, less prone to breaking |
Flexible and durable, easy installation |
| Oxidation Resistance / Lifespan | Aluminum core oxidizes quickly, short lifespan |
Alloy resists oxidation, longer lifespan |
Oxidation resistant, 10+ years lifespan |
| Transmission Distance | < 70m (performance drops sharply) | ≈ 90m (stable performance) | > 100m (meets standards) |
| Cost Effectiveness | Low initial cost, high total cost | Optimal price/performance ratio | High initial cost, high long-term value |
| Application Scenarios | Temporary wiring, non-critical applications | Small/medium projects, budget constraints | Mission-critical, high-end applications |
High resistance causes severe heating during POE power supply, potentially leading to device reboots, performance degradation, and even fire hazards and equipment damage risks.
Severe signal attenuation causes performance to drop sharply beyond 70 meters, failing to meet the standard 100-meter transmission requirement, resulting in unstable networks.
Aluminum core is brittle with poor ductility, easily breaking during conduit pulling, leading to high installation failure rates and difficult troubleshooting.
Aluminum core oxidizes quickly when exposed to air, increasing resistance and further degrading performance, with extremely short lifespan (1-2 years) in humid environments.
Poor contact with RJ45 connectors and patch panels leads to intermittent connection problems, making faults difficult to troubleshoot.
High failure rates result in continuous after-sales pressure, with repair and replacement costs ultimately far exceeding initial savings.
Our 30% copper content alloy copper network cable achieves a perfect balance between cost and performance, solving all the pain points of CCA:
Price only 30-40% higher than CCA, but performance improvement over 100%
Transmission performance reaches 85-90% of pure copper, meeting most application needs
Stable POE power supply, no overheating risk, long service life
