Cables Made Of Copper Clad Aluminum Wire And Pure Copper Cables


    When buying a Cat5e or Cat6 network cable, make sure you are comparing Apple. One of the most common strategies of "low-cost leaders" is to use aluminum instead of copper wire. Using poor-quality materials to transmit signals may cause network problems. Since there is no visual difference between CCA cables and pure copper cables, the problem is even more serious.
    Create copper clad aluminum cable
    In order to reduce costs, manufacturers have begun to use aluminum wires impregnated with a thin copper coating. This technology creates an aluminum core cable surrounded by a thin layer of copper. If you have purchased coaxial cables, you may have purchased copper-clad cables. If the center conductor is scratched, the gold and copper will peel off and expose the silver metal core. Consumers’ ignorance, smooth marketing and the same appearance have made copper clad aluminum jumpers more and more common in the market.

    Dangers of using CCA cables
    The performance and safety of CCA cables are completely different. In fact, aluminum network cables violate the TIA and IEC standards for Cat5e and Cat6 cables. Aluminum jumpers are usually marked as CCA or CCE (for copper-clad Ethernet), and their attenuation is higher than pure copper cables. This leads to greater data loss because the data packet must be retransmitted. The more data is retransmitted, the slower the network execution speed. In addition, every foot of cable you use makes these problems more complicated. The longer the cable, the worse the performance. Is the decline in network performance worth saving a few cents? The DC resistance of the Copper Clad Aluminum Wire cable is also 55% higher. This increases the energy transferred to the heat and reduces the power that can be transferred. This problem prevents them from being used for Power over Ethernet (PoE). These cut corners will also affect the installation personnel, because the aluminum wire will cause installation problems. Due to the low tensile strength, the aluminum cable may be damaged when pulled. A single wire may break, causing the cable to fail, or the entire cable may break. The bending radius of aluminum is also lower than that of pure copper cables. This means that you cannot bend too much before bending fails. In short, copper-clad cables are more fragile than pure copper cables.

    Problems in the real world
    If you think all these statistics are irrelevant in the real world, check out our burn test video posted above. When we heat up, the cable becomes brittle and breaks. The response of pure copper jumpers is completely different. Pay attention to how it maintains its shape. In fact, the jacket is more likely to catch fire before the conductor is damaged. Pure copper jumpers provide the best performance and security for your network. Don't risk your data and network security by choosing aluminum jumpers.
