Premium Bare Copper Network Cabling Solutions for Data Center Infrastructure

Excellence Wire Ind. Co., Ltd. specializes in manufacturing UL/ETL certified bare copper ethernet cables and RJ45 connectors that exceed TIA standards and deliver superior transmission reliability compared to CCA alternatives.

Benefit of Using Bare Copper Wires

All of EXW Patch Cords Use Bare Copper Wires

All of EXW patch cords use pure bare copper wires. EXW patch cords do not use CCA (copper clad aluminum) wires nor do we recommend using patch cords made of CCA wires. In fact, aluminum network cables violate the TIA standard for Cat.5e, Cat.6, Cat.6A, and Cat.8 cables.

We insist on manufacturing reliable ethernet cables with bare copper that pass the Fluke component or channel test. Cat.6A S/FTP 26 AWG Patch Cord passed the component test. Cat.8 S/FTP 22 AWG Solid Cable and Cat.8 S/FTP 26 AWG Stranded Patch Cord passed the channel test.

What Makes Bare Copper Wires Better?

Compared to pure bare copper wires, copper clad aluminum (CCA) wires are cheaper and weigh less. The tensile strength of a CCA wire is weaker than that of a pure copper wire, so CCA wires are more vulnerable, which might cause transmission failure. Some CCA wires claim to have the same conductivity with “slightly” higher resistance. However, there will be data lost in transmission. It is likely to slow down the transmission speed and unlikely to maintain the transmission speed requirements in the long run. As an increasing amount of data is transmitted over a single Internet cable and PoE, these problems eventually emerge and accumulate over time.

We Use Bare Copper Wires in All of Our RJ45 LAN Cables and Patch Cords

Bare copper wires are used in all of our patch cords to guarantee the quality of data transmission. We do not use any CCA, CCS or other materials. There are several reasons that we insist in using bare copper wires and provide the best kind of patch cords to our customers.

4 Benefits of Bare Copper Wires

  • Bare copper wires are more resistant to corrosion. It will give a longer shelf life.
  • It also has a high melting point and high heat resistance, which is beneficial in extreme heat and humid conditions.
  • Most of the electrical appliances use bare copper because it is durable and long-lasting.
  • It can be used in a variety of industries like manufacturing, electrical, marine and telecom companies.

How can you ensure your data center cabling infrastructure meets stringent performance standards while avoiding costly transmission failures?

EXW's bare copper RJ45 patch cords and structured cabling are Fluke tested and UL/ETL certified to exceed TIA standards. Unlike CCA alternatives that degrade over time, our pure bare copper construction guarantees superior tensile strength, corrosion resistance, and consistent transmission speeds—even under high data volume and PoE loads. Specify EXW bare copper solutions to eliminate transmission vulnerabilities and future-proof your data center infrastructure.

EXW's commitment to bare copper manufacturing reflects industry best practices for mission-critical data center and telecommunications infrastructure. Unlike CCA wires that claim equivalent conductivity while introducing higher resistance and eventual data loss, EXW's bare copper solutions maintain consistent transmission speeds and reliability as data volume and Power over Ethernet (PoE) demands increase. With UL/ETL certifications, FORCE, GHMT, REACH, and RoHS compliance, EXW patch cords and structured cabling systems provide the certified quality assurance that data centers, network integrators, and telecommunications providers require. Contact EXW today to specify bare copper cabling solutions that eliminate transmission vulnerabilities and ensure long-term network infrastructure performance.
