\u26a1 Overview of the Conductive Properties of Copper Clad Aluminum Strip<\/h3>

Copper clad aluminum strip is composed of high purity aluminum core and outer layer of pure copper.High conductivity<\/strong>With aluminumLightweight properties<\/strong>, its overall conductivity is better than pure aluminum and close to the level of copper.<\/p>

\u2705 Several key advantages of copper-clad aluminum conductivity<\/h3>
  1. Conductive effect close to that of pure copper<\/strong>: Because the current is concentrated on the surface of the conductor (skin effect), the copper layer can carry the main current.<\/li>\n\n
  2. Lightweight and low resistance<\/strong>: Copper-clad aluminum can provide a larger volume than copper at the same weight, thereby reducing the overall resistance per unit length.<\/li>\n\n
  3. Good welding performance<\/strong>: The surface layer is copper, which is suitable for conventional photovoltaic welding processes and does not require special adjustments.<\/li>\n\n
  4. Customizable copper layer thickness<\/strong>:likeRaytron<\/a>Companies such as AT&T can provide copper layer thickness \u22650.05mm to meet higher conductivity requirements.<\/li><\/ol>

    \ud83e\uddea Actual engineering data example<\/h3>
    • One 0.2\u00d75mm copper clad aluminum welding strip<\/strong>, copper layer thickness 0.05mm, overall conductivity can reach \u226562% IACS<\/strong>.<\/li>\n\n
    • If you want to replace 100% copper material, you only need to enlarge the cross-sectional area to About 1.5 times<\/strong>, you can achieveSame current carrying capacity and voltage drop performance<\/strong>.<\/li><\/ul>

      \u26a0 Precautions when using<\/h3>
      • A copper layer that is too thin will affect conductivity, so the uniformity of the copper layer must be strictly controlled during production.<\/li>\n\n
      • Using inferior CCA products (such as loose copper layer bonding, thin copper layer) will lead to problems such as increased resistance and heat accumulation.It is particularly important to choose high-quality manufacturers such as Ruichuang<\/strong>.<\/li><\/ul>","protected":false},"excerpt":{"rendered":"
