During the use of copper-clad aluminum strip, we should not only pay attention to its performance, but also pay special attention toSecurity issues<\/strong>, especially in power systems,Photovoltaic modules<\/a>When used in high reliability scenarios such as the following:Safety precautions<\/strong>:<\/p>

\u2705 Safety precautions for using copper-clad aluminum strip<\/h3>

1. Electrical safety - ensuring reliable electrical conduction<\/strong><\/h4>
  • Risk Points<\/strong>: When the copper layer is too thin or poorly bonded, the resistance becomes larger, it is easy to generate heat and even burn the equipment.<\/li>\n\n
  • Precautions<\/strong>:
    • Use high-quality products that meet standards (such as copper layer thickness \u2265 0.05mm, peel strength \u2265 10N\/cm).<\/li>\n\n
    • Perform continuity test and contact resistance test before welding.<\/li><\/ul><\/li><\/ul>

      2. Thermal safety - controlling soldering temperature and time<\/strong><\/h4>
      • Risk Points<\/strong>\uff1aAluminum conductors are easily oxidized. If the welding temperature is too high, it may cause thermal damage or loose solder joints.<\/li>\n\n
      • Precautions<\/strong>:
        • Strictly control the soldering temperature (recommended <300\u00b0C) and soldering time.<\/li>\n\n
        • Low temperature welding processes (such as hot air welding and ultrasonic welding) are preferred.<\/li><\/ul><\/li><\/ul>

          3. Mechanical safety - prevent cracks or breaks in the copper layer<\/strong><\/h4>
          • Risk Points<\/strong>: Repeated bending, pulling or excessive tension may cause copper layer peeling, broken tape and short circuit.<\/li>\n\n
          • Precautions<\/strong>:
            • Keep the bending radius \u226510D (D is the thickness of the strip) and avoid sharp angle operations.<\/li>\n\n
            • The production line tension should match the strip structure to avoid local stress.<\/li><\/ul><\/li><\/ul>

              4. Environmental safety - prevent oxidation corrosion<\/strong><\/h4>
              • Risk Points<\/strong>: The exposed aluminum core is easily corroded when exposed to moisture, salt spray, etc., which reduces its conductivity and increases the risk of fire.<\/li>\n\n
              • Precautions<\/strong>:
                • Keep the container dry and sealed before storage, and protect it from rain and moisture during transportation.<\/li>\n\n
                • After installation, use waterproof packaging materials (such as EVA, PET film) to isolate the air.<\/li><\/ul><\/li><\/ul>

                  5. Safe operation - prevent scratches or leakage<\/strong><\/h4>
                  • Risk Points<\/strong>: Surface scratches will expose the aluminum core, causing safety hazards such as leakage and poor grounding.<\/li>\n\n
                  • Precautions<\/strong>:
                    • Wear dust-free gloves during operation to avoid friction with hard objects.<\/li>\n\n
                    • Perform high voltage insulation test and visual inspection after installation.<\/li><\/ul><\/li><\/ul>

                      6. Compatibility safety - ensuring device compatibility<\/strong><\/h4>
                      • Risk Points<\/strong>: The default configuration of some welding equipment is suitable for pure copper strips. Direct replacement may easily cause welding abnormalities or poor contact.<\/li>\n\n
                      • Precautions<\/strong>:
                        • Debug the equipment before use to adapt the hardness and thickness of the copper-clad aluminum.<\/li>\n\n
                        • It can be used in batches only after integrity testing.<\/li><\/ul><\/li><\/ul>

                          \u2705 Recommended additional safety actions:<\/h3>
                          • Establish a "batch quality inspection mechanism" for copper-clad aluminum strips entering the factory, including three mandatory tests: copper layer thickness, bonding strength, and conductivity.<\/li>\n\n
                          • A "Manual of Precautions for Using Copper Clad Aluminum Strip" was set up at the project construction site and technical instructions were provided to the construction party.<\/li><\/ul>","protected":false},"excerpt":{"rendered":"
