During the use of copper-clad aluminum strip, we should not only pay attention to its performance, but also pay special attention toSecurity issues, especially in power systems,Photovoltaic modulesWhen used in high reliability scenarios such as the following:Safety precautions:
? Safety precautions for using copper-clad aluminum strip
1. Electrical safety - ensuring reliable electrical conduction
- Risk Points: 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.
- Precautions:
- Use high-quality products that meet standards (such as copper layer thickness ≥ 0.05mm, peel strength ≥ 10N/cm).
- Perform continuity test and contact resistance test before welding.
2. Thermal safety - controlling soldering temperature and time
- Risk Points：Aluminum conductors are easily oxidized. If the welding temperature is too high, it may cause thermal damage or loose solder joints.
- Precautions:
- Strictly control the soldering temperature (recommended <300°C) and soldering time.
- Low temperature welding processes (such as hot air welding and ultrasonic welding) are preferred.
3. Mechanical safety - prevent cracks or breaks in the copper layer
- Risk Points: Repeated bending, pulling or excessive tension may cause copper layer peeling, broken tape and short circuit.
- Precautions:
- Keep the bending radius ≥10D (D is the thickness of the strip) and avoid sharp angle operations.
- The production line tension should match the strip structure to avoid local stress.
4. Environmental safety - prevent oxidation corrosion
- Risk Points: The exposed aluminum core is easily corroded when exposed to moisture, salt spray, etc., which reduces its conductivity and increases the risk of fire.
- Precautions:
- Keep the container dry and sealed before storage, and protect it from rain and moisture during transportation.
- After installation, use waterproof packaging materials (such as EVA, PET film) to isolate the air.
5. Safe operation - prevent scratches or leakage
- Risk Points: Surface scratches will expose the aluminum core, causing safety hazards such as leakage and poor grounding.
- Precautions:
- Wear dust-free gloves during operation to avoid friction with hard objects.
- Perform high voltage insulation test and visual inspection after installation.
6. Compatibility safety - ensuring device compatibility
- Risk Points: The default configuration of some welding equipment is suitable for pure copper strips. Direct replacement may easily cause welding abnormalities or poor contact.
- Precautions:
- Debug the equipment before use to adapt the hardness and thickness of the copper-clad aluminum.
- It can be used in batches only after integrity testing.
? Recommended additional safety actions:
- 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.
- 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.
