Suitable for useCopper clad aluminum stripThe location of the (CCA belt) is very wide, especially inPursuing lightweight, cost control, and requiring above-average electrical performanceIn photovoltaic and electrical systems, CCA tape has become an ideal alternative material. The following are some typical applicable environments and occasions:
? Suitable for use of copper clad aluminum strip:
1. Photovoltaic welding ribbon and internal connection of components
- Environmental conditions: well packaged, not exposed,Photovoltaic modulesThe internal working temperature is stable.
- Advantages: CCA welding ribbon has lower cost and lighter weight. After optimization, its conductivity is sufficient to meet the needs of photovoltaic current transmission. It is suitable for mainstream PERC, TOPCon, HJT and other battery components.
2. Indoor power distribution system
- Environmental conditions: stable temperature and humidity control, no corrosive gas.
- Applications: such as building wiring, household appliance connecting lines, internal wires of electric control cabinets, etc.
- Advantages: It is lighter than copper strip, easy to construct, and cost-effective.
3. Communication equipment and electronic product connection lines
- Application areas: smart home appliances, weak current systems, signal transmission cables, etc.
- Features: In applications that require stable signal transmission rather than extremely high current, the high cost-performance of CCA cables shows obvious advantages.
4. Energy storage systems for the new energy industry (BMS connection)
- Environment: Closed box, good anti-corrosion measures.
- Application: Connecting pieces and bus bars between energy storage battery modules.
- Advantages: Copper-clad aluminum strip can effectively reduce the overall system weight and cost, adapting to the lightweight trend of new energy.
5. LED lighting system
- Features: small current and high requirements on conductor flexibility.
- Advantages: Copper-clad aluminum material has good flexibility and is much cheaper than pure copper, making it suitable for internal wiring of LED lamps.
6. Large-volume export component manufacturing
- Region: Markets with higher requirements for cost-effectiveness, such as India, Southeast Asia, Latin America, etc.
- Reason: Without affecting the product's service life and electrical performance, copper-clad aluminum strip can significantly reduce costs and is one of the mainstream choices.
Summary: Environmental characteristics suitable for copper-clad aluminum strip
