Copper clad aluminum wire(CCA wire) is becoming a popular material to replace pure copper in the electrical and photovoltaic industries because of its cost advantage and functional performance.Economic superiorityanalyze:

1. Significant reduction in raw material costs

• Aluminum PriceLong-term stable and low-cost, about the price of copper 1/3 ～ 1/4.
• The copper-clad aluminum structure is only covered with copper on the surface.Save a lot of copper, which can reduce 30%～50% material cost.
• existPhotovoltaic welding ribbon, electronic cables, BMS busbars and other fields, replacing pure copper with copper-clad aluminum can bringSignificant cost reduction benefits.

2. Lightweight advantages reduce total system cost

• The density of aluminum is only about one tenth of that of copper. About 40%, the weight of copper-clad aluminum wire is greatly reduced, which is beneficial to:
  • transportation: Save logistics costs;
  • Install: Reduce labor intensity and improve efficiency;
  • Structural design: Reduce load-bearing structure requirements and save auxiliary materials.

3. Excellent conductivity per unit length/price ratio

• Although CCA conductivity is 60%–65% IACS, slightly lower than pure copper, but under the same cross-sectional area design, its "unit conductivity/cost" ratio is higher.
• Especially inHigh frequency (skin effect) or non-limiting current environmentIn the test, CCA performance is almost the same as pure copper.

4. System-level LCOE (cost per kilowatt-hour) reduction

• In photovoltaic systems, copper-clad aluminum ribbons are used instead of pure copper ribbons in modules, and the cost of ribbons per watt can be reduced by up to 0.001～0.003 yuan/W.
• Power generation efficiency loss is controlled in 0.5%～1.5% When the LCOE is within the range, the comprehensive calculation results show that: when the material cost drops significantly and the efficiency loss is slight,The overall electricity cost has dropped significantly.

5. High cost performance and adaptable to various applications

• In addition to the photovoltaic industry, CCA lines also demonstrate superior economic efficiency in the following areas:
  • Communication cable/coaxial cable: High-frequency signal transmission loss is small;
  • BMS system conductive sheet: Light weight and low cost;
  • New energy vehicle busbar: Replace copper in non-critical conductive parts;
  • Low voltage wiring harness/pin conductor: Meet conduction requirements and reduce vehicle weight.

in conclusion:

Copper clad aluminum wire has obvious economic advantages in terms of cost control, lightweight, unit conductivity cost performance, and total system cost. With the advancement of tape making and composite technology, its application penetration in photovoltaic, electric vehicles, energy storage and other industries will continue to rise in the future. For large-scale cost reduction scenarios, CCA wire is an extremely attractive solution.
