SOWELLSOLAR Launches 70% Copper Conductor PV Cable Balancing Cost and Performance
In March 2026, SOWELLSOLAR (a brand under Xiaowei Electric) introduced an innovative photovoltaic cable known as the 70% copper conductor PV cable (model: SE-TCA).
Innovative Conductor Material:
The SE-TCA conductor is manufactured from a copper alloy containing 70% copper, significantly reducing the amount of pure copper traditionally required in PV cables. Despite the reduced copper content, the cable is engineered to maintain stable electrical performance and mechanical reliability in demanding outdoor environments.
Key Advantages:
Achieves the same DC resistance as pure copper cables with the same nominal cross-sectional area (e.g., 4 mm²)
System designers can directly replace conventional copper PV cables without increasing cable size
Mitigates the impact of copper price volatility on project costs
Successfully passed stringent testing under EN 50618 and IEC 62930
Obtained multiple TÜV certifications
Application Potential: The SE-TCA is expected to find applications in large-scale ground-mounted solar plants as well as distributed photovoltaic systems, offering a new option that balances electrical performance, long-term reliability, and economic efficiency.
