Copperweld Sunray

/

Sunray is a direct replacement of PhotoVoltaic (PV) cable, the interconnecting cable used between solar panels in a solar farm. Sunray is the most energy-efficient and cost-efficient photovoltaic (PV) wire on the market. These premium CCA conductors offer 3% greater efficiency than standard cables.

  • Product range: AWG #10 / AWG #8 / AWG #6

  • Voltage (Max): 2 kV

  • Construction: 7-strand CCA with XLPE

  • ASTM B-566 (standard specification for copper-clad aluminum wire), UL 44 (standard for safety thermoset-insulated wires and cables), UL 4703 (standard for safety photovoltaic wire)

  • Sunlight Resistant, FV-1 vertical flame rated, Gasoline and Oil Resistant II

  • -40°C to 90°C Wet and Dry Rated

  • Direct Burial Rated

  • ICEA S-95-658/NEMA WC-70

Customers using Copperweld Sunray CCA wire (UL 4703-listed since 2020) for solar power generation experience a more than 3% increase in efficiency compared to those using copper, accumulating to significant cost savings year after year and positively impacting the return on investment for any solar project.

Copperweld achieves this by metallurgically bonding oxygen-free copper to an AA 8000 Series aluminum core, which allows for copper-to-copper connections in the field or in your ultrasonic pre-assembly facility.
