  • Product Features:
    The conductor consists of 56 precision-stranded tinned copper wires (0.28mm diameter), with available outer diameters of 5.7mm or 6.1mm. It offers superior ozone and hydrolysis resistance and has passed rigorous CPR (Construction Products Regulation) fire safety classification tests.

    Applications:
    Main trunk cabling for large-scale ground-mounted power plants and industrial rooftop arrays, as well as primary DC input paths for high-performance string inverters.

    Common Issues and Solutions:
    Issue: Excessive heat generation at the terminal crimp connection.
    Solution: Use the correctly specified MC4 connector and a high-precision crimping tool to ensure contact resistance remains below 0.5mΩ.
    Important Note: For grid-connection tenders in the EU, a Declaration of Performance (DoP) document must be provided, and the XLPO marking on the cable surface must be clear and compliant.
