Samples undergo accelerated UV aging, ozone resistance, and environmental stress cracking tests. The step-by-step process includes incoming batch verification, random sampling, chemical composition analysis via spectrometry, mechanical property testing before and after aging, UV and weather resistance pre-checks, and final material approval decision. Only qualified materials are released, guaranteeing the H1Z2Z2-K Solar Cable Tinned Stranded Copper achieves excellent conductivity, insulation integrity, superior weather resistance, and long-term reliability in solar PV applications.
Process inspection
During manufacturing of the H1Z2Z2-K Solar Cable Tinned Stranded Copper, process inspection maintains strict quality control. Copper conductor stranding and tinning are monitored for uniformity and coating thickness. XLPO insulation extrusion controls thickness, concentricity, and bonding with online capacitance and X-ray systems. Sheath extrusion ensures uniform covering and surface smoothness. Real-time spark testing detects defects. Key steps include material pre-drying confirmation, extrusion parameter logging (temperature, speed, tension), intermediate hot set tests for crosslinking degree, defect detection with immediate correction, and controlled cooling. This multi-stage oversight guarantees the H1Z2Z2-K Solar Cable Tinned Stranded Copper achieves void-free insulation, precise construction, and full TÜV/EN 50618 compliance throughout production.
Finished Product
The finished H1Z2Z2-K Solar Cable Tinned Stranded Copper undergoes comprehensive testing. Routine tests include conductor resistance, AC/DC voltage withstand, insulation thickness verification, and spark testing. Mechanical tests cover elongation, cold bend, and tensile strength. Weathering via UV aging, ozone resistance, and heat distortion is assessed. The process steps include sample preparation, gradual voltage ramp-up and hold period, mechanical load application, environmental conditioning (UV/heat), post-test electrical and mechanical re-measurement, and detailed visual inspection. Additional checks cover shrinkage, marking durability, and long-term aging performance. Only cables passing all criteria are approved, confirming the H1Z2Z2-K Solar Cable Tinned Stranded Copper’s superior electrical safety, mechanical robustness, and suitability for solar photovoltaic systems.
