Quality Control
Photovoltaic Solar H1Z2Z2-K Cable
Raw Material Test
Raw material testing for the Photovoltaic Solar H1Z2Z2-K Cable ensures premium quality from the outset. Tinned copper strands are inspected for conductivity, plating thickness, and adhesion using microscopy and elution tests. Halogen-free insulation and sheath compounds undergo melt flow index, density, and filler content analysis. Additives for UV stabilization are verified via FTIR spectroscopy. Samples are subjected to thermal aging, ozone resistance pre-checks, and elongation at break. Contamination screening prevents defects. The step-by-step process: incoming batch verification, sampling per EN 50618, physical/chemical property testing (tensile, hardness), environmental resistance simulation, and material approval. Only qualified raw materials advance, guaranteeing the Photovoltaic Solar H1Z2Z2-K Cable's long-term durability, safety, and performance in harsh solar environments.
Process inspection
During the manufacturing of the Photovoltaic Solar H1Z2Z2-K Cable, rigorous process inspection maintains consistency. Conductor stranding is monitored for compactness and tinning uniformity. Dual-layer extrusion of insulation and sheath is controlled for concentricity and thickness using online laser gauges. Electron-beam crosslinking degree is verified through hot set tests at multiple points. Surface quality and color coding are visually checked. Spark testing detects pinholes in real-time. Dimensional accuracy and ovality are measured continuously. Key steps: material dryness confirmation pre-extrusion, parameter stabilization (temperature, speed), intermediate sampling for gel fraction, defect marking/removal, and crosslinking dose logging. This in-line monitoring ensures the Photovoltaic Solar H1Z2Z2-K Cable achieves void-free insulation, precise geometry, and full compliance with EN 50618 standards.
Finished Product
The finished Photovoltaic Solar H1Z2Z2-K Cable undergoes comprehensive testing for certification. Routine tests include conductor resistance, high voltage withstand (6.5kV AC/15kV DC), and insulation thickness verification. Flame propagation (single/bundle), smoke density, and halogen acid gas emission confirm safety. Long-term DC voltage immersion, thermal endurance, and UV/weatherometer tests validate durability. Shrinkage, ozone, and mechanical impact checks follow EN 50618 protocols. The process steps: sample preparation, sequential voltage application with immersion, flame exposure timing, environmental chamber cycling, post-test mechanical/electrical measurement, and visual inspection. Additional verifications cover flexibility at low temperature and surface marking permanence. Only cables passing all criteria are approved, ensuring the Photovoltaic Solar H1Z2Z2-K Cable delivers reliable, safe performance in photovoltaic systems.
