Q: What are the conductor and insulation materials? How is solar photovoltaic cable different from regular cable?
A: Yongshang solar photovoltaic cables use adouble-insulation structuredesigned for harsh outdoor PV environments:
• Conductor: 99.99% oxygen-free tinned copper, multi-strand flexible, tin plating for anti-oxidation and corrosion resistance;
• Insulation: XLPE / XLPO (cross-linked polyolefin), high temperature and voltage resistant;
• Sheath: XLPO,UV-resistant, ozone-resistant, acid/alkali/salt resistant, flame retardant;
• Voltage rating: AC 0.6/1kV, DC 1.8kV;
• Temperature range: -40°C ~ +90°C (short-term up to +120°C).
Regular PVC cables have single-layer insulation, no UV or high-temperature resistance, and will crack after 1-2 years outdoors. Theymust never replace solar cablefor DC inter-panel connections.
