Q. What is low-voltage photovoltaic cable?
A. It's a specialized cable designed for DC-side circuits in solar power systems, typically operating below 1.5kV DC, with UV-resistant and weatherproof properties4.
Q.What are the key features of PV cables?
A. Temperature resistance (-40°C to 120°C), UV/ozone protection, Halogen-free flame retardancy, Cross-linked polyethylene (XLPE) insulation
Q.Can regular cables replace PV cables?
A. No. Standard cables lack UV/weather resistance and may degrade rapidly in outdoor solar installations
Q.How to choose PV cable size?
A. Consider: Current rating (e.g., 4mm² for 30A), Voltage drop (<3% recommended), Ambient temperature
Q. What's the lifespan of PV cables?
A. Typically 25+ years when using certified products with proper installation
Q. Are PV cables fire-resistant?
A. Yes, premium PV cables use halogen-free materials to prevent toxic fumes during fires
Q.Can PV cables be buried directly?
A.Only if specifically rated as "direct burial" type; otherwise, use conduits
