The PV1-F photovoltaic cable uses multiple strands of tin-plated copper wire twisted together as the conductor, enhancing the anti-oxidation and anti-corrosion performance. The conductor is wrapped with a halogen-free flame-retardant polyolefin insulation layer, which features weather resistance, UV resistance and flame retardancy. The operating temperature range is from -40℃ to 90℃ (up to 180℃ in a short circuit). The outermost layer also adopts a halogen-free flame-retardant polyolefin sheath, enhancing mechanical protection capabilities and ensuring stable power transmission in the photovoltaic system.
