XLPE PV Cables

XLPE photovoltaic cable uses radiation-crosslinked polyolefin as the insulation/jacket and is designed specifically for PV systems. Its key characteristics and applications are as follows. In terms of characteristics, **extremely strong weather resistance**: resistant to UV, salt spray and damp heat, passing 3000-hour aging tests with a service life of ≥ 25 years. Stable temperature performance (-40 °C to +90 °C, short-term tolerance to 125 °C, and 200 °C for 5 seconds under short-circuit conditions). Bend radius of only 4 times the outer diameter, volume resistivity ≥ 10¹⁴ Ω·cm, low smoke and halogen-free, flame retardant to UL94 V-0, and RoHS compliant. Applications focus on the PV chain: DC interconnection between modules and between modules and combiner boxes, and transmission from combiner boxes to inverters. It suits centralized power plants, distributed rooftop systems and PV-plus-storage systems, complies with IEC 62930 and UL4703 standards, and is the core cable for green energy transmission.
