YJV Cable: XLPE Insulation, Flame Retardancy, and Ampacity Derating
YJV cable—copper conductor, XLPE insulation, PVC sheath—is a low-voltage power cable widely used in commercial buildings, industrial plants, and infrastructure distribution. Its continuous operating temperature reaches 90°C, short-circuit withstand is 250°C for 5 seconds, and ampacity is 15%–30% higher than PVC-insulated cable of the same cross-section. But selection is not only about cross-section. Flame retardancy, […]
