Why can cables with different naming standards be used interchangeably in global projects?

Despite the different naming codes, the underlying technical benchmarks are often harmonized. High-quality aluminium cables are manufactured to comply with IEC 60502 or IEC 60228, which are the global foundations for conductor performance. As long as the rated voltage (e.g., 0.6/1kV), cross-sectional area (mm² or AWG/kcmil), and temperature rating (typically 90°C for XLPE) align with the project specifications, the cable is functionally equivalent regardless of whether it is labeled YJLV or NA2XY.
