How do Chinese (GB) and International naming conventions for Medium Voltage cables differ?

In the international market, MV cables follow structural codes based on the insulation and shielding layers (e.g., European VDE or IEC systems). The Chinese system uses the GB (Guobiao) standard, which utilizes Pinyin initials to define the material layers.

Chinese System (GB/T 12706): Common models include YJV (XLPE insulation, PVC sheath), YJV22 (XLPE insulation, steel tape armored, PVC sheath), and YJLV (Aluminium conductor version).

International System: Common designations include NA2XSY (Aluminium, XLPE, Copper Screen, PVC), N2XSEY (Copper, XLPE, Individual Screen, PVC), or AWA/SWA (Aluminium/Steel Wire Armored) for British Standards (BS 6622).
