How do Chinese (GB) and International naming conventions for aluminium cables differ?
In the international market, naming conventions follow structural codes (like the European VDE/IEC system) or application-based designations (like the North American ASTM system). The Chinese system uses the GB (Guobiao) standard, typically identified by the letter “L” for Aluminum (้).
Chinese System (GB/T): Common models include YJLV (XLPE insulation, PVC sheath), VLV (PVC insulation/sheath), and BLV (PVC insulated wire). The “L” signifies the aluminium conductor.
International/European System (IEC): Uses codes like NAYY (PVC/PVC), NA2XY (XLPE/PVC), or NA2X2Y (XLPE/PE). The “NA” prefix denotes an aluminium conductor according to VDE standards.
North American System (ASTM): Identified by alloy series and insulation types like XHHW-2, THHN/THWN-2, or specific trade names for AA-8000 series alloys.
