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

In the international market, EV cables follow structural or application-specific codes defined by IEC, EN, or UL standards. The Chinese system utilizes the GB (Guobiao) standard, characterized by specific pinyin initials.

Chinese System (GB/T 33594): Commonly uses models like EVR (Flexible conductor, PVC insulation), EVYR (PVC insulation/sheath), EV-V (PVC/PVC), and EV-Y (TPE/TPE).

European System (EN 50620 / IEC 62893): Models such as H05BZ5-F and H07BZ5-F are standard. The codes indicate harmonized standards (H), specific voltage ratings (05/07), and materials like TPU/PUR (B/Z5).

North American System (UL 62): Utilizes types such as EVE (Thermoplastic Elastomer), EVT (Thermoplastic PVC), and EVJ (Junior service, 300V).
