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

In the international market, rubber cables generally follow the European Harmonized <HAR> system or application-based codes. The Chinese system utilizes the GB (Guobiao) standard, which uses Pinyin initials to denote cable structure and material.

Chinese System (GB/T 5013): Common models include YC (Heavy-duty), YZ (Medium-duty), and YQ (Light-duty). The prefix “Y” stands for Yajiao (Rubber). YH is specifically for welding cables.

International System: Focuses on harmonized codes such as H07RN-F (Heavy-duty, oil-resistant), H05RR-F (Light-duty), and H01N2-D (Welding cable).

Materials: Chinese “Rubber” usually refers to natural or styrene-butadiene rubber, while international “RN” (Chloroprene/Neoprene) and “BN” (EPR) provide higher chemical and thermal resistance.
