Why do Chinese cable type designations differ from IEC / European cable codes?

Chinese cable names are usually based on GB/T, JB/T, and national product standards. These names often describe the conductor, insulation, sheath material, fire performance, and application type in a Chinese coding system.
International projects commonly use IEC standards, European harmonised codes, EN standards, CPR reaction-to-fire classes, or local market specifications. These systems may describe the same cable performance using a different naming method.
For example, flexible rubber cables may be listed in China as YC or YZW type cables, while international buyers may be more familiar with H07RN-F. Flat lift or travelling cables may appear as TVVB / TVVBP in Chinese catalogues, while European catalogues may use H05VVH6-F or H07VVH6-F.
The name does not need to be identical as long as the cable meets the required rated voltage, temperature class, bending radius, flame retardant performance, LSZH performance, oil resistance, UV resistance, screening structure, and installation standard.
For international markets, the safest method is to provide a technical cross-reference table: Chinese standard reference, IEC / EN test method, cable construction, and project specification clause. This avoids the mistake of claiming that two names are automatically equal.
