What are the primary differences between Chinese (GB) and International cable naming conventions?

In the international market, naming conventions typically follow structural or material-based coding (such as the VDE or harmonized <HAR> systems), whereas the Chinese system uses the GB (Guobiao) standard based on Pinyin initials.

Chinese System (GB/T): Uses letters like K (Control), V (PVC insulation/sheath), P (Braided shield), and R (Flexible conductor). For example, KVVP represents a PVC-insulated, PVC-sheathed, braided-screen control cable.

International System (IEC/VDE): Uses codes like Y (PVC), SL (Control/Static), C (Copper screen), and S (Steel wire braid). A common equivalent to KVVP would be YSLCY or simply CY cable.
