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

In the international market, marine cables follow structural codes based on IEC 60092 standards or regional norms like NEK 606 (Norway) or BS 6883 (UK). The Chinese system utilizes the GB (Guobiao) standard, which uses Pinyin initials to denote marine application and construction.

Chinese System (GB/T): Common models use the prefix CB or CH. Examples include CHV (PVC insulation/sheath), CHJ (XLPE insulation), and CHJP86 (XLPE insulation, tinned copper braid, armored).

International System: Focuses on standard-specific codes such as MPRX (XLPE insulation), MGCH (Halogen-free), or TCU/XLPE/OS/LSZH.

Common Comparison: A Chinese CHJ series is functionally equivalent to an international MPRX or MRE-2X cable, provided they share the same core specifications.
