Meaning of cable specification representation

Specifications are expressed in terms of number of cores, nominal cross-section, and voltage level,  ① Specification representation of single core branch cable: number of cables in the same circuit * (1 * nominal cross-section), 0.6/1KV,  For example: 4 * (1 * 185)+1 * 95 0.6/1KV,  ② Specification representation of multi-core stranded branch cable: number of cables in the same circuit * nominal cross-section, 0.6/1KV,  For example: 4 * * 185+1 * 95 0.6/1KV,  ③ Specification representation of multi-core and sheathed branch cables: number of cable cores × Nominal section - T, such as: 4 × 25-T
