2, the meaning of the specification method
Specifications using the number of cores, nominal cross-section and voltage rating
①Single-core branch cable specifications: the same circuit cable root * (1 * nominal cross-section), 0.6/1KV,
e.g.: 4 * (1 * 185)+1 * 95 0.6/1KV
② Multi-core stranded branch cable specifications: number of cables in the same circuit * nominal cross-section, 0.6/1KV,
such as: 4 * * 185 + 1 * 95 0.6/1KV
③ Multi-core with the same sheath branch cable specifications: cable core × nominal cross-section - T, such as: 4 × 25-T
