摘　　要：单/多芯预制分支电缆各具优势,单芯预制分支电缆在负荷计算电流较大时具有综合优势,多芯预制分支电缆对小负荷回路更为经济高效。选型时应根据工程实际情况,通过敷设条件、敷设方式、经济性等综合比较确定。Single / multi-core cables with pre-fabricated branched bear particular advantages. Single-core cables with pre-fabricated branched possess comprehensive advantages when the load current calculated is large, while multi-core cables with pre-fabricated branched are more economical and efficient for small load circuit. Type selection should be made on the basis of comparison among the specific project in terms of laying conditions, laying patterns, economy efficiency, etc.
