摘　　要：指出预分支电缆在设计及使用中存在的几个问题:超大截面主干电缆分超小截面分支电缆应考虑截面跨度;预分支电缆多芯与单芯结构选型比较;大电流配电也可使用预分支电缆;不宜为降低成本而将普通电缆与预分支电缆组合使用。A number of issues about the design and application of cable with pre-fabricated branches are presented. For example, the span of cross section should be considered when the main cable with superlarge section is divided into branch cable with supersmall section; the multi-core structure and single-core structure of cable with pre-fabricated branches should be compared for selection; the cable with pre-fabricated branches can be also used for high-current power distribution; it is not recommended to use the cable with pre-fabricated branches together with the ordinary cable for the purpose of cost reduction.
