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.
