摘　　要：就配电线路布线系统中电力电缆经济电流截面计算式中参数的确定,简述须考虑的因素和各相关专业需要配合提供的资料数据;分析核算误差对核算结果的影响并提出设计使用中的建议;认为电缆运行情况与设计预期是否一致是能否取得最经济效果的关键;建议有条件时对能够准确预期运行状况的配电线路布线注意电缆经济电流截面的应用。In order to determine the parameters in the equation of economic section of power cable in the distribution system, the paper gives a brief account on considerations and supporting data provided by relevant disciplines, analyzes the impact of calculation error on calculation results and proposes recommendations for design and application. It is believed that the consistency between the operational state of power cable and design intent is critical to the recognition of the most economic effect. And it is suggested that, the selection on economic section of power cable shall be considered in the distribution system that is capable of making accurate predictions on the operational state when available.
