摘　　要：低压电缆截面可从技术和经济条件进行选型。以经济截面选型为理论基础,论述了按经济电流选择低压电缆截面的经济电流方法,并结合工程案例,剖析了有关参数变化对电缆经济电流选型中运行经济效益的影响。有利于工程技术人员根据工程项目的特点,合理选择相关参数,选取相对最优的经济电缆截面,从而可起到节约资源、保护环境的作用。Low voltage cable cross-section can be sized from a technical and economic conditions.In this paper, the theoretical basis for the selection of the economic section discusses the current selection according to the economic section of the economic current low voltage cable method, combined with the project, the economic analysis of the impact on the current selection in the cable run econom-ic benefits related parameters.In favor of engineering and technical personnel in accordance with the characteristics of the project, a rea-sonable choice of parameters, select the cable cross-section relative to the optimal economic and thus can play conserve resources and protect the role of the environment.
