低压动力电缆截面的选型与经济性分析

Selection and Economic Analysis of the Cross-section of Low-voltage Power Cable

工程设计人员在进行低压动力电缆截面选型时,往往从技术角度进行电缆截面选型,这的确能做到安全可靠、技术先进,但却忽略了电缆截面在运行期的经济性。结合工程案例,研究并介绍了选择低压动力电缆截面的具体方法,并从技术性及经济性两个角度对总投资费用进行比较和分析,同时分析了不同参数的变化对电缆总投资经济性的影响。

When engineering designers select low-voltage power cable cross-sections,they often select cable cross-sections from a technical point of view.This is indeed safe,reliable,and technologically advanced,but it ignores the economics of cable cross-sections during operation.Combined with engineering cases,the main research and explanation of the specific method of selecting the cross section of low-voltage power cable,and from the technical and economic perspectives of the total investment cost comparison and analysis,at the same time analyze the changes in different parameters on the total cable investment economic.
