Update and analysis of economic current density for medium and low voltage copper cables

CHEN Ming-hui1,HE Xiang-zhen1,ZHOU Sheng2,WANG Da-gang2,WANG Zhi-qiang2,WEN Fu-shuan1(1.College of Electric Power,South China University of Technology,Guangzhou 510640,China;2.International Copper Association Ltd.China,Beijing 100045,China)  
The ever-increasing copper price in the past several years has led to a significant increase of the cost of copper cables,and the economic section has hence decreased.Thus,whether the economic section obtained from past data could still meet the current carrying capacity is becoming a matter to be investigated.The recent cost data associated with medium and low voltage copper cables are collected and handled,and then as the basis for updating the economic current density data in this paper.To facilitate the use of the economic current density data,a cable type parameter is introduced.In addition,the stability and accuracy of the updated economic current density data are verified by using actual data.
