The 10kV distribution network is an important part of the electric power system and the guarantee for the safe operation of the power grid and the improvement of electric power quality.In the current process of China's vigorous development of urbanization,the urban population has increased,the electricity load has increased,and the 10kV cable line has borne a greater pressure on power supply.However,in the process of urban distribution network construction,no sufficient attention has been paid to the design and construction of 10kV cable lines,resulting in many problems in the practical application process.Based on this condition,this paper elucidates the problems in the design of cable line,and further discusses the effective measures to solve the problems of line design,for reference only.
