Using aluminum core or copper core cable have been a topic of debate in cable selection.Urban distribution network is one of the important infrastructures for urban construction,with the development of urbanization in China, the demand of power cable of is growing and the proportion of power cable in the power grid construction cost is increasing significantly.Currently,the voice of using the aluminum alloy core cables raises again,because of excess capacity of China's electrolytic aluminum production and the improved mechanical properties of aluminum alloy core cables compared with pure aluminum alloy ones.The problems need to consider for the application of aluminum alloy cable is proposed by analyzing and comparing the differences in terms of structural size and electrical properties between the copper core and aluminum alloy cables.
