摘　　要：综合分析作为电力电缆主要电气参数的导电线芯有效电阻的实用概念。电阻有效值的热效应会影响电缆传输容量、减少运行载流量。其中工频交流下导电线芯大截面的集肤效应、邻近效应是有效电阻增大的主要原因。This text analyzes the effective resistance of conductor wire core, one of the main electric parameter of power cable.The heating effects of the effective value of resistance will affect transmission capability of power cable and reduce carrying capacity of running current,among which skin effect and close effect of large-section conductor wire core under wore-frequency alternating current are main causes of the effective resistance increment.
