Research on dc Resistance Detection of wire and Cable Conductor and its Improvement Method

导体电阻是电线电缆中非常重要的技术参数。依据G/T3956-2008相关标准,电能在线路中的损耗与导体电阻成平方级反比。因此直流电阻的具体数据直接影响着电线电缆的供电安全性能与效率,本文详细说明了不同情况对电线电缆导体直流电阻检测过程中的影响,同时对如何改进检测数据精确度的方法做了探究。

Conductor resistance is a very important technical parameter in wire and cable.According to the relevant standards of G/T3956-2008,the loss of electrical energy in the line is inversely proportional to the square of the conductor resistance.Therefore,the specific data of DC resistance directly affects the safety and efficiency of wire and cable for power supply performance.In this paper,the effects of different conditions on the DC resistance detection process of wire and cable conductors are described in detail.
