电力电缆导体直流电阻不合格问题分析

Analysis of Unqualified DC Resistance of Power cable Conductor

导体直流电阻是电力电缆产品质量的关键性能指标,阻值高低直接关系着输电线路的安全稳定运行。文章从实验室检测的角度对电力电缆直流电阻检测不合格的原因进行系统分析,并就如何进行质量管控,提高检测的准确性做了探讨。

Conductor DC resistance is the key performance index of power cable product quality,and the resistance value is directly related to the safe and stable operation of transmission lines.This paper systematically analyzes the causes of unqualified DC resistance of power cables from the perspective of laboratory testing,and discusses how to conduct quality control and improve the accuracy of testing.
