Research on deviation calculation and quality control of key performance indicators for medium-voltage power cables

In this study, a systematic quality inspection was first conducted on 200 medium-voltage power cable samples produced by different manufacturers. A calculation method for relative difference (∆d) was proposed to quantitatively analyze the compliance of cable performance indicators with standard technical requirements. Based on these findings, a systematic computational analysis of the identified anomalies was conducted, and corresponding optimization solutions were proposed. The results of this study can provide a quantitative basis and technical references for quality control and performance optimization of current medium-voltage power cables.
