摘要

根据近些年行业的报道,运行多年的高压电缆,缓冲层及绝缘屏蔽表面与金属护套波谷接触部位存在"烧蚀"和"白斑"的现象,对高压电缆用缓冲层材料及几种典型高压电缆缓冲层结构的特性进行了研究,通过模拟试验再现"烧蚀"和"白斑"的形成,并提出了改进建议。
        According to the industry reports in recent years, there are "Ablative materials" and "white spots" in buffer layers and the place where insulating shielding surfaces touch the metal sheathed troughs of high voltage cable after using many years. Buffer materials for high voltage cable and the characteristics of several typical buffer layer structure in high voltage cable were researched, "ablative materials" and "white spots" were reproduced by simulation test. Improved suggestions were provided by this paper.
