雪的密度 meaning in Chinese

snow density

The paper studied withstand voltage level , influence factors , breakdown process and breakdown mechanism of covered with snow or ice through some theory calculation results , many test data and phenomena . the paper got the conclusions that withstand voltage strength of insulator covered with snow or ice descended largely , and the amount of ice or snow build - up , number of flashover , string length , environment temperature and leak current etc had obvious effects on flashover voltage values of insulators
通过大量的试验数据和现象研究冰雪条件下绝缘子的耐压水平、影响因素及其击穿机理，如串长的影响、环境温度、绝缘子形状及冰的干湿程度、闪络次数、冠雪量和积冰量的影响、雪的密度、气压和湿度的影响等，并对试验结果与理论分析结果进行了对比，分析其是否一致。
