摘　　要：耐动态切通能力是航空用聚四氟乙烯/聚酰亚胺复合薄膜绝缘电线的一项重要技术指标,该试验可以模拟不同温度环境下,绝缘电线承受机械应力时可能会出现的损坏。介绍了航空绝缘电线耐动态切通的试验方法,对试验原理进行了描述,并对导体材料、绝缘结构、绝缘厚度以及温度等电线耐动态切通能力的影响因素进行了分析。The property of resistance to dynamic cut-through is one of the most important properties of polytetrafluoroethylene / polyimide Insulated wire,it can simulate the damage might happen when the insulated wire meets penetration of a cutting surface at different temperature environments. This paper presents the dynamic cut-through test of wire,describes the mechanism of the test,and analysis the influencing factors of the test result from the factors such as material of conductor,structure of insulation,thickness of insulation and test temperature,etc.
