摘　　要：高性能数据传输线在大型设备数据传输及仪器环境试验监测中具有重要作用,传输线绝缘层开裂将导致内部导体裸露在外部环境中,造成导体腐蚀,传输线之间短路烧毁等失效现象,甚至造成重大事故。结合温度传感器导线绝缘层开裂案例,分析了聚四氟乙烯导线绝缘层开裂原因,并提出了针对性的改善措施,为预防聚四氟乙烯导线绝缘层开裂提供了借鉴和应用范例。High-performance data transmission lines play an important role in large-scale equipment data transmission and instrument environmental test monitoring. Cracking of the transmission line insulation will cause the exposed internal conductors to be corroded in the external environment, causing short-circuits between transmission lines and burning and causing major accidents. Combining the case of temperature sensor wire insulation cracking, the reasons for the cracking of the PTFE wire insulation layer are analyzed,and targeted improvement measures are proposed, which provide a reference and application example for preventing the cracking of the PTFE wire insulation layer.
