| 摘 要： | 根据特高频信号传输衰减原理进行衰减-吸潮性试验。重点讨论了发泡绝缘线芯上发泡质量对防潮性的影响,并对影响发泡质量的多种因素进行了分析,并提出了绝缘线芯的防潮措施。试验给出最佳发泡挤出工艺A2B2C2D2,所得发泡体泡孔细密、分布均匀、互相闭合不相通。据此发泡工艺和引述的三项防水防潮措施生产的同轴电缆,经288 h的湿热试验,其信号衰减增量都小于1%。

| Abstract: | Attenuation-moisture test was carded out based on the principle of UHF signal transmission attenuation. Especially the effect of the foaming quality of insulated conductors on moisture resistance was discussed. The factors affecting the foaming quality were identified and counter measures for moisture resistance of insulated conductors were suggested. An optimized foaming process A2 B2 C2 D2 was obtained by experiment, by which fine, closed and evenly distributed foams are produced. The coaxial cables produced by this process with a moisture preventive measure applied have an additional signal attenuation of less than 1% after a damp heat test for 288 h. |
