稳相电缆的衰减稳定性提升的研究

Study on the Improvement of Attenuation Stability of Phase-Stable Cable

随着稳相电缆国产化的推进,其温度和机械相位稳定性的指标日渐优化。在产品使用的过程中,衰减稳定性指标也备受用户关注。对稳相电缆加工工艺进行分析,提出了提高产品衰减稳定性的一种结构方案,即在双层外导体中间增加一层隔离层。

With the advancement of localization,the stability index of temperature and mechanical phase of phase stable cable has been optimized day by day.In the process of product use,attenuation stability index is also concerned by users.In this paper,a structural scheme of attenuation stability is put forward by analyzing the process in the process of processing,and adds an isolation layer in the middle of the double layer outer conductor.
