摘要
辐射型漏泄同轴电缆因其使用频带宽、覆盖范围广、传输距离长等特点获得了市场青睐,在高铁和地铁隧道中被广泛应用。本文通过对我实验室检测的具有规格为42的26根辐射型漏泄同轴电缆的纵向衰减、耦合损耗以及工程上普遍要求的系统损耗的检测结果进行分析,研究不同设计的漏缆的性能特点,并与现行标准YD/T 2491-2013《通信电缆物理发泡聚乙烯绝缘纵包铜带外导体辐射型漏泄同轴电缆》的要求进行比较,提出标准化建议。
Radiating leaky coaxial cable is favored by the market because of its wide frequency band,wide coverage and long transmission distance.It is widely used in high-speed railway and subway tunnel.In this paper,the longitudinal attenuation,coupling loss and system loss of 26 Radiating leaky coaxial cable with a specification of 42 tested by our laboratory are analyzed.Through studying the performance characteristics of leaky cables with different designs,and comparing with the requirements of current standard YD/T 2491-2013《communication cable-Radiating leaky coaxial cable with foamed polyethylene dielectric and longitudinal wrapped copper outer conductor》,standardization Suggestions are put forward.
