电子工业部第二十三研究所研制成功的微波低损耗电缆有二种规格:SUY-50-5.3-3型和SUY-50-9-3型。它们具有相同结构的形式,即镀银圆铜线内导体、聚四氟乙烯穿孔带绕包绝缘、绉纹铜管外导体和聚乙烯护套。这二种电缆可在通信、电子对抗、跟踪、警戒等系统中用作各种无线电设备的传输线或延迟线,具有频带宽、衰减小,均匀性好、能承受一定功率等特点。主要性能如下表所示:
The twenty-third Institute of the Ministry of Electronics Industry has successfully developed two types of microwave low loss cables: SUY-50-5.3-3 type and SUY-50-9-3 type. They have the same structure in the form of silver-plated copper inner conductors, PTFE perforated tape wrap insulation, crepe copper outer conductors, and polyethylene sheathing. These two kinds of cables can be used as transmission lines or delay lines of various radio equipments in the systems of communication, electronic countermeasure, tracking and alerting, etc. They have the advantages of wide frequency band, small attenuation, good uniformity and able to bear certain power. The main performance as shown in the following table:
