摘　　要：微波电缆在卫星上得到大量应用,其作用是传输微波信号,与以往采用半刚电缆固定连接方式不同,某卫星需要通过柔性活动微波电缆网来连接运动天线和通信舱内设备。由于此种电缆属单点失效项目,且柔性活动微波电缆为首次使用,需要解决好选型及可靠性保证工作,其工程实践活动对类似电缆的选型和可靠性保证工作具有借鉴作用。Microwave cable is widely used on satellites to transmit microwave signal. Different from the previous fixed connection of semi-rigid cable,flexible microwave cable network is employed on one satellite to connect moving antennas and devices outside the capsule. Problems such as reliability guarantee and product selection need to be properly tackled because flexible microwave cable is used on satellite the first time and this kind of cable is sigle point failure item. This engineering nractice will ulav a reference role in selection of similar cable and reliability guarantee.

关 键 词：活动微波电缆 可靠性保证
