文昌发射场通信卫星塔架电缆设计方案及测试验证

Design and test verification of communication satellite tower cable for Wenchang launch site

海南文昌发射场的高温、高湿、盐雾等环境问题给通信卫星塔架电缆设计提出挑战。为此,文章在借鉴西昌发射场塔架电缆设计的基础上,提出塔架电缆由A1段、A2段和B段3个电缆分支组成;继而针对文昌发射场环境特点详述了塔架电缆在设计、铺设和使用方面关键点;最后对塔架电缆进行了测试验证,给出了测试内容和注意事项。所设计的塔架电缆已在3颗通信卫星正样星上得到验证,测试流程已基本固化,并形成了相应的操作性文件。

Environmental issues such as high temperature,high humidity and salt spray at Wenchang launch site in Hainan province pose challenges to the design of tower cables for communication satellites.Therefore,based on the design of tower cable at Xichang launch site,this paper proposed that the tower cable was composed of three cable branches:A1,A2,and B.Then,according to the environmental characteristics of Wenchang launch site,the key points in design,laying and use of tower cable were detailed.Finally,the tower cable was tested and verified,and the test contents and matters needing attention were given.The designed tower cable has been verified on three communication satellites,and the test process has been basically solidified with the corresponding operational documents formed.
