The reporter learned from the 203th Institute of China Aerospace Science and Industry Corporation on the 18th that the Institute has recently developed a high-temperature, sealed RF coaxial cable assembly that has good sealing performance and is easy to assemble while resisting high-temperature environments. Reliable structure. The component will be used in aviation, aerospace, high-energy physics, quantum communications and other industries to provide protection for major national special projects.
The RF coaxial cable assembly is used to transmit RF and microwave signal energy and is a distributed parameter circuit. As a high-temperature series product for special cable assemblies, its demand is constantly increasing. In a single high-temperature and high-humidity environment, water vapor can easily enter the interior of the cable, so that the insulation of the cable and the pressure resistance index can be reduced, and the power capacity can be reduced. In severe cases, a short circuit may be caused and the system may be damaged. Therefore, its development has always been a problem in the industry.
At the end of 2016, a research institute of the Chinese Academy of Sciences proposed the use of high-temperature sealed cable assemblies. 203 through the technical research, to achieve the effective combination of high-temperature cable assemblies and sealed connectors, developed products can withstand high temperatures of 400 degrees Celsius and 95% of the humidity, changing the past, such products need to import the situation.
At present, the institute has developed a new high-temperature sealed adapter and cable assembly that can withstand temperatures up to 800 degrees Celsius. (Wu Yu Wang Huifeng reporter Fu Yifei)
