China Aerospace Science and Technology: New Temperature Sealed Coaxial Cable Assembly

On September 25, 203 of the Second Academy of China Aerospace Science and Industry Corporation announced that it had successfully developed a high temperature sealed coaxial Cable Assembly. The product has good sealing performance while being resistant to high temperature environment, simple assembly and reliable structure, and will be applied to aviation, aerospace, high energy physics, quantum communication industry.

It is understood that high temperature and high humidity coaxial cable assemblies have always been a problem in the industry. Cable assemblies used in high temperature and high humidity environments not only need to withstand higher temperatures (400 ° C) but also withstand higher humidity (≥95%). Water vapor easily enters the cable inside high temperature and high humidity environment, making the cable The insulation and pressure resistance indicators are reduced, the power capacity is reduced, and a short circuit is caused in serious cases, resulting in system damage.

Qu Xiaosong, person in charge of the 203 projects of the Second Hospital, said: "The key points and difficulties in the development of high temperature sealed RF Coaxial Cable assemblies are the selection of Connector materials and the realization of the processing technology of cable assemblies." Based on the high-temperature cable assembly technology independently developed in 2015, the high-temperature, sealed RF Coaxial Cable Assembly was successfully developed. The successful development of this type of component has changed the situation that such products need to be imported in the past, and made important contributions to improving the autonomy of equipment and ensuring the development cycle of various scientific research tasks.
