Songshan has been the sole domestic supplier of fuses used in Chinese spacecrafts since the 1970s and supplied the supporting products to Chinese aerospace projects for nearly half a century. The fuse type RSG-I-FFA series developed by Songshan itself have been applied to all series of Chinese satellites, Long March launch vehicles, Shenzhou spacecrafts and Tiangong target spacecrafts. The reliability and stability of the fuse series reached the world's advanced level. So far, there has never been any quality problem, thus "foolproof" is truly realized.

In order to adapt itself to the rapid development of Chinese aerospace industry, Songshan increased investment and developed solid fuse type GRF series used in aerospace, which tops the world at present (equivalent to FM12 products as per American military standard). The GRF series passed a number of rigorous tests required in aerospace industry, especially, the simulated space environmental condition experiment, and further the GRF series passed the full performance tests and the performance is certified to fulfill and exceed the requirements of American military standard. Furthermore, the GRF series obtained the aerospace-grade certification SAST and passed the relevant quality assurance system audit of production sites. The GRF series have been widely applied in Chinese manned space projects and other spacecrafts.

As the only designated supplier of aerospace-grade fuse of Chinese aerospace, Songshan is ready to provide powerful solutions to similar circuit protection problems identified in the aerospace industry and other applications requiring professional circuit protection technologies. Songshan is also using its rich expertise and the technologies in aerospace to serve the customers from other sectors.
