High-temperature resistant SiO₂-insulated flexible RF coaxial cable

High-temperature resistant SiO₂-insulated flexible RF coaxial cable

Silica (SiO₂) insulated RF cables use flexible silica as the dielectric medium. They feature an exceptionally wide operating temperature range, along with outstanding high-temperature resistance, radiation tolerance, and flame retardancy, making them ideal for high-frequency signal transmission in extreme environments.
