GB/T 17737.2-2000

This standard specifies the requirements, test methods, and quality assessment procedures for semi-rigid radio-frequency and coaxial cables insulated with polytetrafluoroethylene (PTFE). It is applied in the telecommunications and electronics industries for high-frequency signal transmission, particularly in applications requiring stable electrical performance under extreme temperatures, such as in aerospace, military communications, and precision instrumentation. The standard ensures consistency in cable impedance, attenuation, and mechanical durability for use in connectors and assemblies.
